renogy dual input charger dc 30A won't stop charging after the battery is full

[cathallan]

Hello, Guys,

I got a new Renogy 30A dual inputs charger (alternator and solar) to charge two 100AH Lithium batteries. it charges fine, but keep charging when battery monitor says the battery is 100% full. also the charger's battery light won't turn to green(full charge) from yellow. I am worrying about fire hazard if it won't stop charging.

I used multimeter to measure battery voltage as 13.5V. solar panel charging voltage as 17V with good sun lights.

Renogy charger manual says battery light should turn to green color when it goes from bulk charge state to constant voltage charging state. what does constant voltage state mean? and what triggers it?

Renogy's customer service doesn't help at all, they don't know what they talk about.

any help will be highly appreciated! thank you.

Was anyone successful in getting Renogy DCC50s User profile to float for Li? SOLVED! DYNOMAN IS A LEGEND

I used the default Li profile on my Renogy dcc50s for a year...and my batteries (2 SOK's and a Battleborn) all had their capacities drop by far more than I expected. I replaced the SOK BMS's on warranty (they had old / wonky balancing logic) I decided I needed to finally use a user profile...
