So it showed up on time and appeared to be pretty legit... first power cycle ran for about10-15 min till batt died.... hooked to charger 4 separate times w/ out showing charged... hooked to a bigger multi battery balance charger and the battery caught fire and nearly burned my garage down... luckily I was watching it.... needless to say this isn’t my first lithium battery nor will it be the last, but it was a first actually seeing a battery swell and catch fire
