A 12.8V 200Ah lithium iron phosphate (LiFePO4) battery pack rated at 2.56 kWh, built for solar storage, off-grid cabins, RVs and backup power. It can be wired in series for 24V or 48V banks and in parallel for more capacity. At $294.99 at Amazon as of November 5, 2026, it is priced at roughly $1.15 per watt-hour, which is low for a 200Ah LiFePO4 pack and well below the $400 to $600 many name-brand 200Ah units cost.

Pros
  • 2.56 kWh of usable storage in one 12V pack
  • Series wiring supports 24V and 48V systems
  • LiFePO4 chemistry is safer and longer-lived than lead-acid
  • Low price per watt-hour at $294.99
  • No maintenance and no acid fumes
Cons
  • No brand or model name given, so support and warranty are unclear

Questions and answers

Is $294.99 a good price for a 12V 200Ah LiFePO4 battery?
Yes. That works out to about $1.15 per watt-hour, which is at the low end for a 200Ah LiFePO4 pack. Comparable name-brand 200Ah batteries often sell for $400 to $600.
Can I wire these in series for 48V?
Yes. The listing supports series connection at 12V, 24V and 48V with 50Ah to 200Ah units. Use identical batteries of the same age and charge state, and a balancer for 48V banks.
Can it charge below freezing?
No. The stated charge range is 0 to 40°C (32 to 104°F). Charging below 0°C can damage a LiFePO4 cell, so use a controller with low-temperature cutoff in cold climates.
What can a 2.56 kWh battery run?
It can run a small fridge, lights, fans and device charging for a day or more, or a 1,000W load for about two hours. Pair several in parallel for larger loads.
What charger or solar controller do I need?
Use a charger or MPPT controller with a LiFePO4 profile, typically 14.2 to 14.6V absorption. A lead-acid-only charger will not fully charge it.
What is in the box?
The listing does not state the box contents. Expect the battery itself; confirm whether terminals, bolts or a manual are included before ordering.
Where is the 12.8v 200Ah Lithium Ion Battery 12V 200Ah 2.56KWh Solar Systems LiFePO4 Battery Pack cheapest?

Where can I buy the 12.8v 200Ah Lithium Ion Battery 12V 200Ah 2.56KWh Solar Systems LiFePO4 Battery Pack?
