    Shunt settings

    Bought a renogy shunt and when you first set it up you fully charge the battery and set the shunt at 100% Now this would be ok for a lithium battery that could be run to 0% but not for an AGM battery Was thinking it might be better to set the 100A Battery at a full capacity of 50A so once it got...
