I had a charge controller that was burning $2,000 worth of lithium batteries in the system so after I got a new battery and this cheap charge controller it worked great, couldn't believe it as it was almost the cheapest controller on the web and charged in very low light. Basically, it is the quality of your panels that will charge your batteries. I used monocrystalline Renogy panels.
