How much the battery and charger

WHY DIDNT YOU SHOW US HOW TO TEST VOLTS YOU JERK!

Regen mod is cool I will be doing this to mine very soon, but...how do you get the display on the phone??? its awesome!

I like when you can take out the battery and easy to put a new fully charged

All my cells test good but output on circuit bord is close to nothing.. any advice?

you said that you set the throttle up some how so you do not need the starting push roll to get it going ... i have looked for this setting in the manual and online but can not find it; can you give a detail description on how to set this up so you do not need the starting push roll ? ... i want to just push the throttle only to start going ... no push off needed. thank you gordonr

how is it going after 4 years? any problems or tips for improvments?

Hi thanks for the insight would this be done on the low brakes or hight brake option

Can you show how you tested cell group?

Good video !

absolutely clueless

pm me can you to install do sola paint of charger....

Thank You for All that you are doing for our Planet Earth.... Peace.. Shalom.. Salam.. Namaste 🙏🏻 😊 ✌ ☮ ❤ 🕊

Thank you My good man for doing this video, I've been thinking about doing the same thing to my truck. Great Idea for the bolt issue. Yes sir GM could learn a few things from the (Little Man) Great job 👍

Why not simply connect two identical laptop chargers in series 19 volts + 19 volts

Great job! I have already recell this kind of battery, but after I switched on the battery (yellow wire to ground) I can measure only 31V at the discharge port. Charging working well and on the battery charging port, I can measure 41,2V. What could be the problem? Thanks for your help in advance.

What was the cost of this build? I’m really interested in building a battery like this. Thank you for the video!

These work really good 4s 4p Headway 38140S 12Ah LiFePO4 Cell... 8 batteries total

I have the same scooter, same battery, battery is showing 29.2V, and the scooter is not working. Is that enough or do i need dissemble the battery pack or it's problem with controller? Thanks for your answer.

Quick question. Is the charging amps is 60 at 12.4-14.7, for example. Is it okay even though the alternators output is 180amps? Does the bms shorten its life?

I'm thinking about doing that I known my dad did that and added bigger tires. I think it would be better or able to tow my 5 wheel trailer but I guess that might be illegal because it be more towing then the truck is recommended to tow. So maybe removing stuff from the trailer would be better.

As im here is not a beautiful day 🥴

I had ABS solder pad on mine. It worked!! Thannk you so much. But im not sure this fills up the battery back, also im not sure if there is any settings on my sw900 lcd panel. If someone notice me about that will be happy. My hub fits nicely on the chsasis, but a torque arm may still be needed, will see.

Great video link the inverter please

Great video link the inverter please

What's the name of the step up inverter where did you get yours and how much was it to purchase? Can you send a link

THANK YOU FOR SHARING ❤

Good video sir, anyway can you bump up the out put current more than the input current can produce and what is that 4.1 volt per cell, is that charge voltage per cell. Thanks

what the cco?

Excellent work. Like your approach and the bolt recommendation. I will be doing the same to my 03 Z71. Thanks for taking the time. Life saver I should add.

Hi, what are the symptoms of a bad battery. I bought scooters similar to this one. It doesn't turn on all of the sudden.

You're a lifesaver

Can you tell me what the real voltage comes in the original charger? I bought a used tool without a charger, but I have a lot of adapters/chargers with different voltages. The batteries need 8.4v, but I think there is a voltage drop before it arrives in the batteries. I need a charger with more than 8.4v. If you can check the voltage that comes in the original charger I appreciate. Thks

one small problem.... the chair still has an airbag in it.

good but there is no led state to know is completely charged

Is there a way to do this for the Gotrax GXL V2 scooter battery?

good video, thanks dude

Very cool! That should be the default setting on every e-bike with a hub motor. You wouldn't even need a rear brake!

You might consider putting your new battery in the back, as LiFePo4 batteries don't like heat.

What for is that middle yellow wire?

thanks for your instructable/video, permit me one question, you are using a boost convertable, as others i have seen use a buck/step down convertable , so what is difference ???

Did you balance the cells before assembly? I just bought some Liitokala brand 32700's for an E200 scooter upgrade and their page says "DIY battery pack must get the cells balanced before assembly."

Can I install a regenerate system on my mid drive motor electric bike with CYC X1 Pro Gen2 5KW with 72 volts battery?? Where to purchase the system?

How apply brakes create charging to the battery? Dose your brake generate the charge or the hub motor create charge? How?

Big like for this video. Please give more info about the full charge status info. How do you know when to unplug the charger / laptop module ? And please, more info about the app who measure current on your your phone. Thanks! ☝️

Should 32V after a charge should be enough for the scooter to turn on? My scooter was very flaky (would turn off/on while riding) for a couple weeks and then just wouldn't turn on at all. Heard popping sound (likely from sparking) when it was shutting down. Replaced the controller and display panel and tried the same battery and initially (first time only) it turned on but then immediately turned off and hasn't been able to turn on since. Voltage output on the battery is 32V. Customer supports says I need to replace the battery because 32V is too low but I don't want to spend $220 only to find that something else is broken. And while this video is very cool, I don't know if I have the confidence to replace battery cells.

Out of curiosity, could you do this with front coils as well? I have a 2001 Sierra 1500 2WD and just trying to plan some things in the future. I currently have just a 1" spacer on the front coils.

You think I’d be fine running only half the cells to start a stock 9.x:1 cr v8? Needing a new battery, and I’d rather run these

Very interesting, great job. A bit beyond my time and expertise. Everyone's thoughts on buying another battery, or are they designed so poorly it will keep happening so I should just cut my losses and get a different brand scooter? Seems like there's a lot of these scooters with bad batteries.

Great vid! Anyone know WHY that last group of cells were so depleted?
