Dick H., regarding the battery-mounted state-of-charge display

After using their batteries over the last eight months, they have proven to be a perfect choice for our dry camping needs and we are extremely pleased with them.  We use them in conjunction with our RV's solar panels to provide for all our needs.

Their after-sale customer service is excellent as well."

It was great! Batteries worked all night with no issues. Gone is the fear of boondocking. We watched TV and ran the microwave and the residential fridge. Glad we bought them.
