A 100 AH 24 volt battery and a 200 AH 12 volt battery hold the same amount of power. Assuming they are using 100 AH cells, the 12 volt will have 2 sets of 4 in series in the case that are then in parallel and the 24 volt version will have all 8 in series. You could literally open the case and change a 12 to a 24 volt or back again, BMS issues aside. Don’t forget the lithium batteries in a standard-size case may not be using all the real estate inside that case either, it isn’t like lead-acid where a certain capacity means a certain size.

Two of them means a dead BMS only takes half the bank offline, not 100% of your power. 2. They have heaters for the very rare times the cabin might be below freezing. 3. They have Bluetooth for access to the BMS. 4. I saved the best for last, if the BMS craps out or you just want a better one, just open it up and replace it! This is NOT possible with most batteries unless you cut them apart. 5. See 4, a dead cell can be replaced. Joe Della Barba Coquina C&C 35 MK I Kent Island MD USA
