This charger I have is set a little too high. I want to reduce its final cutoff voltage. There are 3 trim pots. Anyone know which is which or have a schematic??? Cheers
Usually 1 is amps 2 is volts and 3 do not touch.
Mostly rojitor is correct, anyway look for kingpan charger This link has good info: https://www.avdweb.nl/solar-bike/electronics/portable-lightweight-lifepo4-ebike-battery-charger-800g
Thx, yep 2 altered the open circuit voltage. I’m interested, how did you know? And lastly, I’m assuming 3 has something to do with the cc dropping as it approaches cv??
Wow!!! Thx, how did ever find that??? Clever guy.
just probe the dc output and see what happens when you try one of the pots. If the voltage doesnt move, its probably the wrong pot
Thx, the answers above are correct. VR2
