I ended up purchasing the Hitec X2 AC Plus Black Edition back in 2018. Since then it has puffed two batteries and given me an "Over Charge Capacity Limit" error. Both of the batteries are less than 3 years old. They are 2S 6000mAh LiPos. I charge them at 6.0A and 7.4V and always ensure they are balance charging. I am concerned there is an issue with this charger and it is unsafe. It should not be overcharging since the settings are correct. I've never had a LiPo battery puff during charging before this charger. Has anybody else had this issue?
I've reached out to Hitec.
