Hi. So i have a 55 watt solar
array with a pathetically CHEEZY charge controller(thank you costco).
My charge controller has 3 led lights
. The first light
tells you you have 75% + battery
The second light
tells you ,you have between 25-75% charge.
The third light
tells you you have 25% or less charge.
So after charging my battery
to 100%, i run my fantastic fan for about 10 minutes on medium and my charge controller tells me my battery
is now at 75% and lower. Hmmm. Brand new battery from wallyworld rv deep cycle 120 amp/hr rating.
I decided to let my fridge(12v fridge) run my battery down to the third led light which is the 25% and less battery charge indicator.
I hook up my fancy digital battery charger which tells you the charge on the battery. The battery charger reads 70% charge.
Hmmm. My cheezy charge controller reads below 25% and my fancy battery charger reads 70%.
