Wow , getting set up for power gets complicated...
I got an ARB fridge (50qt) and a deal a 200Ah Renogy GEL battery with Ctek D250SA charge controller. I have a 100 W solar panel in bound (Rockpals)
Renogy 200Ah GEL battery
The issue came then that the Renogy GEL battery wants a charge voltage of 14.2 per the manufacturer. The Ctek charger controller has some awesome features (manages alternator or solar inputs, isolates crank and aux battery, 20A charging feed, selectable wet cell/AGM, etc.). However, it lists its output voltages as 14.4V or 14.7 volts depending on if wet cell or AGM batteries are used (again, selectable).
So, what will happen if I charge the Renology GEL battery on the closest setting it allows, the 14.4 V? I emailed both Ctek and Renogy and got somewhat incomplete answers. Renogy says "yes you can, but be advised that you may reduce the life of the battery". But by how much?
I don't want to kill this beast of a battery, but I also don't want to have to buy a different charge controller. What would the long term effects of charging it on 14.4V instead of 14.2V?
Any input would be appreciated.
