Nicest controller for the size and price.

I used it to charge a lithium battery, and it's amazing and better than my previous older solar charge controller. however, you can set it for a lead acid battery also.

This one actually works as advertised

I’ve gone through several solar charge controllers that have failed to meet expectations. I’m running a 12V electric fence charger with a lead-acid (small tractor) battery. After tried many solar charger controller then I switch to this charge controller. I’ve had it in service for 2 weeks now with the same solar panel and battery as before and it has kept the battery perfectly charged. very happy with this product.

Allows More Charge Power Than Previous Unit

Had issues with the previous charge controller. This unit was recommended by my RV Builder. Works providing more charge power than the unit it replaces. Recommended.
