OMNI LED Flashlight need to replace the old 4v sealed lead acid battery to 2 parallel 18650 battery and with TP4056 lithium charger to charge the battery
Material :
-OMNI LED Flashlight (Model: AEL-100)
-TP4056 lithium charger with over-discharge protection
-2pc 18650 Battery (any capacity the larger the better)
-Tiny wire
I use the board of the OMNI LED Flashlight (Model: AEL-100), just modify it to give power to the TP4056 charger, and connecting TP4056 charger to the LED flashlight board. The board of the LED Flashlight is accepting 3-5v from a battery so its safe to use 18650 battery with 3-4.2 volts, I test the voltage-current board to the LED array, it just 3v for high and 2.8v for low.
