  1. 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.
    Thank you
