I have been lurking in the forums for quite a while now. Recently I have begun purchasing all of the parts required for my mountainboard. I am stuck on making a decision for my BMS system and was wondering what you guys think.
The planned battery will be 10s10p using Samsung 30q cells. I will be using 10mmx.2mm nickel strips to wire the battery together(using 10 strips parallel to handle the amperage, and 10awg wire on the entire positive and negative side). I am also planning on using the BMS for charging/balancing only, and bypassing it for discharging. I understand the risk with this, however I am using a the dual vesc 6.6 and will monitor the voltage properly. (as a side note, if there are any problems with this setup let me know. I have heard that nickel strips are not the best with this many p groups, however I will be using 10 parallel strips to handle the current which should be within spec)
The question is, can I use a single BMS to manage this many cells without problems, or should I create two 10s5p packs which each have their own BMS in parallel and have them share the charging port. I am currently under the impression that 1 BMS which is bypassed will fulfill all my needs as I can charge at 8A max(though I will use 4A or 6A), and will balance the cells if given the time(I charge overnight so Ill have the time)
The BMS in question will be this one
TL;DR: do you guys recommend I use one or two BMS chips in a 10s10p BMS bypassed pack?
