Arduino Lithium Solar Charge Controller

This is an updated version of a charge controller circuit i ve had up for a while.

Arduino lithium solar charge controller.

2 600mah 4 400mah 6 600mah lithium battery charge controller dc dc usb boosting circuit 2 5mm female panel mount plug 2 5mm male jack with wire 1n4001 diode wire building supplies. Very safe to use as it s equipped with an automatic arc fault detection that trips a circuit when it detects. Soldering ion hot glue gun drill dremel. I m wondering if i can use the trinket itself as a smart charge controller to charge and monitor the battery.

Proper buck converter topology which increases the current on the output side not just pwm. 1 charge controller as well as energy meter 2. Arduino pwm solar charge controller v 2 02 to solve this problem i made this new version charge controller so that anyone can use it without changing the hardware and software. Trying out the ltc3780 dc dc buck boost module.

The 03962a charge controller also allows charging from a 5 v cell phone charger usb mini cable. This configuration charges the battery as well as supply power to the circuit when the solar cell is producing energy. I have a trinket that i m going to be powering off of a small lithium ion battery. 5v or greater solar cell 3 7v lithium ion battery.

I was also considering adding a small solar panel to the mix and using the solar panel to charge the battery.
