Long-term Solution

Siekon LiFePO4 battery offers 4000~15000 cycles, with 4000 cycles at 100% DOD, 6000 cycles at 80% DOD, and 15000 cycles at 60% DOD. LiFePO4 batteries have a lifespan that is 10X longer than lead-acid batteries (200-500 cycles), making them a cost-effective investment and an intelligent long-term solution.

EV Grade Battery Cells

Siekon 12V 100Ah LiFePO4 Battery is powered by four EV Grade LiFePO4 cells, offering higher energy density, more stable performance, and greater power. It excels in high temperatures, delivers high power output, and has a low self-discharge rate. Compared to lead-acid batteries, this battery provides 2X available capacity and can be charged and discharged repeatedly without experiencing memory effects.

Upgraded 100A BMS

The built-in 100A Battery Management System (BMS) prevents overcharging, over-discharging, excessive current, and short circuits. Its low self-discharge rate and robust protection against dust, shocks, and crushing ensure enhanced performance and a longer lifespan. The ideal discharge temperature range is -4℉ to 131℉ for both indoor and outdoor applications.

Max.20.48kWh Energy Storage

Supports up to 4 parallel and 4 series connections, providing ample power for RVs, trailers, large homes, boat trailer motors, solar systems, camping, trolling motors, home alarm systems, and outdoor activities. This battery is not intended to be used to start any devices, please DO NOT use it as a starting battery.
