Hey man much respect for your setup and wat a cool bike 😎,,its been about a year now how are things going with your bike ,is it stilll ok the reason i ask is ive a 11ah and a 18ah that i want to join both 48volt and i dont think i need them boxes ive got some xt90s doubled up do u honestly think ill be ok doing rhis seens theres a big gap between batteries like 7ah ,i would still chrge the batterys in there normal ports would that be ok to have everything plugged un and chargeing with 2 charger s, god bless man ive subbed 👍
No matter the current as long as the nominal voltage is the same you can join them via XT90 for parallel connection. A lot of people that use range extenders use ones with low amp hours.
Can you mix different amp BMS? I have no idea what the stock bms is. I'm running a72v 3,000watt, 40ah battery and i want to add another 72v 40ah battery for range. However there are allot of options but with different bms. Such as 100a, 200a etcetera. Thank you for you time
Fantastic video, thank yoiu so much, do you need to keep both batteries on in order to charge from only one port? also when riding do both batteries need to be on?
Thanks dude! The bag is from this upholstery guy on Instagram instagram.com/vinylbybobby?igshid=MmJiY2I4NDBkZg== His name is Bobby and he does most of the community's battery bags for Powerful Lithium and E-Street Bikes
Good video with some great info JB!!! When charging the batteries at the same time, any chance/risk of overheating been that there's no blender? Or the bms in the batteries will work as a fail safe???
No overheating and if you connect your other charger to the other battery port, you will essentially speed up your charge time. The BMS will always prevent any overheating. I just wouldn't charge your batteries for any longer than 12 hours unattended.
If you are charging both batteries simultaneously with one charger, that means that one battery is charged through its discharge port. Maybe I'm mistaken but I believe that charging through the discharge port bypasses the BMS, which could lead to overcharging and other issuess. The battery that is charged via the charging port will be protected. But the second battery won't.
Not necessarily because once your packs are paralleled they act as one system. The packs itself won't allow overcharging anyways due to the limitations both BMSs have in place.
Too much complicated for saving 30 bucks on blender. In this set up can't be charged batteries over discharge port. BMS will not control charging. I run 3 batteries w/2 blenders w/no any problems.
Charging via discharging port does not neccesarily cause problems. It depends on the BMS. As for the jbd BMS's (which I'd recomend anyway due to the BT connection that allows configuration and Controll over the Battery) I don't even used the charging port. Interestingly I can turn off charging via software while leaving discharging on and it would not charge although the charger is connected to the discharge port.
Thanks for making this video. I was curious do you have a preference on which battery you charge when running parallel (main or secondary)? Do you use the one with a better charger cable? I didn't know you would be able charge both at the same time with one charger till I watched this.
@@JB360_NYC Thanks, I do have an additional question and hoping you might have some insight. I manage to run the parallel setup with a UPP triangle battery and AR stock battery. Although, I was wondering if you keep both batteries "powered on" at all times even when you are not using the bike. Normally when I was using a blender, the triangle battery has a "power switch/button" on the battery itself that I would turn off the battery when not using the bike. Can I turn the power off when running the parallel setup or would this mess up the voltage balance between the two batteries? Any insight on this would be appreciated, so far everything is working. Hope this made sense lol...
@@Nuf1av0r Yes this is a great question. So the simple answer is yes, both have to be on in order to hold the charge. The shark battery I have up top also has the power button as well so it was definitely a question of mine when I first did the parallel connection a couple of years ago.
Anne from nbpower said dont because the BMS are separate, my question to her is how does it not double the amp even if the BMS are separate. Is she trying to confuse me or is there's something im missing out on?
@@kiiingrook8592you're missing out on electronic theory. Say 1battery is 40amp with BMS max discharge/peak of 80 and another that's 35 amp and 75peak. Combining in parallel you are assuming that functions same as within the pack or in combination with modules, wrong. The BMS for each limits are for each individual battery respectively so combining in parallel your now 75amp continuous and 150 peak is far beyond the capabilities of the BMS to control. Now the same controller will ask for the same amps of your original battery, say the 40amps so you're just increasing range and time but when you think your amp increase from both batteries in parallel means you can upgrade your controller for 150peak...You've made a 🔥🚒. Please do not do this 🙏,
Thanks for the tutorial man! By the way, I'm wondering how you have your tuning set up on the MQCON app? I also picked up Sal's E Street Cannon kit and I know it should probably be tuned a little differently from how Sal does in his tutorial video. Thank you very much in advance
👍 Nice... Do you know how people are getting 60 mph off 60v system while others only get 50s on 72v ? I assume its controller but is it matter of preserving lifespan of batteries? You would think people would want highest amp possible? Thanks, and love your content!!
@@kevinduprey9326 thanks! So yes like you mentioned, it's mainly the controller and the type of BMS the battery is suited with. On the flip side, 72v batteries will always be better on the range side than 60v, since they take longer to discharge from their starting voltage.
@@JB360_NYC . NICE, obtained some 80v green works batteries and will harvest the good ones. I was thinking about getting solder less kit because I'm not to good at it. Unfortunately I know from making vape devices that every added connection causes voltage drop. Vaping with hybrid mechanical mod with direct battery contact is noticeably stronger than devices with added connections. I can only imagine the difference in EV's using hundreds of cells.
does using a battery blender thing have any advantage over just doing a setup like this? i understand the battery blender prevents energy flow from one battery to another, but does this actually help in safety in any way? also how would you recommend i go about connecting 3 batteries in parallel?
One advantage would be that you don't have to match voltages like here so it's mainly just plug and play with no volt meter required. Just note the blender does hinder the top speed a bit especially with 72V batteries. Sal and I tested parallel connection vs a 90a blender and difference was about 7 mph. If you're planning to do a 3 parallel connection, you would just need a custom harness with 3 discharge cables instead of two and just follow the same steps with all 3 batteries.
Hi great video can anyone tell me if you can run a older battery in parallel with a new battery and does it matter if they are different cells? All that matters is that both batteries are the same voltage Thanks
Good question but i think once your getting the same voltage number or very close then i cant see why not ,go for it bro ,im goin for it just waiting on a reply here to confirm and im connect ing a 18 ah to a 11ah 48 volt and the 18 is a older battery
I have a 48v 7.8ah, and a 48v 10ah battery. If I charge them both to full capacity will it be safe to parallel them without checking the voltage, I don't have a volt meter
I would recommend getting one just in case because you don't want to be too far off in terms of actual voltage. They're actually not that expensive on Amazon. The one I found is like 12 bucks and works great.
@@boulokid1977 not often at all. As long as that y-cable or parallel connector is connected to both batteries, you're good to go unless you physically disconnect them for some reason. Also, if you're curious, just measure both batteries as soon as they're connected and they should read the exact voltage to the decimal. That's how you know you have a successful parallel.
Will it not take twice the time to charge with only one charger..... Can you charge each battery with its own charger or would they need to be disconnected beforehand for two chargers?
Correct! You can use one charger to charger both and it will take longer or if you have a secondary charger just plug it into the other charge port for the second battery and it will speed up the charge time.
I am new to the e bike mod world and i consider myself a novice, but i thought the purpose of the blender was that you can mix & match batteries regardless of V&Ah with no need to worry about charge levels and or to worry about having a meltdown w/the barries? Or did i misunderstood the point of the blender regardless of the make? Please advise and keep up the good work and ride safe! LB
You are correct! The battery blender will suffice if you're linking 52V to 52V or 48V without worrying about levels but once you get to the higher voltages like 72V, we've found the higher rated battery blenders almost hinder some of the torque and acceleration. Parallel connections provide a more direct connection resulting in better battery performance while the two batteries are linked.
There's actually a guy on Instagram that does a lot for the Ariel Rider community. His name is Bobby and here's his profile instagram.com/vinylbybobby?igshid=YmMyMTA2M2Y= Definitely reach out to him. He uses really good quality for his bags as well.
I want to make a triple battery parallel connection, I have two 48V/13AH battery and one 48V/21AH battery. Can I use this way to use and charge them? And could I charge with multiple charges at the same time?
When I connect the batteries together and my controller pulls 50amps,will the controller split the amps from each battery? (I’m connecting four 72v 20ah batteries in parallel) just wanna make sure before I run it… ty
@@FA-cc7ng the controller will treat the paralleled batteries as a whole so the 50amps will discharge equally among the 4 batteries at the same time. Now if the amp hours are varying, it will discharge from the lowest ah first.
@@JB360_NYCnope.. lowest Ah will have higher internal resistance... so lower current from smaller pack. higher current from bigger pack... so they perfectly discharge in parallel keeping voltages the same
Does the amperage of the BMS have to be the same for both batteries? I want to add a second battery to a 72v 3,000watt hub moter. There are allot of options with different amp BMS available, I don't know what my stock is. @@JB360_NYC
please, I think you agree with me that nothing is better on the market than Dx2 Dx2c, etc blenders, with them you can mix juice and voltage. I've got 48V 17,5aH and 52V 20aH running so good no fuss no issues.
For sure, I think for a lot of riders it takes the hassle out of matching voltages with a voltmeter. For higher output applications, paralleling guarantees you get the most out of both packs.
What is there two batteries and 2 controllers can you do a similar connection also I have a 15 amp hour battery in a 20 amp hour can this be done with non-matching amp hours
I have an xclass 52v 18a, 1000w Motor, 33a controller and I added a 52v 20a second battery. Charged it up and connected with a 40a Double Battery Pack Balance Discharger I got from Alibaba, I rode it for like 5 mins and it shorted out My display and cables any suggestion of what could’ve caused the problem? Plz help 🙏🏽
This happened when I first got my x-class and used the battery blender. Check and make sure your battery connecters are fully plugged in as well as the motor cable...any kind of separation can cause an arc shorting out the system
@@JB360_NYC I have 2 72v 20ah batteries that are paralleled and 2 72v 5amp chargers and I always disconnect everything when I charge them but it's a hassle, I want to charge both of them while they are connected
What's the point to connect your 2 batteries when yiu need to decrease the voltage from one battery to meet the voltage another battery running Yr bike for a while. So, I need to have my multimeter in my pocket and after every charge if I'm charging separately with charger for each battery, to check all the time the voltage?
No the multimeter is only used for the first time when paralleling the batteries to measure and make sure the voltages are at the same level. After a successful parallel connection you don't need to do anything else and can charge both batteries from either port.
I put a 2000 watt kit on my x class with a second battery and y style connection to run both batteries together, both 48v.Everything runs good 38mph but the batteries drain super quick and don't seem to fully charge and experience brief sag or power delay when running, very annoying and I have no idea how to deal with it. Could be crappy y battery connectorr?
I would just double check the voltage levels on both to make sure they match. If the voltages don't match then I would try to parallel them again. 2000w is pretty demanding as well especially for a 48v setup which could be the reason also for the battery drain. What kind of controller are you running?
Couldn't you just use 3 Skokie diodes one on each battery ? That way as long as there all same voltage there can't be a heavy rush of current from one to another if voltage is off a little and if one cell shorts it will only affect one battery ? I use cell fuses on my DIY batteries just in case but it seams , as long as the diode rating is higher than the power in my case double the controller needs it would be safe . I am about to try adding 2 more diy 36v 20ah batteries in a saddle bag to increase my range
Awesome VIDEO, I just hooked up my Dualtron Storm battery to my Wolf King GT and I can say this thing is now the ultimate scooter. Basically 67AH. Check out my latest video's on it. On my bike that's like the LECTRIC, I run 2 of the same batteries in parallel at the same time and I get 3 times the range. check out my lastest shorts .
vas enseñando a prenderle fuego a las baterias de la gente!!! .lo mejor del video es el final al ver como compruebas las baterias ya conectadas en paralelo ya que mires donde mires marcaran el mismo Voltaje sin tener en cuenta la corriente parasita ni corriente revertida ni asistencia de frenado del motor..osea un peligro
Depends if you have for example a shark pack that has an on switch then yes both batteries need to be on to complete the parallel connection. Most high voltage packs don't have that switch so you don't need to worry about it.
9:00 be sure not to touch your two probes and short out the battery when doing this test :). Melted leads will suck. Would be a cool project if you install a digital volt meters to the batteries with some switches to make it easier to check battery before each ride
So if the voltages don't match a lot of times both batteries may cancel each other and can result in voltage drop. Are you noticing any difference in range than before?
@@JB360_NYC idk I rode it for about 3 miles to test it out then saw this video lol. I parallel connected them now. But what would happen if I run a 60v battery with the stock 52v ? Google says in order to parallel connect 2 batteries, they have to be the same voltage. Would it damage anything ?
@@ItsNoe yes when paralleling them you want to stick with the same voltage to reduce the risk of damaging both. This can damage the cells especially the smaller voltage pack.
@@JB360_NYC ok good to know. Would the DATEx2 60A be sufficient ? It’s a 60v controller, stock batter is 52v 18ah and battery I plan on getting is 60v 24ah
What about when it's time to recharge do you have to do this process where the battery have to have same voltage before you connect them Again? Do you charge the batteries independently? If not is it only charging via One battery charge port and not messing up balance charge on the second battery?
Once the batteries are linked and paralleled you don't need to repeat the process as you can now charge from either battery port which will charge both batteries at the same time. The awesome thing is too is if you have another extra charger, you can insert the extra charger into the second battery port and essentially speed up your charge time by half.
@@jbar3337 yes with two controllers, you would just need another y splitter cable so both controllers controllers can link to the batteries. Essentially the y cable connectwd to your batteries will connect to the y cable for your controllers.
it depends!!! I use a y splitter cable also on my charger... so I charge and discharge in parallel and in all cases the voltages stay equal BUT I had to add a diode in my upp pack cause my genuine pack also had one (no voltage measured on charge port) now both have an inline diode on charge port (roughly same voltage drop)... on charge and use both are paralleled and voltages match
side note.. in the minus rail cable of the charge port a 5 Amp diode added yes it plays a role where you add it (if you leave the packs connected on discharge port)
@@allan2502 you will get a slight increase in torque and top speed. In terms of the BAC app, you should not have to adjust anything unless you want the controller to pull more amps you should be fine.
Something does not seem correct you cannot solely rely on the voltage reading from a batteries charge port it it can be possible that the charge and discharge ports are giving different readings (if in the event of a faulty BMS, the state of charge cannot be accurately measured by just checking the charge port i think it would be safer to check each cell group of each battery and technically try to balance each battery before putting them together in parallel

This happened when I first got my x-class and used the battery blender. Check and make sure your battery connecters are fully plugged in as well as the motor cable...any kind of separation can cause an arc shorting out the system
@@JB360_NYC Did any components get damaged after this?
@@youngjay914tv9 no damage just had to re-secure my battery connectors and didn't have that issue again
Can I run a 48v 14ah battery with a 48v 13AH battery
I have two upp 72v 19.2ah 50a bms. Can i do the aame thing? Indont wanna lose power with the discharge module
Yes you can just make sure they're at the same voltage level when you connect them
@@JB360_NYC I did. It's awesome. I just unplug them to charge
I really thought about doing this instead of paying $50+ for a blender, but was afraid of damaging things, so I just bought 2 for three batteries...
Oh man back when the blender came out it was pretty expensive and was close to $100 so $50 each actually isn't a bad price.
Can you still do regen?
Yup regen still works as long as it's enabled on your controller
if the pack can.. yes.. some BMS can only discharge on one port and charge on the other
Can you charge the 2 batteries at the same time with 2 different chargers
With different amperages yes you can. Just be sure your outlets can handle the amperage.
@@JB360_NYC I have 2 72v 20ah batteries that are paralleled and 2 72v 5amp chargers and I always disconnect everything when I charge them but it's a hassle, I want to charge both of them while they are connected
@@ERICM429 yes with that setup you can absolutely use 2 chargers
What's the point to connect your 2 batteries when yiu need to decrease the voltage from one battery to meet the voltage another battery running Yr bike for a while. So, I need to have my multimeter in my pocket and after every charge if I'm charging separately with charger for each battery, to check all the time the voltage?
No the multimeter is only used for the first time when paralleling the batteries to measure and make sure the voltages are at the same level. After a successful parallel connection you don't need to do anything else and can charge both batteries from either port.
Ok, so, you are not going to check on every single time?
@@pavlovauk9162 nope you don't need to
not all packs can be charged from the discharge port..
I put a 2000 watt kit on my x class with a second battery and y style connection to run both batteries together, both 48v.Everything runs good 38mph but the batteries drain super quick and don't seem to fully charge and experience brief sag or power delay when running, very annoying and I have no idea how to deal with it. Could be crappy y battery connectorr?
I would just double check the voltage levels on both to make sure they match. If the voltages don't match then I would try to parallel them again. 2000w is pretty demanding as well especially for a 48v setup which could be the reason also for the battery drain. What kind of controller are you running?
Couldn't you just use 3 Skokie diodes one on each battery ? That way as long as there all same voltage there can't be a heavy rush of current from one to another if voltage is off a little and if one cell shorts it will only affect one battery ? I use cell fuses on my DIY batteries just in case but it seams , as long as the diode rating is higher than the power in my case double the controller needs it would be safe . I am about to try adding 2 more diy 36v 20ah batteries in a saddle bag to increase my range
Less than a volt difference is safe-ish. You certainly want both batteries exact or less than a .5v difference for safety.
GREAT VIDEO!
So u only need to connect 1 charger and it charges both?
Yes sir 👍
Awesome VIDEO, I just hooked up my Dualtron Storm battery to my Wolf King GT and I can say this thing is now the ultimate scooter. Basically 67AH. Check out my latest video's on it. On my bike that's like the LECTRIC, I run 2 of the same batteries in parallel at the same time and I get 3 times the range. check out my lastest shorts .
Looks great dude ⚡⚡
vas enseñando a prenderle fuego a las baterias de la gente!!! .lo mejor del video es el final al ver como compruebas las baterias ya conectadas en paralelo ya que mires donde mires marcaran el mismo Voltaje sin tener en cuenta la corriente parasita ni corriente revertida ni asistencia de frenado del motor..osea un peligro
Im a bit confused do bothe battery need to be on
Depends if you have for example a shark pack that has an on switch then yes both batteries need to be on to complete the parallel connection. Most high voltage packs don't have that switch so you don't need to worry about it.
9:00 be sure not to touch your two probes and short out the battery when doing this test :). Melted leads will suck.
Would be a cool project if you install a digital volt meters to the batteries with some switches to make it easier to check battery before each ride
For sure! I'm actually going to be adding it to my DIY pocket pike I'm putting together
Damn. What happens if you don’t do this ?? I just installed 2 batteries with that adapter and rode it for a few miles
So if the voltages don't match a lot of times both batteries may cancel each other and can result in voltage drop. Are you noticing any difference in range than before?
@@JB360_NYC idk I rode it for about 3 miles to test it out then saw this video lol. I parallel connected them now. But what would happen if I run a 60v battery with the stock 52v ? Google says in order to parallel connect 2 batteries, they have to be the same voltage. Would it damage anything ?
@@ItsNoe yes when paralleling them you want to stick with the same voltage to reduce the risk of damaging both. This can damage the cells especially the smaller voltage pack.
@@JB360_NYC ok good to know. Would the DATEx2 60A be sufficient ? It’s a 60v controller, stock batter is 52v 18ah and battery I plan on getting is 60v 24ah
@@ItsNoe yes using the DateX2 60a would be sufficient and safe as long as your combined AH are under 60amps.
What about when it's time to recharge do you have to do this process where the battery have to have same voltage before you connect them Again?
Do you charge the batteries independently?
If not is it only charging via One battery charge port and not messing up balance charge on the second battery?
Once the batteries are linked and paralleled you don't need to repeat the process as you can now charge from either battery port which will charge both batteries at the same time. The awesome thing is too is if you have another extra charger, you can insert the extra charger into the second battery port and essentially speed up your charge time by half.
@@JB360_NYC thank you.
What about running two controllers off this parallel battery connection?
@@jbar3337 yes with two controllers, you would just need another y splitter cable so both controllers controllers can link to the batteries. Essentially the y cable connectwd to your batteries will connect to the y cable for your controllers.
it depends!!!
I use a y splitter cable also on my charger... so I charge and discharge in parallel and in all cases the voltages stay equal BUT
I had to add a diode in my upp pack cause my genuine pack also had one (no voltage measured on charge port)
now both have an inline diode on charge port (roughly same voltage drop)... on charge and use both are paralleled and voltages match
side note.. in the minus rail cable of the charge port a 5 Amp diode added
yes it plays a role where you add it (if you leave the packs connected on discharge port)
Does it need to the same AH?
No they do not they can be different amp hours
@JB360_NYC will parallel battery increase speed and torque
I have a bac4000 controller do I need to retype my bike
@@allan2502 you will get a slight increase in torque and top speed. In terms of the BAC app, you should not have to adjust anything unless you want the controller to pull more amps you should be fine.
@@JB360_NYC is their a parallel connector for supra connectors?
@@allan2502 not sure specifically for the Supra connectors but I did see a Supra to QS8 connector online which you can use
Something does not seem correct you cannot solely rely on the voltage reading from a batteries charge port it it can be possible that the charge and discharge ports are giving different readings (if in the event of a faulty BMS, the state of charge cannot be accurately measured by just checking the charge port i think it would be safer to check each cell group of each battery and technically try to balance each battery before putting them together in parallel
