I'm just about done with my conversion to lithium batteries (2 100amp Battle Born batteries) and am trying to figure out how appropriately configure the settings on the Magnum ME-RC connected to a MS2000 inverter charger.
On the Battle Born website they have a video that says to set battery type to custom, absorption voltage to 14.4v and the float voltage to anything less than 13.6. (It's at https://battlebornbatteries.com/can-...-battery-bank/)
In the text on the same page as the video, they also say to choose the custom battery type and set the bulk charge voltage to 14.4V, the float to 13.6v or greater (which contradicts the video!) and the low voltage cutoff to 11.5v.
Then in the comments to the page someone asks about the battery type to CC/CV and Battle Born says both automatic and CC/CV will get the "desired" effect. They say if using CC/CV then:
1. Max amps will be the maximum you want the charger to supply(refer to the .5c charge rate), for your 200 AH bank it will be 100 amps.
2. Charged Volts should be 14.4 v.
3. End Charge, set this to 20 minutes per battery(40 minutes for your bank).
4. Recharge, you can set this to 13.4 volts and this will be when the bank reaches 90% SOC. If you would like the Recharge set lower you could go with 70% SOC with the voltage at 13.2v. With these settings you will not need to address the Float or equalize as they are disabled.
I am wondering which way I should go with my setup in regard to the automatic or CC/CV choice. Are there are a lot of other settings when using the CC/CV choice that I don't think are available with the automatic choice? I've seen discussion of these settings elsewhere in this forum but no one seems to talk about the automatic choice.
Can anyone point out the pros and cons of each choice? (Note that I have an older, from 2017, ME-RC Rev. 2.8 so don't have the direct Lithium battery type choice.)
