2.56kWh LiFePO4 Battery Pack 12.8V — Deep Cycle Solar Storage, 6000+ Cycles
2.56kWh LiFePO4 Battery Pack 12.8V — Deep Cycle Solar Storage, 6000+ Cycles
Double the capacity of the 100 Ah pack in a similar footprint, the 200 Ah version suits users whose 12 V loads run longer — a night of lighting, a fridge on a boat, or a trolling motor worked hard through a day.

Questions buyers ask
How much usable energy at 80 % DoD?
About 2 kWh usable from the 2.56 kWh nominal capacity — enough for a 12 V fridge drawing 40 W to run for roughly two days without recharging.
Can I parallel two for 400 Ah?
Yes, with matched units. Keep the cables equal length and check that your charger can deliver the combined recommended current of 100 A.

Frequently Asked Questions
What is a LiFePO4 battery?
Lithium iron phosphate chemistry that offers long cycle life, thermal stability, and safe deep discharge compared with older battery types.
How long does it last?
LiFePO4 packs typically deliver thousands of charge cycles at 80% depth of discharge, which means years of daily use.
Can I expand capacity later?
Many IPV ESSA systems support parallel battery expansion; check the model manual for the maximum number of units.
Where should I install it?
In a ventilated, dry location away from direct heat and moisture, as with any electrical storage equipment.
