4 Times Longer Lifespan

With superior lithium-iron-phosphate technology and sealed design, this battery offers a superior cycle life with 2000 cycles at 80% DOD. This is approximately 4 times longer lasting than lead-acid batteries.

Powerful Output

Renogy 12V 50Ah LiFePO4 battery provides a maximum of 640Wh power output, which is 2 to 3 times more powerful comparing to most lead-acid batteries in the same size.

Protected Charging & Discharging

The intelligent built-in BMS circuit ensures safe charging and discharging process by protecting the battery from over-charge, over-discharge, over-current, high temperature, and short circuiting. The battery provides a maximum of 50Ah continuous discharge current to power most home appliances. The superior lithium-iron-phosphate technology ensures stable battery capacity and performance even under extreme temperatures from -4℉ (-20℃) to 140℉ (60℃).

Longer Shelf Life

With a low 3% self-discharge rate per month (at 77℉/25℃), even if the battery is stored in the garage since your last camping trip a year ago, it’ll still have over two-thirds of its charge before you head out.

Safe and Reliable

The built-in Battery Management System (BMS) provides over-charge/discharge, over-current, high temperatures, and short-circuiting protection. The fully-sealed housing prevents acid leakage and corrosion and ensures simple maintenance.

50% Lighter

Weighing only 14.7 lbs, this LiFePO4 battery is smaller, lighter, and at the same time delivers more power than conventional lead-acid batteries. The reduced weight makes it easy to carry and install.

Auto-Balancing Function

Thanks to the excellent auto-balancing function, you can use identical batteries to connect in parallel to extend power capacity safely. Up to 8 batteries can be connected in parallel. Please note that series connection is not allowed.

Extremely Robust

Our battery provides a continuous 50Ah discharge current and 640Wh max power to charge most home appliances. It is tolerant to extreme temperatures, offering stable discharge performance between -4℉ ~ 140℉ (-20℃ ~ 60℃).

Real-Time Accurate Monitoring

Renogy’s Battery Monitor is fully compatible with this battery. This external device allows you to monitor the charging status of your LiFePO4 battery in real-time with a large display screen.

The Battery Monitor is sold separately at the Renogy store. SKU: RBM500

  • If the battery’s Battery Management System (BMS) is activated and the battery voltage shows 0V, you must use a compatible Li charger to reactivate this battery.
  • Make sure to screw in the battery terminals tightly. Loose battery terminals will cause heat build-up and cause damage to the battery.
  • DO NOT string these batteries in series. They are made ONLY for wiring in parallel using identical batteries.
