Hi,
I bought a cheap chinese cell tester and need to add a load resister to the meter.
As usual it doesn't come with any documentation.
My question is: what resistor or load should i use ?

Which one is it?

Asuming you can define the resistor to whatever you want:

The resistor will depend on what current you want to test at. 1A is common so for doing 1A you need
3.7V/1A=3.7Ohm

So you would need one that do 5W atleast and around 3.7Ohm.

It says it can do 0-10A so a 1A load with a 3.7ohm resistor will work
