I have almost completed my portable raspberry pi, but i have some troubles with batteries.
I got two cheap romoss 5V 10200 mAh battery pack which worked perfectly until I burn the embedded electronics :0. Now I have two parallel mount of 5 li-ion elements without any surcharge or discharge protection.
Do you have some advices on simple circuits or chips to drive those li-ion elements?
My final goal is to feed a boost converter with the two pack in series in order to get my 12 V screen and my 5V usb hub work.
