Review on ⚓️ Reliable Protection for Marine, RV, Camper, and Trailer Batteries: NOCO HM327BKS Group 27 Snap-Top Battery Box in Black by Brandon Peters

I used to buy an ingenious battery box with a USB connection, additional 12V sockets and an LED battery test system. The LED system worked on the stand after the battery was charged, but when installed and used after 10 days there were no readings. It was too complicated to be reliable. It's just a regular ventilated box. Does what it's supposed to do and I have other ways to monitor battery health. I like it MUCH better.
