Hi how's it going? I have the same frame :) I had to modify that little section underneath to allow space for my controller (100a sabvoton) Currently waiting on my rear wheel (motor) then it will be just about finished :) Are you sure a 26" wheel won't fit in the swing arm? as the advert...

I don't think it has damaged the battery's because I checked all the p group's before and after I installed the bms and they read the same, currently discharging the battery down to 72v, I think I've damaged the bms by getting the balancing wires the wrong way round, the bms heat sink was pretty...

Yes I think I'll end up replacing the bms to a Bluetooth one in the future, I will leave the pack as it is for now as it should balance itself out still with only half the bms operating and there isn't any load on the pack until my motor arrives (leaving at 72v) I was planning on building split...

I've just checked the voltage output of the charger and it's output is 84v, but the battery terminals read 76v - does the bms require 8v or so to power? My bms has b- and c- which I found the correct wiring diagram for - I checked all the connections before heat shrinking - I did however connect...

I can't open up the charger as its a seal unit, what would be the problem with the bms? Could it be a balance wire not properly connected?

What's a DMM? my charger charges at 86v 8a - I know this because when I plug in it reads 86v on the display My bms can only handle 90a though while my parallel groups can go upto 100+A but I can change the max discharge in the controller to avoid burning out the bms I also have a step down to...

Hi, I have recently built a 18650 battery pack using inr 25r 2500mah 20a discharge, the battery is a 20s (72v) 5p (100a discharge) my question is; I have just charged my battery from 72v to 75.8v and that's its maximum - my charger cut out, any idea if this is normal? I'm guessing 4v will drain...
