    Making a 1 Watt Solar Array.

    yes it will not fully charge but more than sufficient for my application. i am using for deem lantern.so i am using low power LED with resistance in series so it is glowing for 7 to 8 hrsnow i just want to ask you is it want any resistance to protect my lithium polymer battery.my battery have inbuilt PCM/PCB protection but then also it is expands its size.

    Dear Sir,I am had done the small lanterns 20nos for my window.i am using that form 7to8months. now out of 20 5 has battery size expands & they cant stay for half hri had use 5volt/80mA solar panel & battery lithium polymer 3..7volt/400mA with one diode only i am connected on output 3LEDs 3volt/20mA with 72ohms of resistor.can you please help me to how stop to expand this battery problem?

    thanks for replay. i just want to know through 3V to 5V boost converter can we use total charge from 2.2Ah battery to charge our mobile?

    Dear friend,Good work. i just want to know1) the life of solar panel what you had used.this is epoxy mini solar panel. 2) also some the li-ion 18650 battery are available with PCM/PCB (for cutoff for low discharge & overcharge protection circuitry ) then we don't want to use tp4056.attached image shows li-ion with PCM/PCB

    Why you use inductor in instead of resistor. for apporse current we can also use resistor

    Dear friend i am ninad i am also from Maharashtra.i found substitute for this ic using transistor. Please contact mi my email id is ninadt23@gmail.comto share knowledge to both of us

    Dear friend,i also made some lantern based on same consent. but instead of using this IC i use transistor. i don't know its drawback please mail me then i can share my product details with you. my email id is ninadt23@gmail.complease check my product photos
