Re: [electricboats] CAN to NMEA2000 motor data

Hello Thomas.     4p4s.  Or 16 cells per 12 v 360 ah battery pack.    4 packs in series yield. 48 v. 360ah.  I hope this helps.  Thank you. Kind regards Larry Schmitz

LARRY: Something seems amiss with your description.  You describe having built four, 12v batteries with 3.2v 90Ah cells.  So those cells must be connected in series to achieve the 12v, and yielding 90Ah capacity.  Then you say you connected those four 12v packs in series to achieve 48v, with one BMS for the whole system.  This sounds similar to the system I put together to drive my Thunderstruck Motors 10Kw sailboat kit.  But because your batteries are all connected into a single series to yield 48v, I believe the capacity would still be 90Ah and not the 360Ah you suggest.  The way I'm understanding what you've put together, your system is in fact a 16s1p battery pack, not a 4s4p pack.  A 4s4p pack would have 360Ah, but at 12 volts.
