Hi Folks
I'm attempting to make a battery for my e-bike. I have 2 spare 48v (54.4v max) 12.5AH batteries and want to make a 72v or 80v max - haven't decide which yet - controller can handle 90v max.
In total I have 130x18650s from the two 48v packs - don't know what spec they are yet - havn't got that far.
I was thinking about making 4 x 5S 6P batteries, that I could serial together. The reason for doing this is cheaper bms and charge units, simpler to make and much more flexible mounting options on my ebike e.t.c.
Has anybody done this?
What are the pros and cons of doing it this way?
or is this just a really dumb idea?
thanks!
