LiFePO₄ across 10 × 12V WattCycle 100Ah bluetooth (internal BMS) batteries. 9 are in the main house bank, one is dedicated to the Electroscan macerator ("electropooper").
Three different capacity numbers are all valid for different things:
-
House bank nominal: ~10.8 kWh (9 × 100Ah × 12V)
-
Total system nominal: ~12 kWh (includes the 10th battery dedicated to the Electroscan)
-
Actual realized: ~11.5 kWh per BMSes when fully charged — not all batteries reach a true 100Ah. This is the right figure for power-budget math (see Jimmy-Shower).
-
Main house bank is in starboard salon (relocated from lazarette — see Interior for rationale & layout)
-
Main house battery box is King StarBoard
A single AGM starter battery in a battery box under the engine bed (Interstate 27M-XHD, 100Ah).
- Balmar 120A with MC-614 external regulator (still installed)
- Serpentine belt conversion on the Yanmar 4JH2E
- Currently only feeds the starter battery (oversized for a single AGM)
Reset the Balmar regulator and add a Victron DC-DC charger to feed the house bank.
