I have a victron lifepo4 90ah battery connected to my smart bms 12/100 and a smart victron shunt. I am using the bms to charge the house battery from the vehicle alternator. The vehicle has a temperature controlled alternator (new hilux) I have fitted 2 x 30amp fuses and set the bms to charge 40amps. This is a new set up and the most charge I can see from the shunt is 12amps when the engine is cold, and drops down to 5amps when hot. The house battery is at 40%. Why can I not get any more charge ? My friend has same car and enerdrive dcdc and he can get 40amps. I have triple checked wiring and all is good.
thanks Luke
