Hello every body here.
I have a project in my head, need some assistance before going to proceed.

I want to use some 18650 cells and some chinese epistar 3W led chips.
LED's FW voltage is 3.2 - 3.4, the battery is 3.7 18650.
All leds will be configured as parallel as well as the batteries.
Based on the calculations I have learned here, I will need a ~ 0.57 ohm 1.5W resistor.
I'm planning to solder all batteries in parallel and use a TP4056 charger circuit to charge the batteries.
Power source will be 5V 1A charger or 5-6V 0.1 - 0.8Ah solar cells.

Any suggestions ?
Thanks.
