Charger Upgrade
I have been using the Yonii Q2 charger for a few months now to charge my Convoy batts. The problem I have with the unit is that the fit is quite tight for 21700 (unprotected flat tops) and I worry that it'll damage the battery wrapping over time. I saw people recommending the Vapcell S4 Plus so I decided to get one and it just arrived today. Quite overkill imo but I hope this can last a long time.
