I am thinking to get rid of my NC106 from Outback, which are not doing well at all after 3.5 months, and the best alternative I have found so far is Deka Promaster DC 12 V 155 AH C20. Does anyone have an opinion on this?  Will these work for some heavy loads during the day (somewhat over panel capacity)?  I know that even 4 at this capacity will handle my needs at night, and will easily be charged by my panels even on a cloudy day

    IMHO, you would be better off going with a string of 6v golf cart (~225ah) or L16 (~350ah) flooded. The higher capacity would handle larger surge loads better, and all else held equal, will have lower depth of discharge and longer life.

    Second the golf cart batteries, especially flooded for their forgiveness, robustness and reliability. I'm assuming Nicaragua based on the latitude of 12° stated in your other thread, here is a link to a Trojan distributor.
