Thunder Tiger says that this charger is capable of 1000 watt of charging power but that's with a 27V 40 amp power supply charging 8S. When charging the max 14S that the charger can do, it drops down to 588 watts. Plus it can only balance charge, there's no way that the charger can bulk charge without balancing and I needed that option.
It's a disapointing charger for the price and I lost big selling it but it was just collecting dust.
