so today will supposedly stress testing the v2 i kept it on idle for 20 mins and it blacked out after that so i immediately unplugged everything and i tried charging the battery using tp4-56 module but it also got very hot so i removed all the battery wires and turns out the tp4056 module was fried because of overdischarge (i was using 3.7 v lipo battery with v2 instead of 3.7 li ion 18650 in the v1). After some diagnostics i found out that it occurred because of thermal problems so for now i have to redesign the case to fit a 18650 because it is more reliable. Also added some zipties
