from progressive site.. Maximum charge power: 1400W at >23.5V (1000W max. per channel)
That's at 6S though. Far as I can tell toe is a driver and that means he's probably running 2S or 4S. Even charging 4S at 40A you'll only consume ~672W per channel.
You really start to 'need' 24V once you start working with higher voltage batteries.
