Renogy Bluetooth Smart Lithium Iron Phosphate Battery Rechargeable Lithium 121000 Generator Batteries 4794328

State-of-the-art battery cells ensure a lifespan of more than 2000 cycles, 200A continuous discharge current, and a wide operating temperature range.

Upgrades to lithium seamlessly with the standard BCI group size but a greater energy density, a deeper discharge capability, a higher round-trip efficiency, and a faster charging speed.

The state-of-the-art battery management system (BMS) with high-performance dual-processors provides short circuit, over charging and over-temperature protection while maintaining a balanced voltage across all cells.

Easily connect multiple batteries in parallel with the auto-balancing function, improving the average charging efficiency for your batteries in the long term.

Monitors the battery operation status on mobile devices in real time with the built-in Bluetooth module.

DO NOT string the battery in series, ONLY connect batteries of the same manufacturer and model in parallel, DO NOT connect more than 8 batteries in parallel.

Please secure all cable connections to proper specification in order to ensure good connections between the cable lugs and the battery terminals.

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

The battery is shipped in shelf mode, Before using the battery for the first time, please activate the battery with a charge/discharge current greater than 1A and measure the terminal voltage to validate.
