CC/CV Charging of Lithium Batteries with a Magnum Inverter

If I can do this it would be excellent.

Thank you so much for your help.

Do you have the manual for the remote? You may want to first get the version of software in the remote under the Tech button. This will allow you to look up what features it supports. You can download the manual for the remote that has all the settings from the Magnum website if you do need it.

I don’t use the CC/CV setting either. The Custom has a lot of settings available and provides a pretty good degree of flexibility. However, some of the Magnum values are off a bit due to wire loss and the lack of remote battery voltage sensing. A Magnum BMK will help with this. I installed the Victron SmartShunt, which provides good accuracy but won’t control the Magnum. I keep notes on my setup and will alter it as needed to meet our needs for traveling. It’s definitely a learning process compared to the original lead acid batteries. However, my battery compartment is so much cleaner now with no acid. The weight savings was incredible as well.

Yeah, I have no regrets of far. The Epoch 460 has been awesome.

I think I have an older revision of the Magnum Remote or Inverter, that doesn't have those more complex settings in the Custom mode. I'm going to just move between CC/CV and Custom as needed. It's not ideal, but it's better than spending >$2k for a little software change.

I have the BMK and the shunt, but the Epochs are all new to me (less than one week). So it's a learning curve.

Thank you both for your help, this has been very insightful.
