Reliable LiFePO4 Power for Your Off-Grid Setup

The Renogy 12V 50Ah LiFePO4 battery delivers 640Wh of field-tested energy storage in a 14.7 lb package — half the weight of a comparable lead-acid unit. With 2000 cycles at 80% DOD, this battery is built-to-survive daily off-grid use for roughly five years. A built-in BMS handles over-charge, over-discharge, over-current, high temperature, and short-circuit protection, while the fully-sealed housing eliminates acid leakage and corrosion concerns entirely.

Four Years of Runtime Your Lead-Acid Battery Cannot Deliver

Four Years of Runtime Your Lead-Acid Battery Cannot Deliver

Lead-acid batteries are the reason people think off-grid power is unreliable. They sulfate, they leak, they die after 500 cycles while you are still paying for them. The Renogy 12V 50Ah LiFePO4 battery eliminates that cycle entirely. At 2000 cycles and 80% DOD, this unit delivers four times the lifespan of any lead-acid equivalent in the same form factor. Off Grid Vault vets every battery we carry against real-world performance data — not datasheet marketing. If it cannot survive the kind of daily cycling an off-grid setup demands, it does not make the cut. This one does.

640Wh Output in a 14.7 lb Package You Can Actually Move

640Wh Output in a 14.7 lb Package You Can Actually Move

At 14.7 lbs, this LiFePO4 battery weighs half what a comparable lead-acid unit does — and delivers two to three times the usable power. That 640Wh capacity means running lights, a CPAP machine, communications gear, or small appliances without the back-breaking weight of traditional batteries. The fully-sealed housing eliminates acid leakage and corrosion, so you can mount it in any orientation without maintenance headaches. Whether it lives in your cabin battery bank, rides in the back of your truck, or powers a remote communications post, the reduced weight and zero-maintenance design make deployment straightforward.

Built-In BMS Keeps Your Battery Bank Safe Through Every Condition

Built-In BMS Keeps Your Battery Bank Safe Through Every Condition

The integrated Battery Management System monitors over-charge, over-discharge, over-current, high temperature, and short-circuit events in real time. This is not an add-on module — it is factory-installed and calibrated to the cell chemistry. The lithium-iron-phosphate technology maintains stable capacity from -4°F to 140°F, so winter cabin mornings and summer heat waves do not degrade your stored energy. When you pair this battery into a multi-unit bank, that BMS protection scales with every unit you add. No external charge controllers required for basic safety — the battery looks after itself so you can focus on your system, not on babysitting individual cells.

Compatibility Check

Confirm this battery matches your system before you buy.
