What are everyone's thoughts on a Powermax Boondocker 75amp converter/charger for my 3 group 31 AGM's? I have a Honda 2000 that should power it fine.
If you haven't already got the 31s, check the discount clubs for 6V AGMs for $169 that might fit.
The last time I checked, Boondocker only does 13.6V after bulk. Most converter/chargers are like that. It would be ok if you are only interested in bulk charge followed by a good solar charger that holds 14+V in the Absorption stage.
Inverter/chargers seem to have smarter charging, but can be pricey if you do not also need an inverter.
Take a look at the Xantrex Trucharge2 as it has a nice charging profile, also pricey.
Some portable chargers, with an AGM setting, are ok for AGMs.
