AGM Battery Charging THE PRIME DIRECTIVE

I'm using the PT100 and it does integrate nicely with the Magnum inverter/ charger (hybrid) following the settings set throught the Me-Arc. This is with GBS LiFePo4 Batteries which have their own EMS CPU (shunt and more) so no BMK.

Off-topic, but I gotta ask:

GBS makes LiFeMnPO4 batteries, but I've never seen them advertise their own BMS (or EMS). Could you provide more detail about your BMS and/or where you got the system?

I suppose the basic idea is the same: like Mex says, you don't want to overcharge an AGM (or undercharge it). And you can use something like Magnum's BMK to be sure you don't. A Li battery's BMS provides the same function and cell balancing as well as other protections, depending upon the BMS.

Heck, for my 24V system I even have a Victron Battery Balancer that ensures the two 12V banks in series are charged properly (they are different brands and ages). A Li BMS should do the same but at the individual cell level.

I purchased and had it installed at Starlight Solar in Yuma. Yes same concept as Mex said about AGMs. Without going into the weeds on this thread I suppose the difference is what the end user sets their own charging parameters as long as the charging source that has adjustability in settings. If anything happens that would cause conditions beyond programmed limits, the BMS will disconnect the charge source or loads.

Here they explain their BMS.
