Battery Monitor issue

A place where users can meetup with other FlexPower One users and can find support for one another. A great place for people who have not purchased the FlexPower One yet to look up information.

Gotcha, but the take away is that your 49.6V is not nearly charged full...but at least now you know how to get it fine tuned for a better 100% display.

I never dived deep into custom settings staying with defaults. Indeed, absorb to float stage trigger is time based, not current. I set battery type, voltages, and capacity and go. Charging efficiency is set to default Auto.

I never felt that I needed to use custom set-up, SOC is very consistent in similar charging conditions day by day.

I did have a problem a few years back with a code displayed (don’t remember the number). With Magnum service folk’s assistance, I was able to bring the system back to life. It was inconclusive what was the problem, could be overheating. It works flawlessly since. I hope I answered your questions, if not I can dig more but I am far away.
