Review on 🔌 Cllena DC 40V-90V to 24V Converter Voltage Regulator Reducer: 48V, 60V, 72V Step Down, 24V 10A 240W Converter - Waterproof Buck Transformer Power Supply for Golf Cart Club Car LED Light by Marty Wainwright

I recently built my own battery using Li-ion batteries. When fully charged, the battery is 16V. Although I should have used LifePo4 batteries to get a reliable 12V battery, I decided to try one of those instead. Worked great for what I needed to do. Maintained a good 12v when the batteries went down from 16v to the 11v I installed. It didn't get very hot either, despite only drawing 12A from it. Although it's a little larger than I expected, it did its job well.
