IF YOU HAVE A CAMPER THIS IS SOMETHING YOU NEED Review: works well so far. - Works well as advertised. Have to be close to car for information. Useful for seeing battery charge as car is prone for some reason to drain the battery. My only suggestion is the black and red wires be a couple of inches longer - it did fit but make it more fiddly. ## Features - 🔋【Automotive Car Battery Monitor】 ANCEL BM300 battery tester is designed for all 12V 100-2000CCA batteries.
