2 X 300AH LiFePO4 (LITHIUM) BATTERIES, EACH WITH ITS BMS ON TOP, INSTALLED IN A STRONG AND SECUREL LOCATION, STRAPPED DOWN AND BACK TO THE BULKHEAD. THERE IS A VENTED SEPARATER BETWEEN THEM.
THESE ARE LOCATED ON THE RIGHT HAND SIDE, ALONG WITH ASSOCIATED ELECTRONICS, AS PART OF THE WEIGHT BALANCE OF THE VEHICLE - THE FRIDGE IS ON THE LEFT, AND IS (ALWAYS) THE SINGLE BIGGEST MASS ITEM, SO A LOT OF GEAR NEEDS TO BE LOCATED ON THE OPPOSITE SIDE. OTHER ITEMS ON THE RIGHT ARE THE GALLEY (INCLUDING FOOD MASS), AND HOT WATER SYSTEM.
