Hi there, Essex. I get the cells are naff, just trying to understand why I'm not getting 4.1v when charged as 5 p pack. It's a learning curve for me, for when I get some decent cells to work with. I think I ll take a cell off and see if that charges to 4.1v. If it does what does that prove...

Hello all. I ve understood a fair bit on battery building over the last few months and when fully confident will build a decent battery. For now I have some cheap cells and experimenting with my imax b6 ( probably a clone) charger. It seems to work okay, it charges cells to 4.1 v individually...

Good advice mate

Yes, I've spent many evenings watching YouTube. Some solder, some spot weld, some use car battery s and short circuit it. YouTube has many videos on which the person hasn't a clue. Dunning Kruger effect.

Gotcha. Ok I like a challenge, but maybe building a pack isn't the route to take. I could weld the cells, I get that, but the BMS would be a problem. Let alone the fact I need to suss out the controller wiring, I don't need to complicate everything

with respect thats why i,m asking as i don,t know . i ve read up on the basics. its like is 48v battery enough to run 750w for a couple of hours.

hi there, don,t worry, i,m not rushing into anything. mechanically i,m proficient, its the electrics i will struggle with. not my bag. i ve gained alot of tips online, so i know what components i need, its just what . if say 750-1000w motor is acceptable , what battery pack for voltage/amps...

What type of BMS would you recommend. I don't know what size battery I want or need. A motor of 750 watts minimum

thanks for info. i,m a long way from getting things going with project, need advice on bms and chargers etc in due course

hello everyone, just joined. i,m building a bike from scratch, and would like to build a battery, even for experience if anything else. i,d like to know if you are supposed to check/balance each battery individually before spot welding? don,t worry, i have time on my hands!

hello all, i,m building my own bike, and wanted advice on 18650 cells. i,ve gained alot of knowledge recently, mechanically i don,t have a problem, its circuits and amps etc i,m learning about. if you buy a batch of cells, are you supposed to check/balance them individually before building the...
