Mandobart, it's good to see that you tend towards John Fetter as the internet source for go9d battery info as well. Here's the page on ultra fast charging.


http://batteryuniversity.com/learn/a..._fast_chargers

According to this 1C is considered a fast charge and not ultrafast. I've had mostly good results using my 25amp charger and have never had an AGM seem warm to the touch after charging, including my 6ah 12v. I will ask John to specifically recommend charge amp and volt regimen and limits for various AGM batts and see what he says.

It should be noted though that in the comments sections of many of the pages Mr Getter is severely critical of modern AGM batteries and says that we'll all be lucky if they last a year at reasonable capacity.
