LiTime 12V 40A DC to DC Battery Charger


COMPATIBILITY Knob operation makes it convenient to quickly select the type of battery that needs to be charged. The output current of the charger is 40A, with high efficiency and adaptability to larger capacity battery packs; There is a low current port that can limit the output current to 20A. There are two charging and discharging current options, 20A and 40A, which are convenient for use in multiple scenarios. 

SMART MULTI-STAGE CHARGING The 12V 40A DC to DC smart charger changes different charge modes to match your battery type. For LiFePO4 Battery it will charge in 2-step mode (CC, CV), for Lead Acid Battery it will charge by 3-stage charging (Bulk, Absorption, and Float). It can optimize the charging efficiency of different types of batteries and extend their service life. It also can wake up your lithium battery after BMS protection. 

VARIOUS PROTECTION SAFETY This LiTime battery charger with high-quality offers over-voltage protection, low-voltage protection, over-temperature protection, short circuit protection, and output reverse polarity protection to ensure operation safety. It also isolates the input and output to prevent voltage transfer errors and interference with home battery charging.

WIDELY USED The compact and robust design of LiTime 12V 40A DC to DC charger makes it suitable for RVs, commercial vehicles, and many more applications. The output end can not only be connected to a service battery but also be directly used with a DC load.
