I was able to push big red to 36 amps input and about 9 amps output, but it plateaued there with about 12.2v reaching it.
Was briefly touching 400 watts charging but this tapered pretty quickly and it went from trning 30 watts of power into heat, to nearly 65 watts as it got hotter and hotter
it is rated for 40 amps max.
There is a 3rd potentiometer for ;low voltage protection; on the input, and I need to play with this more, as it was limiting output until I twiddled it, but I kept spinning it hoping to get more than 36 amps input and it said Nope.
Charging at 360 to 400 watts, around 9 amps (1C for 10s2p of BAK45D) ) depending on Esk8 battery voltage, is acceptable. I'd like to have big red in a casing with a bult in meter and finger twist potentiometers and better ventilation, but that's another project that sounds great but will likely never happen.
CC/CV Booster charging from 12v nominal is the limiting factor, but 150 to 250 watts is hardly trickle charging.
Being so 12v nominal centric is a hard habit to break.
