I have a 100 watt panel, a 75/15 mppt and now a 75ah optima yellow top.
It powers a Small 18l compressor fridge and charges a few usb devices.
The previous battery, a beaut amg was used 6 weeks and lived only 2 years, and i would like the optima to last a bit longer.
What are the best settings for the mppt? i can adjust them with the dongle
