Hello Mr. Mooch.
I am French (I use Google translation).
I have a question for you and I would be very happy if you can answer me.
I have to go hiking, I should recharge my battery quickly in cottages (4 amp xtar slim4)
Can I use 18650 vtc6s that have a fast charge of 5 amps where is it safer to use 21700 40Ts that have a fast charge of 6 amps.
