Should be 3 shunts which means the controller is expecting a 1.33 mOhm shunt. Typically 3 shunts ends up around 1.2x mOhms. Try 1.25mOhms and then start calibrating from there based off of how many amp hours you drain from your fully charged pack vs how many you put back in. Then calculate the error percentage and multiply the shunt value times that. I.E. you pulled 10Ah from your pack and put back 9.5Ah. 10/9.5 = 1.05263% difference. If your shunt is 1.25mOhm multiply it by 1.00105263 and you find out your shunt value is now around 1.316mOhm. Do this 2-3 times and you should have a shunt value that is fairly accurate.alsmith wrote:Does anyone have the shunt resistance value- it's for the cycle analyst RShunt setting. It doesn't seem to be the same as the 18 x 4110 FET controller.

I've written how to do this process before if you search through my posts.
