Plan is to rebuild a old/bad DeWalt battery and Retrofit it with some lithium cells that I pulled from a used laptop battery
It will have a 12.6V Charger, +/-20mV Accuracy, 1A charge rate. 2 LEDs, one for Charging, one for Done
Cells will be configured as follows:2 Parallel,3 Series which will give us 12.6V at 4000mAh. Each cell is 2000mAh
Each cell in series will have to be balanced, so a balancer is needed.
This is untested thusfar, but I have built the main circuit before which does work. Everything else is extra.
To Do:
-
BOM for Charger
-
Balancer Circuitry
-
Balancer BOM
-
Build and Test Charger
-
Build and test Balancer
-
Build the actual pack
