I would go for the tp5000, as said in the video it is better.
I gathered more info, but I forgot
Also, you might know the company "chargery" from China,
they make cool battery stuff and they are going to roll out a 12s battery charger soon.
I might grab that instead of doing the tp5000 shit.
Mainly because I could potentially charge to 4.1v
Ill keep you updated, Bye
