Hopefully I format this well. I’m in the middle of the planning/buying stage for my first build; had to jump on some of the Black Friday/Cyber Monday Deals. So, here’s my (admittedly disgusting) parts list so far:Original spreadsheet
I believe I’m just missing some electronics. I did jump on the 6355’s that were on sale over the 6374’s even though my campus is pretty hilly - do you guy think 2 x 6355 @ 10s, 36:14 gearing will give me decent enough power? I don’t think I could’ve justified the jump in price for 6374’s.
What I’m missing is BMS + Switch and a charger. I think I’m set on getting a cheap BMS to handle charging alone and an additional anti-spark switch for the FOCBOX’s, e.g.:
Opinions and/or suggestions? Honestly I’ve had a hell of a time trying to find BMS’s, but I’m trying to avoid group buys.
Finally, the charger - this is probably a stupid question, but what voltage am I looking at for a charger? I’m pretty sure 4.2V was the nominal voltage for the 30Q’s, so is it as easy as 10 x 4.2 = 42V for a charger? Any suggestions for websites I can look at or a specific charger? Another potentially stupid question, but does/can the BMS handle cutting the charger off once all the cells are at nominal voltage? I just realized I had no idea what circuitry handled that, unless there’s something inside chargers themselves that does it?
Anything else I’ve overlooked? Any suggestions, tips, pointers, etc. etc.? I appreciate any help I can get with this since it’s my first build and goodness knows I’m gonna screw at least a couple things up!
