You will also have to up the fuse/circuit breaker rating that is installed close to the batteries between the batteries and converter/charger. If you have a 45AMP rating remaining here it will blow the fuse or trip the breaker when the battery demand gets higher than 45AMPS...
My inline fuse protection was 30AMPs original with my small converter/charger and it is 80AMPS with my PD9260C setup. Probably a tad too high but that is what I found in the goody box here... My original #8 cable was upgraded to 4AWG to use with the PD9260C unit...
ADDED Note: When camping off the power grid I usually pull aroound 20AMPS DC to run things and when I am using my PD9260C running off of a generator to charge up my 255AH battery bank I see around 52-53 DC AMPS being demanded by my battery for 15 minutes or so when first starting up my BOOST charge mode.
