Epoch Eco Series LiFePO4 Batteries

Reliable, maintenance-free lithium power for your marine, RV, or solar system — without breaking the budget. The Epoch Eco Series uses lithium iron phosphate (LiFePO₄) chemistry to deliver consistent deep-cycle performance, a dramatically longer lifespan than lead-acid, and significant weight savings in a familiar form factor.

Every Eco Series battery includes an advanced BMS with 20+ integrated safety protections — covering overcharge, deep discharge, overcurrent, short circuit, and high/low temperature conditions. A low-temperature charge cut-off prevents damage when charging in cold weather, and IP54-rated construction handles dust and light spray.

Both models support up to 4 batteries in series (48V) and up to 16 in parallel, making it easy to scale your bank as your needs grow. Backed by a 6-year manufacturer warranty.

Available in two sizes:

12V 100Ah (1.28 kWh) A compact, lightweight drop-in for Group 24 battery trays. At just 21 lbs, it's roughly a third the weight of an equivalent AGM. Rated for 4,500+ cycles, 100A continuous discharge, and 300A peak (5 sec). Ideal for house loads, trolling motors, electronics, and smaller solar setups.

• Group 24 dimensions: 10.25″ × 6.75″ × 9.00″
• Weight: 21 lbs
• Max parallel capacity: 20.48 kWh (16 units)

12V 314Ah (4.02 kWh) Serious capacity for larger systems. Rated for 8,000+ cycles with 250A continuous discharge and 750A peak (5 sec) — enough to run high-draw appliances, inverters, and extended off-grid stays. A true workhorse for liveaboards, large RVs, and whole-cabin solar banks.

• Dimensions: 15.5″ × 7.63″ × 10.5″ (with handles/terminals)
• Weight: 57 lbs
• Max parallel capacity: 64.3 kWh (16 units)
