12V LiFePO4 Batteries

SOK 12V LiFePO4 batteries are the modern replacement for 12V deep-cycle lead-acid AGM and gel batteries in RV, marine, van, and small off-grid solar systems. Available from 100Ah to 314Ah in sealed marine-grade plastic, user-serviceable metal, or premium aluminum housings — with self-heating models for cold-weather climates and Victron-compatible variants for serious DC system builds.

Who This Is For

RV owners replacing 100-300Ah AGM banks, vanlife builders, marine boaters and trolling-motor setups, small off-grid cabins, and overlanders running fridge + lighting + accessories.

Key Specs to Look For

• 100Ah — drop-in lead-acid replacement, weekend RV/marine
• 206Ah — extended RV use, dual-battery vans
• 280Ah — full-time vanlife, heavy DC load
• 314Ah — biggest 12V available, Victron-compatible
• Sealed plastic (P suffix): marine-grade IP rating, sealed for water exposure
• Metal (no P): user-serviceable case, easier cell-level inspection
• Heated (H or PH suffix): built-in low-temp heater for sub-freezing operation

Why Choose SOK LiFePO4

12V LiFePO4 from SOK runs at full 100% capacity from 80% state of charge down to 20% — versus lead-acid which derates after 50%. That doubles usable capacity per dollar. Pair with a Victron MultiPlus inverter-charger and SmartShunt for a complete plug-and-play DC system.

Frequently Asked Questions

What's the difference between 100P and 100H?
P is Plastic, sealed marine-grade with Bluetooth BMS. H is Metal, user-serviceable, with built-in self-heating for cold weather. Pick based on your environment.

Can I replace my AGM batteries with SOK LiFePO4?
Yes — most 12V AGM banks can be replaced 1:1 with SOK LiFePO4. You'll need to verify your charger profile supports LiFePO4 voltage curves (most modern Victron, Renogy, and Magnum chargers do).

Do I need a battery monitor?
Strongly recommended. A Victron SmartShunt 500A or similar gives you accurate state-of-charge reporting that the BMS alone can't provide at a system level.
