Read page 8 of this forum to get a ideaI bought 4 boxes of samsung 50s 21700 5000mah 25a battery to make either a 2ps13 @480wH or 3ps13 @720 wH in frame and then an external battery for longer weekend rides. I thought i saw 39 cell diy packs of 21700 that fit the frame, and figured id git it a try. a 720Wh 36v battery pack would take 40 cells, and i saw somewhere that people can take advantage of more voltage at the end of a 48v pack on 43v firmware or something like that... I want the internal battery pack to be good for 1.5-2.5 hours, and be able to get double that for weekend adventures.
for bms i bought a daly 60A 48V
also i speced my m820 out as 48v... but what does that mean? Is it a physical comopnent configuration or just firmware. If i abandon the 48v can i flash with besst and change to 43 or 36?
thanks
