So I have the eco-worthy 20a DC to DC charger with MPPT (not using solar charging) I have connected to my 100ah eco-worthy LiON battery as shown in the user manual and set the charger to LiON mode. The charger input is measuring 14.47 volts when engine is running which is what I would expect,cthe charger output to the leisure battery is measuring 0.3 volts across the blue+ and black - the power and charging lights are blinking red and the LiON is solid blue. Looking at my battery in the app it's status is flicking between standby and charging when im guessing it should just stay at charging when the engine is running, the battery SOC is 31% is it possible I have a faulty charger in that it's output is so low?
