I was thinking that I would make up the cable myself with a dsub male from the balancer using the original wire from that. 100 balance modules claim that thier wire cannot be substituted for some reason? And after reading the previous post using ptfe or other high temp wire inside the case to...

Was wondering if a dsub 15 would work. It seems they are more than capable of handling 36v 1a. Then a case of just wiring the pins needed. You can get waterproof covers for them also.

Yes I have flown RC too. I just seems to be a reasonable and feasible way to do Ebike packs too. Especially given the cost of these things! I would imagine for safetys sake too.

I was wondering if anybody has added balance ports on the exterior of battery packs. It would be good to be able to swap a Active 100balance module to various packs to save opening the packs up?

Oh I meant to say that there is a very experienced ebike builder near to my house who I got to check out my work.

I watched lots of battery builds on youtube. And wanted to know what was going into my pack. I insisted on 0.3mm pure nickle strip for the cell groupings as I know some are using 0.15mm nickle plated steel. It is indeed a first build and my previous interest in building radio control fixed...

It was after reading something online. But, I'll give them the benefit of the doubt and use along with my own build battery. It is finished now and working fine.

I will upload pics a little later. I just got carried away tbh. I was needing a project. I am ex engineer (Machine shop) and not happy unless I have some kind of headache to work on. I have dabbled in electronics to some extent. I was frustrated at the fact that it seems like if you want a...

Thanks for letting me join here. I just converted my mountain bike with Bafang 36v 350 W Mid Drive kit. I used a 17.5ah cheap chinese cell battery from amazon but being a tinkerer I soon wanted more range, and after learning about cheap chinese cells I wanted something better. I opted for a 90...
