DC/DC lithium battery charger 14.6V, 30A, 400W, IP68

Product overview
WG-12C400L is a high-performance DC-DC charger specially designed for charging lithium iron phosphate (LiFePO₄) and lithium manganese (LiMn₂O₄) batteries. Thanks to a wide input voltage range of 10-36 VDC and a power of up to 400 W, it provides stable and efficient charging, especially in field applications where standard mains power is not available. Intelligent multi-stage charging in constant current (CC) mode until the target voltage of 14.6V is reached and the current is then automatically reduced to 10%, ensuring safe and gentle battery care, without the risk of overcharging or damage.
