No more heavy lifting! Upgrade to Renogy's 12V 50Ah LiFePO4 Battery. Weighing in at a bit over 14 lbs, this battery can easily be carried and stored, and works perfectly as a portable power supply for family RV trips, camping trips, and more. With 2000 life cycles (80% depth of discharge), this battery is built to last.
This lithium-iron-phosphate battery is the perfect addition to any home or RV solar system. Lighter, more compact and fully compatible with our Renogy charge controllers, this 50Ah battery is ideal for your off-grid needs. You can also connect to our Battery Monitor for real-time battery usage monitoring. Don't let the adventure stop here, come explore our wide range of features today!
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.
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.
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.
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.
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℃).
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.
