And I am thinking instead of type c i should use round pin connector and a charger which turns off when charging is full what do you guys say ?

Or another way is use two lithium cells in parallel then use a step up convert 3.7 to 12v dc

And for charging use tp4056 which has all protection in it

Update:

 

I will be using 3s in series then use bms for battery protection

And for charging I will use ddtccrub 3s‑3a module 

 

Everything looks fine ?
