Review on Godox V860II S Speedlite Compatible HVL F60M by Steve Stone

I have bought several Godox flashes in the past. 2x TT860II (Li-Ion), TT685s, (AA), TT80 (Li-Ion). The flash itself works great. First and foremost, lithium-ion batteries are great. The charging time is fantastic and they last all day. BUT after about a year the cells inside the battery case start to swell. After that, you CANNOT insert or remove batteries in the flash's battery compartment. It also comes from the VB-18 (upgraded battery) that I bought later. I can't be the only one, what happened? 4 times! Unfortunately, LETWING couldn't help me because the warranty on the batteries had expired.
