Renogy Rover 40 amp mppt overcharging

[Dr. Know 13]

I have to 100 watt monocrystalline panels look up to a renogy Rover 40 amp mppt and I'm having a problem with it overcharging. I have to AGM batteries that I think the controller burnt out charging them at 16 volts. I tried setting it as sealed, flooded, user and nothing seem to slow it down until it burnt up my batteries.
I would think there would be some way to keep it from overcharging the battery's until there fried.

You have two not to, correct? Replace the defective Rover or get a new one under warranty

I have a Renogy Rover 40 amp Li Negative Ground Unit that works good. It is in USR mode settings for Lifepo4. I suggest you contact them and get a replacement.
