How to build a $20 47A power supply

[Ola]

I do agree.. But i`m wont be pulling full amps for that long time with every charge..
I also have max 5s batteries, so the charger will charge at 850w maximum.. Thats approx 970w at 0.85, so theres still a good margin up to the 1150w maximum on the PSU`s.. And thats at stock 24v... Wouldnt it be producing less heat at 27v, being more efficent?

I`ll do some testing and measure temps to see how it works out..
I think i will be installing a switch for the fans as well.. for minimum + maximum settings, in case i want more cooling :)

At 20A charging, the air coming out of the psu`s are cold as the outside air hehe..
