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.
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.
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.
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
