another source for agm batteries
Hi, It's time for me to consider replacing four of my batteries that are now 8 years old. I came across this on Amazon. Any one have an opinion on this company? http://www.vmaxchargetank.com/...

A temp comp charger actually simplifies this by adjusting charge stages according to a reference 77F. The charging profile is then based on 77F and you ignore battery temps because that is handled already.
The Tristar models of solar controllers are known for their ability to accept custom parameters that meet whatever your battery manual requires. They can sense both battery volts and temperatures.
Converter/chargers are dumb by comparison.
I think all MPPT controllers over say, $200, have adjustable setpoints and remote temp and volt sensing. Some also have adjustable rate of temp compensation, i.e. how big voltage increment per every degree above/below 77F. I only wish they could generate current at all times :)...
