Re: Balancing 2 LG Chem Solar modules in series

Do balance before installing BMS . The BMS is to keep a balance pack balance. So balance first.

Re: Hunting/mountain E-Bikes

The first bike looks good. But what Samsung cells they make ones for flashlights and some for vape pipes. You want the one for vape pipes. Hartd hitting. Ask them which model Samsung cell they use. If they don't tell you it's probably run-of-the-mill Samsung cell.

Re: Battery choice for electric go-kart

You need at less 15ah or more to go around the track. You don't want to every drain them.

Re: Adding cells to a pack

24ah*5= 4800mah I guess ??? Or so.
Yes more is more speed, but more amps can give a little more speed. But not like volts.

Re: 7s15p or 3*7s5p to quickly charge?

I like big ah cells and if 45ah there are automotive grade cells in cans as 45ah and others. I mean a boat so less connections the better. Or lots of spot welds more possible for corrosion at the weld point with moisture and or salt water. I think leaf has 45ah cans ect. Or do you have access to goo...

Re: Adding cells to a pack

You are thinking of adding a 2s pack of 24ah ? For 16s 68volts fully charged ?Or you might look at putting some solder on the shunts for more amps if your battery and BMS can handle more amps.

Re: Adding cells to a pack

Open up your controller look inside do the Caps say 63 volts. If so the answer is no. You may have 75 v caps or 100 volt if so you can get away with it. by guest if you have 63 volt caps in that controller.
