Our take on the PowerTex 12V 35Ah LiFePO4 Lithium Iron Phosphate Battery

The PowerTex 12V 35Ah is a small-format lithium iron phosphate deep-cycle battery with a built-in battery management system. The BMS handles fault protection and cell balancing, and the impact-resistant case suits mobile and outdoor installs. It is aimed at RV, marine, trolling motor, scooter, kids ride-on and small solar or backup setups, and it can be wired in series for higher voltage or in parallel for more capacity. Against lead-acid batteries of similar capacity it is lighter and needs no maintenance, but it holds less energy than the larger 100Ah LiFePO4 packs many off-grid users choose. Buyers rate it highly and report it works as advertised and lasts, though some struggle to find a battery box that fits its dimensions.

About the PowerTex 12V 35Ah LiFePO4 Lithium Iron Phosphate Battery

This is a 12V, 35Ah lithium iron phosphate (LiFePO4) deep cycle battery in a compact, small-format size. It has a rugged, impact-resistant case.

A built-in battery management system (BMS) protects against faults and balances the cells. The battery is designed for fast charging and high heat tolerance.

It can be wired in series for more voltage or in parallel for more capacity, so you can build larger battery banks. It suits RVs, marine use, solar and off-grid systems, backup power, trolling motors, kids' ride-on vehicles, scooters and DIY solar projects.

Questions and answers

Can I wire two of these in series for 24V?
Yes. The battery supports series connections for higher voltage and parallel connections for more capacity, so two in series give 24V at 35Ah.
Do I need a special charger?
Yes. Use a charger with a LiFePO4 profile, typically 14.4 to 14.6V absorption. A lead-acid charger can leave it undercharged or trip the BMS.
How does it compare with a 100Ah LiFePO4 battery?
It stores about a third of the energy in a much smaller, lighter case. Choose it for scooters, trolling motors and small backup loads; choose 100Ah for serious off-grid capacity.
What can it run?
Small loads: trolling motors, scooters, kids ride-on cars, lights, pumps and small solar or backup systems. Check your device's current draw against the BMS limit.
Is it safe to mount inside an RV or boat?
LiFePO4 chemistry is stable and the built-in BMS protects against faults. Mount it securely in a ventilated spot and keep terminals covered.
Does it come with a charger or cables?
No. It is sold as the battery alone, so plan on a compatible LiFePO4 charger and your own cabling.
Where is the PowerTex 12V 35Ah LiFePO4 Lithium Iron Phosphate Battery cheapest?
