Review on High-performance OOYCYOO MPPT Charge Controller 30A Solar Panel Regulator for Lead-Acid, Gel, AGM, Lithium Batteries – LCD Display, Max 100V Input by Lyric Gibbs

This controller regulator display battery charger promised to be the perfect solution for my automotive needs. However, after I put it to the test, it failed to deliver. The charging process was slow and barely increased the battery life. The only positive aspect was the compact and portable size. Overall, I would not recommend this product as it's not worth the price for the minimal charging efficiency it provides.
