Benefits Of Delong lithium Battery Packs
Enhancing Performance with Efficient Lithium Batteries
The Delong lithium battery, with 6,500 cycles, is an excellent alternative to lead-acid batteries! It has a high energy density and weighs only a quarter of a lead-acid battery, yet it delivers 200% more energy. Allowing you to fully utilize its capacity with almost no maintenance required, this lithium battery is the king in deep cycle applications such as RVs, trolling motors, home solar systems, UPS, and more.
Ensuring Safety with High-Performance Battery Technology
To give you greater peace of mind when using Delong lithium batteries, we have equipped them with an intelligent Battery Management System (BMS). The BMS can automatically cut off power in the event of any battery abnormalities, preventing issues such as overcharging, over-discharging, and overheating, thereby ensuring electrical safety.
