12V 320Ah LiFePO4 Battery

The 12V 320Ah LiFePO4 Battery is a 4,096 watt-hour block with a 200-amp continuous rating, on M8 terminals, rated IP65. It is a large house bank for a boat-house or an off-grid villa.

A Small-Home Bank

4 kilowatt-hours a day

4,096 watt-hours run a small home or a large boat through a day: refrigeration, lighting, water systems, electronics and a 2,000-watt inverter for cooking and tools. The depth of discharge stays shallow on that load. At that shallow depth the 4,000-cycle rating lasts well over a decade.

Off-Grid Villa

Solar and bank

An off-grid villa pairs the bank with a solar array of 600 to 1,000 watts and refills a day’s use in good sun. Blocks parallel for more storage as the house grows. A 12-volt bank this size feeds a 12-volt inverter direct without a higher-voltage conversion.

Against Lead

Store and weight

Reaching 320Ah in lead takes four heavy batteries near 90 kilograms for about 160 usable amp-hours. This block gives the full 320 amp-hours at 33 kilograms.

System Voltage

12, 24 or 48

A house this size can run at 12, 24 or 48 volts. Staying at 12 volts keeps the wiring simple and the inverter and controller common, at the cost of heavier cable for the current. Four of these blocks in series reach 48 volts for a house that wants the lighter wiring of a high-voltage bank. The single 12-volt block suits a boat-house or a cabin already on 12-volt systems.

Charging

Charge at 14.6 volts from a lithium charger or a villa-sized LFP solar controller. Add a block in parallel for more storage, matched at rest first.
