There’s a guy on YouTube that does a lot of testing on lithium batteries. He tore apart a Weize battery about the time you bought yours and he was very impressed with it. He considered it the best “cheap cheap Chinese “ lithium battery at that time.
I bought one of the Weize batteries about two months ago and shortly after I bought it he done a follow up video about that battery.
He bought another one and tore it down and the cells and BMS circuit were different from the original one. Same case different guts.
I most likely have the newer one so time will tell if it’s a good one. You should check him out before you buy another one. Theyre not the same battery.
