Rank #10 in Best LiFePO4 Battery 2026: 10 Ranked, and Where the Spec Sheets Slip
Rvpozwer 12V 100Ah LiFePO4 Battery, Low-Temp
Price and rating as shown on Amazon when we collected them. Both change.
The Rvpozwer RXA1-1 is a 12V 100Ah LiFePO4 lithium battery with low-temperature protection, priced at £129.99 and sitting tenth in this guide of ten. It carries 4.2 out of 5 from 169 customer reviews on Amazon. It is not the biggest battery here and not the cheapest in headline price, but on the listing's own numbers it is the cheapest per unit of energy: 12.8 V x 100 Ah is 1,280 Wh, and £129.99 divided by 1.28 kWh is £101.55 per kWh, the lowest of the ten in this guide.
The listing disagrees with itself in three places worth knowing about. The first bullet calls the integrated BMS 100A and then, in the same bullet, says the battery's current "can reach up to 120A". The third bullet gives two different cycle figures — 18,000 charge cycles, and 80% capacity retained after 5,000 deep cycles. And the technical field "Battery Cell Type" reads "Lithium Metal", while the bullets describe the cells as LiFePO4 (lithium iron phosphate), which is not the same chemistry. Everything on this page comes from the Amazon listing and its customer reviews; none of it comes from testing we carried out ourselves.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“So far has worked well and holds the charge well. All my devices run off one 100AH battery with no problem. As I increase my solar setup I will invest in another battery as will need more capacity. Well worth the money if setting up a simple solar system”
Verified purchase“Arrived in good time, much lighter battery than the one we had in our solar generator. Battery was fully charged... THANK YOU!”
