Rank #3 in Best LiFePO4 Battery 2026: 10 Ranked, and Where the Spec Sheets Slip
HumsiENK 12V 150Ah LiFePO4 Battery, Group 31
Price and rating as shown on Amazon when we collected them. Both change.
The HumsiENK 12V 150Ah LiFePO4 is third in this guide. It is a 12.8V, 150Ah lithium leisure battery in a Group 31 case, sold with a Bluetooth app that reports voltage, current, state of charge, temperature and cycle count. It costs £189.99 and carries 4.4 stars from 106 ratings — a spread that includes 66 five-star ratings and 7 one-star ones.
What earns it a place here is a number that does not match itself. The bullet points advertise an "integrated 110A Battery Management System", while the spec table's Amperage field reads 100 Amps. The listing carries both figures and reconciles neither. The headline capacity, at least, holds up: 12.8V × 150Ah is 1,920Wh, exactly what the product name claims. At £189.99 for those 1,920Wh the battery works out at roughly £99 per kWh, below the £101.55/kWh of the Rvpozwer 12V 100Ah and the £139.65/kWh of the ECO-WORTHY 48V 100Ah noted elsewhere in this guide. The warranty is a separate matter: 5 years in the spec table, against bullets promising "nearly 10 years" of service. Everything on this page comes from the Amazon listing as published, not from any testing we carried out.

How many cycles does the HumsiENK 12V 150Ah last?
