i bought this 600w charger from bmsbattery some time ago. adjusted to charge my 12s lipo battery it worked w/o any problems.
for the new bike i need it set to 24s life or 86.4v and want to monitor the charging process. unfortunately the wattmeter works up to 60v only, and there is not cheap replacement for that. so i ordered a 50a amp meter and and volt meter. there are some displays that can do both, but you have to press a button to switch between V and A, and i want to monitor both at the same time.
so this is the amp meter:

and this is the volt meter:

the amp meter has blue digits and the volt meter red ones. both will fit into the charger's case. i could have put both of them in a seperate case, but it like it clean.
this is the charger:
charger opened - only top side:
this is the amp meter w/ shunt:
logic board, and 12V and GND pads:
amp meter connected to power:
negative charging cable cut to insert shunt:
i sanded the shunt to ensure a good soldering pad, and used a propane torch to heat it up so i could solder the cables to it:
shunt connected:
done. and working
this is the wattmeter for comparison. values are a bit off, but i can't say which one is the correct one before measuring with my hq voltmeter.
the voltmeter will be installed next week and then 2 holes will be cut into the case to install both of them.
enjoy if there are any comments please let me know
