EPOCH Batteries

EPOCH lithium (LiFePO4) batteries for RV, marine, and off-grid solar applications.

LiFePO4 batteries cost more upfront than lead-acid but last significantly more charge cycles and can be discharged further without damage, which usually makes them the lower total-cost option over the life of a system despite the higher purchase price.

Check that your existing charge controller and inverter are rated for lithium chemistry before switching from lead-acid — the charging profile is different, and not all older equipment supports it correctly.
