KNACRO AC 100-240V to DC 12.6V/5A 12.6v 5a Power Supply Adapter Polymer 12V Battery Charger Transformers With a US Plug Dual IC chip SMD motherboard solutions, comprehensive intelligent protection, stoped, with short circuit, overload, over-current protection.Dual IC chip SMD motherboard solutions, comprehensive intelligent protection, stoped, with short circuit, overload, over-current protection. Charger with constant current, short circuit protection, turn lights function (No load green light, load red light , full of green). It applies to 11.1V or 12V three series of polymer lithium batteries (capacity of not less than 25AH, no more than 50AH). Charger function: In the first phase of constant current charging, LED red light indicates charging to the rated voltage into the second phase of constant voltage charging current gradually decreases when the charge current reaches the current turn lights, LED lights turn for the green light, then the battery is 90% -95%, with low current continues to charge the battery until it is full.
