Your parallel battery kit works great. Instead of cutting the battery cable, and voiding my warranty, I cut the plug off a burnt out Radrover controller and soldered it to a female X90 plug. Works perfectly Thanks Stan, you're the Man!
Thank you for this excellent video, I searched endless videos how to connect with a Y splitter parallel and I wish people could just talk as plainly and simple as you did, its not a hard thing to grasp but for god sakes nobody just tells it as straightforward as you do man! Again thank you.
Good job on this video, I have been riding recumbent trikes for several years. I electrified my current trike and now I want to ride faster longer. By the way I'm 83 and still hot rodding. My set up is a Bafang mid drive with a 48 volt battery. Your video is a great help. Thanks for producing it.
Wow great video, I've looked everywhere on TH-cam for this explanation for cutting the wires under the frame and connecting new battery, I was so confused about the male and female connectors on other videos, but you made all so clear👍🏴
This is exactly the information I'm looking for! I currently have a Rad Rover 6 Plus and am looking to run two batteries in parallel. Although I couldn't find a video specific to my Rad Rover, this video helps tremendously! Thank you for posting! 👍
Very impressive. I'll never do this or try to change my settings, I'm just a go slow take my time kinda guy in retirement, but I still want to say you are an informative guy. I just like watching your videos. Never hurts to know more.. I've got about 2,500 miles on my bike
Just ran into your channel and gotta say thank you. You made dual battery hook up easy. Been wanting to do my bafang mid drive and also just purchased a himiway for my wife and wanted to add an extra battery. Awesome tutorial.
Happy to know that you can do this! I just ordered my Himiway and waiting for it to come in. My dad just got one as well and I’m very impressed with the stock battery. However, I definitely like to ride fast and I know for a fact I’ll be chewing up the battery quick. So I may be doing this in the near future
Wow! It’s incredible that the coincidences that we have makes me laugh when I saw the solder gun, I had to subscribe to your channel even though I was too buzy I watched whole video! You’re a great homemade hidden genuis!!
Good job mentioning the danger of simple parallel wiring. Hopefully everyone really paid attention to that. More than a negligible voltage difference can readily exceed the carrying capacity of the wiring or connectors which could be catastrophic. You could have mentioned that there are current limiting Y adapters designed for parallel eBike battery configurations that will limit the current passing between batteries of differing charge levels in order to ensure safety. Those are a smart inclusion in any parallel design as there are multiple reasons the batteries could become unbalanced over time. For example, over time, two widely differing batteries (e.g. cells from different manufacturers of differing quality) will reach two different top off charge voltages. Also, any faulty or loose connection to one of the batteries while riding will drain the other, creating a catastrophic connection once discovered and "fixed". For safety reasons, I would never recommend raw parallel connections like this. Also, for shrink wrap, the best has a type of hot glue on the inside to waterproof the connection. Of course that wouldn't work on your homebrew Y adapter, but you could pour silicone into the gap to seal it fully. However, there are multiple issues with your switch design using a 110v wall switch. First of all, an eBike like the Himiway has a microcontroller rated at 25A for maximum current from the batteries to the motor. So you are correct that any switch rated for only 15A or 20A will immediately have its rated capacity exceeded in daily use when accelerating under load, and likely at simply maximum cruising speed continuously exceeding it given the 750 watt motor in the Himiway. However, switches that are designed for DC as opposed to AC voltage are quite different in design of their contacts and the rating capacity doesn't carry over directly. Here is a discussion on the differences: www.cruisersforum.com/forums/f13/how-to-calculate-dc-switch-amperage-if-ac-amperage-is-known-249407.html In fairness, since we would assume the switch will only ever be thrown while stopped (I would never suggest anyone try and switch 48v DC under a load with anything other than a switch purposely designed to handle such a switching load in DC voltage), there will be minimal current passing from the battery to simply power the controller and display. Ideally the bike can be powered off each time the battery will be switched. Either of these may reduce or completely eliminate the arcing that occurs in DC switches when switching a load. However, it does not change the fact that a switch designed to carry 30A max at 110V AC will not necessarily be able to carry 20-25A under a 48V DC load without fusing or burning the contacts over time. Also, an indoor wall switch is about the worst option to be able to waterproof. A better switch would be a toggle switch, which can have a rubber boot over the switch to provide a degree of waterproofing: www.amazon.com/Blue-Sea-Systems-WeatherDeck-Toggle/dp/B000MMFIZS/ref=sr_1_21?crid=1XS1QOQ9OMYMK&keywords=waterproof+toggle+switch&qid=1640829928&s=sporting-goods&sprefix=waterproof+toggle+switch%2Csporting%2C93&sr=1-21 www.amazon.com/Autoec-Rubber-Toggle-Switch-Weatherproof/dp/B017SMTR42/ref=sr_1_1_sspa?crid=F1P5LD3LCN41&keywords=waterproof+toggle+switch+boot&qid=1640830765&s=sporting-goods&sprefix=waterproof+toggle+switch+boot%2Csporting%2C90&sr=1-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExODQ0VkFYQVZIN1gmZW5jcnlwdGVkSWQ9QTA3MzIzMTYyNTFRSzVSOTQ2M0hIJmVuY3J5cHRlZEFkSWQ9QTAwODQ5OTdLS1M2V1pVSTU3OUEmd2lkZ2V0TmFtZT1zcF9hdGYmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl Finally, the innertube is a horrendous idea for waterproofing, since it simply creates a funnel shape to capture water in the top which then passes through any air gaps between the multiple wires entering the top.

Thank you so much for showing us how to use I love it I live on the island in Southeast Alaska and I’m learning from the best. Keep up the great work love your channel thank you
Wow i have a 2nd battery wanting to do what the video is about ! I have a Himiway and another 17.5 48v lithium wanting to make my travel distance a monster. I plan to put the battery on the rear rack but have the slip on bag above the battery. I figure i can get 60 - 100 miles with just pedaling. Thanks Pat
It was a great video. It's kind of the same idea I had but wasn't sure. Didn't not know anything about the importance of the switch though that was a big plus. I do have one question though, what do you do about charging of the two batteries? Thank you for a great video.
After upgrading from a 10 to a 15ah battery, i feel as if its pointless to have two batteries connected to one hub. I would plan on adding a front hub motor, of the same wattage as the rear, vs doing all of this. Makes having two batteries more useful in my experience. You are still gonna be helping out the other battery by using both at the same time with two motors.
I put 4,000 miles on my Rad Rover -- I purchased a new Himiway Cruiser -- more power -- bigger battery -- BUT -- I need 2 batteries -- so I ordered another Himiway Battery -- $430 -- I don't have to rewire anything -- I just swap out the batteries -- every 1 & 1/2 hours -- because I need to go 60 miles -- not 30 miles in 1 1/2 hours -- I average 20 mph -
Hi stan I just bought a 52 volt 15 amp magicycle cruiser, I probably should of paid a little more and upgraded to the Cruiser pro which comes with a 52 vo!t 20 amp battery, anyway what battery can you recomend I use to do the upgrade to my magic cycle. Awesome video by the way
Hey Stan great video. My Himiway is being delivered tomorrow but not sure I will need and extra battery but would like to investigate a controller that provides higher current (AMPs) output maybe in the 30 Amp range. With a 48 volt battery and thirty Amp output you can deliver 1440 watts to the motor. This combo would make for a seriously powerful E-Bike. I do have a suggestion on making your parallel connector out of the XT90 plugs. I learned this while making up similar connectors for some of my RC Planes. I'm not sure you know this but the pins in the connectors rotate very easily allowing you to connect them better if the notches in the connectors are rotated so the notches align better. Also I would pre-tin the all connection points before attempting to solider them together this promotes better heat transfer. Also on you switch design there are single pole/double throw toggle switches that could used and put it in a small plastic project box available many places on line.
hello doing this to my radrunner I added a motorcycle headlight to mine(running off radbattery) and a switch for the light I used a 4 pin automotive relay and a cheap on off switch on amazon that mounts to my handlebar I spliced into the controller side(where battery cradle connects to controller to supply 48volts to a 48volt to 12 volt converter (used on golf carts) I use that convertor to power my 12volt items lights usb phone chargers etc ... I also put xt 90 anti sparks on my controller and my battery cradle .....now that you are up to speed with my situation my question is about the switch you used you stated that the local hardware store only goes up to 20 amp can't i use a cheap dinky handle bar switch that goes 3 ways and use it with a 40 amp automotive relay isn't that what the relay is for so that the switch dose not melt thank you
I'm waiting on my himiway. I think maybe the boat getting stuck in egypt slowed it down getting here. I'm nervous. I hope my order is correct., I hope there good honest ppl. God bless. Thanks for your vid
Hi Stan. Really liked your holiday dual battery. Just ordered new himiway.. I will be riding rail to trails in South western pa. Not sure if I need the pig tail yet. Will you be making more? Thanks
I have been thinking of building a couple of battery packs to runn on a bike but want to ne able to chang them out to be able to service individual batteries in a bank so something like this is qhat i need
Nice job. Would like to see the soldering of the double connector in more detail. Is there a way to verify a battery's amp hour size? I have a 19.2 ah battery that is physically smaller than a 17.5 ah battery pack. Makes me curious.
What's the power rating on that light switch? most are only rated for 15-20 amp. Also. they are not rated for an inductive load. that switch WILL be a problem.
Hi I have a standard e-bike and wanted to add another battery in parallel but I can't see a controller anywhere on bike and the tubes aren't thick enough to hide it inside. Plus the holes in frame are also to small for a controller to be placed inside. Is it possible that it does have one? 😕
This is well done Stan, I mean really well put together. I bought a Ride1up bike last summer and been reviewing posts on how to add a second battery. Your video covers all the topics and also the questions I had when researching how to do this safely and you have thought of everything. I do have a couple questions re. your parallel setup, are there any issues with charging, do you charge via the original battery, as the 2 batteries now make one 'large' battery, does it charge as expected? I am leaning towards the parallel set up and just wanted to know if you ran into any issues later on and hence installed the 3 way switch. And, the added battery you purchase on ebay, have you had good luck with that, does it have the performance listed? Lastly, re. your switched setup, you now have to charge each battery separately? Thanks so much for any information, I will look for your kit on ebay. Lothar, Stoughton WI.
In parallel setup you can charge using the original or the new battery. It takes longer to charge if both batteries are low. No issues running parallel, I just wanted to show how the switch worked. The ebay battery still works fine but I haven't had it very long. Using the switch you need to charge both batteries separately. Thanks for watching!
I am going to do a video on this. I've had the rad a long time and had lots of worry free miles. The Himiway is faster but I don't know if its as reliable.
And had you had any problems with it now. Because those may be 48v battery's but their ah look different and I don't want my bike discharging knowing that the BMS on both batteries weren't capable of reading and discharging the ebike equally
Different Ah doesn't matter. It's just the size of the resevoir so to speak. Your voltage has to be the same though. If wired in parallel your voltage remains the same and your Amp hours become added together to increase your overall capacity.
You could have saved destroying your wires cutting them if you researched series battery blenders.electric all wheels sell a blender kit that is a total plug in kit that includes wiring with the correct connectors . No cutting or soldering. $70 + shipping. Fits Radbike,Himiway and Magicycle.
Hello Stan, I have a 2019 Rad Rover. After seeing a video of a guy doing 35 miles per hour on the Himiway, and how much more torque it has off the line. I was immediately bummed out that I bought the Rad. You see, I want to go faster and farther. I find the Radrover to be a bit boring. So I'm not sure if I should sell the Rad Rover and get the Himiway, or if I should upgrade the Rad. I'm leaning towards upgrading the Rad's motor and controller, and buying a second battery to haul along and swap in and out. Or just forget the whole damn thing lol. Any suggestions?
Although the himi still has more power and acceleration, they have now limited the top speed to 26.8 And, there is no hacking there new display/controller :(
@@stanthereservoirrat5934 yes i understand that but one battery is originally 48v 30ah with 5a charger , and another battery is 48v 15ah with 2a charger, on second battery manual it says that 2a charger should be used ??? so using 5a charger can be problem then ?
Hey Stan an anybody else that might know about this. I;ve got a Him Cruiser. I might have a bike with a couple of not so good parts, but I;m starting to wonder if maybe this bike doesn't do so well in hilly areas. I hope not. Anybody have an opinion about this. Thanks ahead of time.
I see your point but the charge port may only be designed for charge current amps (3 amps possibly). Might have a melt down or possible fire hazard. I am surprised that I don’t see many posts of battery connection connector plug failures from over heating. Just thinking I would keep a close eye on battery connections. A lot of electrical problems start at dirty or poor connections.
Hi Stan. Just bought your parallel battery kit for my Himiway cruiser. I have an identical himiway battery with the mounting tray. Even though they're both 48v17.5ah, the Himiway charger is 2amp, and the charger for the other one is 3amp,and has a fan. If I'm running both parallel, which charger should I use to charge them parallel?
Hello because of a good Himiway bike After 3 weeks and about 15 km it is defective (no more pedal assist) After I tried the support they wanted a video from me with the description of the problem, what I had done. The driving assistance via hand throttle worked perfectly, what I showed in the video. And what email came back from China ??? a video how I can speed up the hand throttle illegally, with the statement that they helped me with it ????????? I think the Himiway Service in China can't even watch video properly. I've only had the bike 3 weeks and already have a neck on Himiway. I hope for you that you never have to use the service, because the support in Germany gives the problem also only to China, because nothing else comes from there either.
Have fun with your Himiway and hopefully never a warranty case.
I know this is a added cost Stan, but it is much safer and you don't have to cut all your wires up and can be put back to the original state at any time. DATE DX2 th-cam.com/video/pvumfnCff10/w-d-xo.html I've been using one for a while now and you can run either battery or both at the same time. Two Batteries not only doubles miles but even give you extra because of the extra cells it sips more slowly from each.
Why dont you use the Micro chip that controls both battery's and you dont have to worry about the battery's being at the same charge and you have much more control over the battery's if you do it this way the way I did and there is NO DANGER of BLOWING UP the battery's because one battery is NOT the same Quality as the other and it goes bad quicker By doing it with the Micro chip I used you just have to make sure the 2 battery's are rated at the same VOLTAGE like 2 48v battery's or 2 52v battery's is all you have to worry about with this chip you can go up to 60v battery's
It's a good idea but you really dont need to do that just get a second battery mount the battery bracket put the extra battery on your bike use it to hold your extra battery and just switch them when you need that battery really all your doing is giving convenience to push a button or switch doing it the other way
Anyone who try's to do it this way is just asking for trouble. multiple places for problems. go to Bolton bikes and watch his video. this can be DANGEROUS
Interesting - I have many 18 volt Milwaukee Batteries 9 amp hours each - so I use a 300 watt inverter - and a step down transformer - to 12 volts to power my inverter and charge my battery -
I decided to purchase another Himiway Battery -- $430 -- I need to go 60 miles -- not 30 to 35 miles -- I average 20 mph --- I just swap out the batteries -- no rewiring needed. -- plus my bike warranty is still A-OK
Hi, can you build me the extra pack with all the wirings on this video? I plan to use by itself not parallel. I really you can. Please let me know! Thank you so much!
You used AC switch for DC current, bad. You never connect batteries together like you did unless they are the same sized amps. You need to add a shottky diode that is only $3 and it will save hundreds of dollars because you are going to thrash your small battery pack. The big battery pack will be fine. Just solder one SBR60A60CT with heatsink in as the splitter and your battery will live a long happy life.
I ride for Hours and get to a place of I've had enough. I can get 30 miles on one battery bar. Have No Idea why I would ever want to hook up another 8 pound battery. Crazy - - - >>>
Rad is really just shooting themselves in the foot, by not upgrading the controller. I just picked up the Speedrid $950. It's $650 less and way faster.
@@Hoggdoc1946 na the Speedrid is faster than the Radrover, but not as fast as the Himiway. The Speedrid has a 18amp controller and tops out at 26mph with throttle only. 28 if you pedaling it a little. I'm pretty sure the 2018 Radrover has a 16.5 amp controller. The motor looks alot like the motor in the Himiway if you take it out of the case. (I think it's the same motor that's in the Lectric xp) Its bigger than the 500 watt motor that's in the Rad, but not as big as the true 750 watt bafang. Read the Reviews on Amazon the thing is a beast for the price.
Parallel is the way to go with equal batteries, if you half current for batery voltage drop less and power lossess less with square of current. Really you do not look for double the range what is even possible. For currents 5 or 10 A saving could be 5-10% even with additional weight in some intrrconnection lossess , main thing is avoid deep discharges, riding with higher voltages. Problem is space , xt60 excellent connector easy to put 2.5mm2 wire but hard to put 4mm2 which should be really in. 5% on 240V is 12V , but 12V on 48V is not 5% but 25%. XT90 EXcELLENT connector can put easily 6mm2 but relativly big hard to find space except outside. This time used smaller option if any problems , will go only min 4mm2 and xt90 connectors. The other problem found conector for derodo baterry but contacts not gold plated could be in DC environment good only for 10A? Normal use will be in avg 5A ? Cold be even voltage rating . On solid rear rack two batteries could be mounted on the side below rack level, if no side bags or if you put one or two bateries in the midle of the rack , bags could be on the side . Y connection only if BMS take care about reverse currents . Voltages never the same could be some suprises before or later.
Dean connectors are underrated and written off too much imo. They look much cleaner take up less space, And can handle 80-100amps with the ultra versions and when connected & wrapped properly they won't budge or take in weather so there's no real compromise over XT.

I put 4,000 miles on my Rad Rover -- I purchased a new Himiway Cruiser -- more power -- bigger battery -- BUT -- I need 2 batteries -- so I ordered another Himiway Battery -- $430 -- I don't have to rewire anything -- I just swap out the batteries -- every 1 & 1/2 hours -- because I need to go 60 miles -- not 30 miles in 1 1/2 hours -- I average 20 mph -
Hi stan I just bought a 52 volt 15 amp magicycle cruiser, I probably should of paid a little more and upgraded to the
Cruiser pro which comes with a 52 vo!t 20 amp battery, anyway what battery can you recomend I use to do the upgrade to my magic cycle. Awesome video by the way
Hey Stan great video. My Himiway is being delivered tomorrow but not sure I will need and extra battery but would like to investigate a controller that provides higher current (AMPs) output maybe in the 30 Amp range. With a 48 volt battery and thirty Amp output you can deliver 1440 watts to the motor. This combo would make for a seriously powerful E-Bike.
I do have a suggestion on making your parallel connector out of the XT90 plugs. I learned this while making up similar connectors for some of my RC Planes.
I'm not sure you know this but the pins in the connectors rotate very easily allowing you to connect them better if the notches in the connectors are rotated so the notches align better. Also I would pre-tin the all connection points before attempting to solider them together this promotes better heat transfer.
Also on you switch design there are single pole/double throw toggle switches that could used and put it in a small plastic project box available many places on line.
Xt90 plugs
hello doing this to my radrunner I added a motorcycle headlight to mine(running off radbattery) and a switch for the light I used a 4 pin automotive relay and a cheap on off switch on amazon that mounts to my handlebar I spliced into the controller side(where battery cradle connects to controller to supply 48volts to a 48volt to 12 volt converter (used on golf carts) I use that convertor to power my 12volt items lights usb phone chargers etc ... I also put xt 90 anti sparks on my controller and my battery cradle .....now that you are up to speed with my situation my question is about the switch you used you stated that the local hardware store only goes up to 20 amp can't i use a cheap dinky handle bar switch that goes 3 ways and use it with a 40 amp automotive relay isn't that what the relay is for so that the switch dose not melt thank you
I'm waiting on my himiway. I think maybe the boat getting stuck in egypt slowed it down getting here. I'm nervous. I hope my order is correct., I hope there good honest ppl. God bless. Thanks for your vid
Thanks. Just wanted to know; how does that affect the 900 cycles battery to connect it to a low quality battery with less charge cycles???
Could I use this on electric XP thanks for the great content very informative
As an R/C car guy, I’m curious if you have found the battery in the pack on back would be getting hot, potentially a fire hazard?
Yes, that looks like a fire hazard!
This is an excellent video, thank you! Subscribed!
Hi Stan. Really liked your holiday dual battery. Just ordered new himiway.. I will be riding rail to trails in South western pa. Not sure if I need the pig tail yet. Will you be making more? Thanks
Never seen anywhere on Bolton to get the replacement cable ??????
Good video. Easiest way obviously is just to carry an extra battery.
I have been thinking of building a couple of battery packs to runn on a bike but want to ne able to chang them out to be able to service individual batteries in a bank so something like this is qhat i need
Jamis uses a “double” level rack, with the space in between for their battery.
Nice job. Would like to see the soldering of the double connector in more detail.
Is there a way to verify a battery's amp hour size? I have a 19.2 ah battery that is physically smaller than a 17.5 ah battery pack. Makes me curious.
the himiway battery is bigger than it has to be. you can get higher amp hours with higher quality batteries.
What's the power rating on that light switch? most are only rated for 15-20 amp. Also. they are not rated for an inductive load. that switch WILL be a problem.
Hi I have a standard e-bike and wanted to add another battery in parallel but I can't see a controller anywhere on bike and the tubes aren't thick enough to hide it inside. Plus the holes in frame are also to small for a controller to be placed inside. Is it possible that it does have one? 😕
This is well done Stan, I mean really well put together. I bought a Ride1up bike last summer and been reviewing posts on how to add a second battery. Your video covers all the topics and also the questions I had when researching how to do this safely and you have thought of everything. I do have a couple questions re. your parallel setup, are there any issues with charging, do you charge via the original battery, as the 2 batteries now make one 'large' battery, does it charge as expected? I am leaning towards the parallel set up and just wanted to know if you ran into any issues later on and hence installed the 3 way switch. And, the added battery you purchase on ebay, have you had good luck with that, does it have the performance listed? Lastly, re. your switched setup, you now have to charge each battery separately? Thanks so much for any information, I will look for your kit on ebay. Lothar, Stoughton WI.
In parallel setup you can charge using the original or the new battery. It takes longer to charge if both batteries are low. No issues running parallel, I just wanted to show how the switch worked. The ebay battery still works fine but I haven't had it very long. Using the switch you need to charge both batteries separately. Thanks for watching!
Great vid! But Stan, how do you like the Cruiser compared to the Rover?
I am going to do a video on this. I've had the rad a long time and had lots of worry free miles. The Himiway is faster but I don't know if its as reliable.
@@stanthereservoirrat5934 Thanks Stan, must be crappy weather where you are right now, you responded immediately!
Sprad
Thanks!
Sir, thank you.
Stan, I agree you put together a very good video. Would you please answer Wood Sculpter's question. Thank you, Sprad
thanks, I guess I missed that one.
Brilliant!
Really interesting and informative vid, Thank you :)
Bro thanks for the video
And had you had any problems with it now. Because those may be 48v battery's but their ah look different and I don't want my bike discharging knowing that the BMS on both batteries weren't capable of reading and discharging the ebike equally
Why does it take so long to get the bike after you order it from Himiway?
It is made in CHINA and the bike doesn't travel over water very fast. :)
I dont know how I feel about matching batteries with different ah
Different Ah doesn't matter. It's just the size of the resevoir so to speak. Your voltage has to be the same though.
If wired in parallel your voltage remains the same and your Amp hours become added together to increase your overall capacity.
@@nicholasbrassard3512 How about wire it in series and quadruple your speed?
If I connect the batteries parrallel, can I just charge up one? Leave the spare on the bike and charge only the Himiway.
No. They both have to be at the same voltage when connecting parallel. Bolton bikes now sells a device that allows you to do what you want.
Your link to ebay not working
Hey. I’m in the Houston area. Can I pay you to configure that setup for me on my RAD Rover?
I just read your post about selling the wiring kit. Let me know so I can purchase the parallel setup. Thanks
I'm going to list the kit in a week. But you can email me at henchstan@gmail.com . I can wire it on your bike for you also.
Kits are now on ebay.
You could have saved destroying your wires cutting them if you researched series battery blenders.electric all wheels sell a blender kit that is a total plug in kit that includes wiring with the correct connectors . No cutting or soldering. $70 + shipping. Fits Radbike,Himiway and Magicycle.
so you do not need the module sold at Bolton Ebikes?
Oh Himaway.?/ I swear I keep hearing hemmingway
It would be safer to use the module sold by bolton. You don't need both batteries at the same charge level.
Hello Stan, I have a 2019 Rad Rover. After seeing a video of a guy doing 35 miles per hour on the Himiway, and how much more torque it has off the line. I was immediately bummed out that I bought the Rad. You see, I want to go faster and farther. I find the Radrover to be a bit boring. So I'm not sure if I should sell the Rad Rover and get the Himiway, or if I should upgrade the Rad. I'm leaning towards upgrading the Rad's motor and controller, and buying a second battery to haul along and swap in and out. Or just forget the whole damn thing lol. Any suggestions?
I would not upgrade the rad. sell the rad and buy a himi.
Dont waste money on upgrades, Sell the Radrover and buy a Himiway cruiser
Although the himi still has more power and acceleration, they have now limited the top speed to 26.8
And, there is no hacking there new display/controller :(
Great Job Thanks .
do you need to charge each battery with its own charger or ?
Once they are connected, you only hook up one charger and they both will charge.
@@stanthereservoirrat5934 yes i understand that but one battery is originally 48v 30ah with 5a charger , and another battery is 48v 15ah with 2a charger, on second battery manual it says that 2a charger should be used ??? so using 5a charger can be problem then ?
Thats an upcoming video! I had to upgrade the battery before I got the bike dirty! I only have 30 miles on it!
Thank you so much for this great video. Easy to follow and very well done. Thank you so much. Most appreciate💯🙏
Hey Stan an anybody else that might know about this. I;ve got a Him Cruiser. I might have a bike with a couple of not so good parts, but I;m starting to wonder if maybe this bike doesn't do so well in hilly areas. I hope not. Anybody have an opinion about this. Thanks ahead of time.
With all due respect. Why can't the backup battery just be wired to be plugged into the charge port of the stock battery??
I see your point but the charge port may only be designed for charge current amps (3 amps possibly). Might have a melt down or possible fire hazard. I am surprised that I don’t see many posts of battery connection connector plug failures from over heating. Just thinking I would keep a close eye on battery connections. A lot of electrical problems start at dirty or poor connections.
That was deal on the heat shrink.
BEAUTIFUL 👌
Thanks
Hi Stan.
Just bought your parallel battery kit for my Himiway cruiser.
I have an identical himiway battery with the mounting tray. Even though they're both 48v17.5ah, the Himiway charger is 2amp, and the charger for the other one is 3amp,and has a fan. If I'm running both parallel, which charger should I use to charge them parallel?
i would use the 3amp. it would be faster. both would work.
Thanks
Could this method work with the step thru ?
I don't have access to a step thru but I would think so.
@@stanthereservoirrat5934 thanks so much for the quick response.
Would upgrading the hub motor make it more fastest ?
Hello because of a good Himiway bike After 3 weeks and about 15 km it is defective (no more pedal assist)
After I tried the support they wanted a video from me with the description of the problem,
what I had done. The driving assistance via hand throttle worked perfectly,
what I showed in the video.
And what email came back from China ??? a video how I can speed up the hand throttle illegally,
with the statement that they helped me with it ?????????
I think the Himiway Service in China can't even watch video properly.
I've only had the bike 3 weeks and already have a neck on Himiway.
I hope for you that you never have to use the service, because the support in Germany gives the problem
also only to China, because nothing else comes from there either.
Have fun with your Himiway
and hopefully never a warranty case.
What happened to the rad?
I still ride the Rad all the time. I just put out a Rad video. I'm just adding to my collection of ebikes.
I know this is a added cost Stan, but it is much safer and you don't have to cut all your wires up and can be put back to the original state at any time. DATE DX2 th-cam.com/video/pvumfnCff10/w-d-xo.html I've been using one for a while now and you can run either battery or both at the same time. Two Batteries not only doubles miles but even give you extra because of the extra cells it sips more slowly from each.
Why dont you use the Micro chip that controls both battery's and you dont have to worry about the battery's being at the same charge and you have much more control over the battery's if you do it this way the way I did and there is NO DANGER of BLOWING UP the battery's because one battery is NOT the same Quality as the other and it goes bad quicker
By doing it with the Micro chip I used you just have to make sure the 2 battery's are rated at the same VOLTAGE like
2 48v battery's or 2 52v battery's is all you have to worry about with this chip you can go up to 60v battery's
It's a good idea but you really dont need to do that just get a second battery mount the battery bracket put the extra battery on your bike use it to hold your extra battery and just switch them when you need that battery really all your doing is giving convenience to push a button or switch doing it the other way
i run 2 in parallel.. charge and use in parallel... so controller and charger just see a bigger pack
Anyone who try's to do it this way is just asking for trouble. multiple places for problems. go to Bolton bikes and watch his video. this can be DANGEROUS
Gibts doch nich wie haste das denn da drangepappt
Interesting - I have many 18 volt Milwaukee Batteries 9 amp hours each - so I use a 300 watt inverter - and a step down transformer - to 12 volts to power my inverter and charge my battery -
I decided to purchase another Himiway Battery -- $430 -- I need to go 60 miles -- not 30 to 35 miles -- I average 20 mph --- I just swap out the batteries -- no rewiring needed. -- plus my bike warranty is still A-OK
Hi, can you build me the extra pack with all the wirings on this video? I plan to use by itself not parallel. I really you can. Please let me know! Thank you so much!
You used AC switch for DC current, bad. You never connect batteries together like you did unless they are the same sized amps. You need to add a shottky diode that is only $3 and it will save hundreds of dollars because you are going to thrash your small battery pack. The big battery pack will be fine. Just solder one SBR60A60CT with heatsink in as the splitter and your battery will live a long happy life.
I ride for Hours and get to a place of I've had enough. I can get 30 miles on one battery bar. Have No Idea why I would ever want to hook up another 8 pound battery. Crazy - - - >>>
This is a recipe for disaster. You have to use an ideal diode circuit between those two batteries.
That ac switch wont last, the dc will fry it
Absolutely do not add a second battery by this yahoo's way of doing it. Use a series battery blender that connects the batteries correctly!
Yep! Let's se if it caught on fire.
Rad is really just shooting themselves in the foot, by not upgrading the controller. I just picked up the Speedrid $950. It's $650 less and way faster.
I wouldn't race either the RAD or Himiway because both those bike are much faster. The Himiway being the faster of the two.
@@Hoggdoc1946 na the Speedrid is faster than the Radrover, but not as fast as the Himiway. The Speedrid has a 18amp controller and tops out at 26mph with throttle only. 28 if you pedaling it a little. I'm pretty sure the 2018 Radrover has a 16.5 amp controller. The motor looks alot like the motor in the Himiway if you take it out of the case. (I think it's the same motor that's in the Lectric xp) Its bigger than the 500 watt motor that's in the Rad, but not as big as the true 750 watt bafang. Read the Reviews on Amazon the thing is a beast for the price.
@@Hoggdoc1946 Speedrid is the model the manufacturer is Ancheer
Booooom
I would check with Himiway before making these types of alterations. It’s your bike but it’s their warranty.
I just carry an extra battery in my backpack it’s a lot easier.
Email me. Henchstan@gmail.com
Help me buy your kit Stan Left message at ebay.
Parallel is the way to go with equal batteries, if you half current for batery voltage drop less and power lossess less with square of current. Really you do not look for double the range what is even possible. For currents 5 or 10 A saving could be 5-10% even with additional weight in some intrrconnection lossess , main thing is avoid deep discharges, riding with higher voltages. Problem is space , xt60 excellent connector easy to put 2.5mm2 wire but hard to put 4mm2 which should be really in. 5% on 240V is 12V , but 12V on 48V is not 5% but 25%. XT90 EXcELLENT connector can put easily 6mm2 but relativly big hard to find space except outside.
This time used smaller option if any problems , will go only min 4mm2 and xt90 connectors.
The other problem found conector for derodo baterry but contacts not gold plated could be in DC environment good only for 10A? Normal use will be in avg 5A ? Cold be even voltage rating .
On solid rear rack two batteries could be mounted on the side below rack level, if no side bags or if you put one or two bateries in the midle of the rack , bags could be on the side .
Y connection only if BMS take care about reverse currents . Voltages never the same could be some suprises before or later.
Dean connectors are underrated and written off too much imo. They look much cleaner take up less space, And can handle 80-100amps with the ultra versions and when connected & wrapped properly they won't budge or take in weather so there's no real compromise over XT.
