AGM charging

[Dirt Rider]

When I bought my AGM batteries I assumed I could charge them like I did my wet cell batteries, but now my understanding is they need 14.5 volts instead of the 13.5 my alternator kicks out. Also my shore power only does 13.5 for my house battery. Any ideas on how to get my truck and FWC charger to go to 14.5?

Have you got the battery charging specs?

With those in hand, you might want to invest in a DCDC charger that has configurable charging, like the Victron Orion series.

For the shore power, I assume you have an iOTA charger? Hopefully it is of the generation that has the ability to plug in a “dongle” to change the charging profile. If not, you will need a different ac/dc charger too.
