Renogy 48V Battery Rechargeable Lithium 121000 Generator Batteries 4794321

Renogy’s latest 48V battery delivers a breakthrough in quality by offering an exceptional lifespan of more than 4500 cycles (reducing to 80% capacity after 4500 cycles), a 50A maximum discharge current, and most importantly, an extensive five year warranty.

The intelligent self-heating function will start operating automatically once the battery’s core temperature drops below 41°F (5°C), effortlessly keeping your battery charged in cold environments.

The upgraded battery management system (BMS) with high performance dual-processors provide load fluctuation resistance while maintaining balanced voltage across all cells.

The lithium battery has low temperature charging and discharging protection function, When the temperature is below 0℃, it will stop charging, When the temperature is below -20℃, it will stop discharging.

Easily connect multiple batteries in parallel with the auto-balancing function to improve the average charging efficiency of your batteries over extended use.

The normal operation of the self-heating function requires a stable charge current greater than 3A

Please secure all cable connections to the proper specification in order to ensure good contact between the cable lugs and the terminals, Over-tightening cable connections can cause terminal breakage and loose cable connections can cause terminal meltdown or fire.

DO NOT string the battery in series, ONLY connect batteries of the same manufacturer and model in parallel.

Please avoid too high a voltage difference between paralleled batteries, despite the auto-balancing function, to avoid triggering the over-current protection.
