4 Amp 12V Lithium Battery Charger 4 Amp 14.6V Automatic Smart with Automatic BMS Activation Maintenance for Deep Cycle Battery Car Motorcycle Marine

【DC HOUSE 4A 12V Lithium Battery Charger】This is an intelligent lithium battery charger developed specifically for 12V (12.8V nominal) lithium iron phosphate batteries. The lithium battery charger is equipped with a 0V wake-up charging feature, which can effectively restore or rescue the battery cells that have been idle for a long time. The specific charging parameters are as follows: charging current is 4A, applicable to LiFePO4 series batteries with capacities ranging from 8 to 50AH. 【Convenient, Efficient, and Reliable】This lithium battery charger is equipped with an alligator clip interface, which ensures easy connection with the battery. At the same time, the lithium battery charger has successfully obtained UL1310 and CE (following EN60335 standards) double safety certification, fully guaranteeing the safety of the use process. 【Customized for lithium iron phosphate batteries】DC HOUSE brand launched a 14.6V 4A lithium battery charger, accurate service for 12V LiFePO4 battery charging needs, with the ability to fully charge such batteries to 100% of the electrical energy, compared to the non-specific charger can only achieve 90% of the full degree of performance, which significantly improves the overall performance of lithium iron phosphate batteries and to a greater extent to help extend their service life. It significantly improves the overall efficiency of the LiFePO4 battery and helps to extend its service life to a greater extent. It's an excellent lithium charger for lithium batteries. 【Efficient and fast charging lithium battery charger】With a peak output voltage of 14.6V and a maximum current strength of 4A, this lithium battery charger can charge 12V 50Ah LiFePO4 batteries with half of their capacity in just 6.5 hours, which doubles the charging speed compared with the conventional 5A charger. It is especially worth mentioning that despite the high-speed charging capability, there is no negative impact on the service life of lithium batteries. 【International certification】With a very low failure rate and excellent heat dissipation performance, the lithium battery charger incorporates three core safety protection mechanisms during operation: output short circuit defense, output voltage overrun protection, and battery isolation barrier, ensuring that you are free from any potential safety hazards during the entire charging process. Its intelligent design also realizes full automatic control of constant current (CC), constant voltage (CV) modes, and automatic switching during power failure
