Product Details
The KOMCO battery maintainer for multiple batteries charger is the premium solution for commercial fleet operators, rental depots, and golf cart maintenance hubs. This specialized model has captured massive retail volume on Amazon and top Western trading channels, rapidly becoming an essential best seller across Europe and the USA.
Managing mixed assets-like a 24V LiFePO4 golf cart alongside a 48V or 72V utility vehicle battery bank-usually requires cluttering your workshop with multiple devices. The C30 solves this entirely by consolidating those needs into one industrial-grade isolation transformer station. It delivers flawless constant current and absorption charging, shifting into a smart float charge automatically.
Technicians can adjust the rate using the Low, Medium, and High settings to achieve either precision conditioning or a safe, rapid charge up to its maximum safe current limit.
