Renogy batteries and charging

[Groover]

I am thinking about putting Renogy lithium-iron batteries in by RV but Renogy sales tells me that I need a charger made specifically for that type of battery. I currently have a Magnum ME2012 charger/inverter that has lots of adjustments but nothing that specifically says lithium. I tried every way that I can think of to contact Magnum about an upgrade with no success. So I am asking here. Does anyone here use a Magnum charger with lithium-iron batteries and how is it working out for you?

Ask Renogy for the specific requirements for charging their batteries.

But 2oldman won’t that void the battery warranty?

I couldn't find any direct answers to that on here, and your charger won't say Lithium, for sure.

After finding out the bulk charge voltage required, set the Mag to that. Set absorb time to zero. Set float to whatever voltage required. Magnum should allow that.
