Hi fellow RCIndians,
Damaged lipos have often some cells in working condition .Solder as many cells as you need /have to make a power back up for 5V DC devices (Mobile chargers, Modems, Leds ..etc) .
Since all your individual cells won't have same voltage please
do not directly short circuit cells in parallel while soldering.
Use a resister or a filament bulb to short the cells and voltages should be Equal. Electronics Circuits and Switches are not modified and are used from a Single module .
f4k3url/10GxR0s any generic/chinese power bank should do the job.
Any power bank will do. Just remove the intenal battery (so it doesn't mattery which one u buy 1000mah or 5000mah ) and solder connections to lipo.
config:
Battery:
1S3P
2650*3 ~ 8000mAh
1 USB out (max 800mA)
1 Torch (4 leds)
1 UV currency detector
Charging is done via the provided 2mm nokia pin with max 300ma(although lipo can handle more ,charging ckt will fry if current goes above 700ma)
