Dear Friends,If you like the Design leave a like and show some Love.I Bought an Anglegrinder from Makita and realised that the Battery got realy Warm and didnt last at long.So i needed more Power !!For what ever Reason Makita dont offers Akkupacks 18V with 21700 Cells.There is an Design out there but that did not fit all my Machines because its to long. I redesigned everything and built in a Place for a 30x30x10 24V cooling Fan that is triggered by a cheap bimetall Thermoswitch (normaly Open Modell, NO not NC).A 24V Fan also runs with 18V, dont use 5V or 12V, it will burn down !!!After some investigation on feelwell Temp for LiOn Cells i chose a switch that activates on 45 degres celsius . you can choose also other range. Temp above 60 can be bad for the cells.I Designed this for a Cheap Battery Management PCB that also supports Cell Balancing.its Designed for cylinderhead M3 x 20 Screws and Meltinserts M3 Handling LiOn Cells is DANGEROUS !!!Dont try this if you are not sure what you are doing.
