Remember to first check/calibrate charger display, use mutlimeter to measure the booster output and adjust charger meter to show same voltage, current might need also calibration. Booster output power: 12V * 5A = 60W / 42V = 1.4A, i tweak my charger for 1.2A max. 24V * 5A = 120W / 42V = 2.8A, i would use max 2.5-2.4A ish. Of course you build this charger at your own risk, i am not responsible for any damage. Orginal design: https://www.thingiverse.com/thing:4545724
