agm battery charge issue
what would cause a AGM battery to reduce its charging amperage, without the voltage reaching the set voltage cutoff in a CC mode stage of a charger example, battery is at 13.6 yet a pd9245 in boost...

As stated the wire is to small and/or to long for optimal charging. AND this can include the negative wire.
The 48A from the charger first goes to the loads which is 48-14A=34A and 14A into the battery from your numbers.
You can also check for the PD recommended wire size per the distance and compare that to your wire size. And as stated the connectors etc could also be part of the problem.
there are no loads. if voltage drop was the issue, wouldn't it would increase as the amperage goes up? thus somewhat limiting it?
it seems odd to me it can do full amperage at a lower charge. but then the voltage loss causes it not to correctly charge at like 90% full. IDK seems off to me. maybe i need to run some calculators.
at 5 amps the voltage is 14.4, the wiring has been replaced.
