I don't understand, why three wires? No matter how I connected it to the battery, it shows zero. I connected the red one to the plus, the black one to the minus - zero! Yellow to the plus, black to the minus - zero. Red to the plus, yellow to the minus, zero blinks. In short, some kind of crap.....
A good control device for measuring voltage. I install such ones in battery packs (of course with a switch). I recommend Joom and the seller!
Received the goods on time. The voltmeters are working, just need to calibrate them more accurately. Thank you
Good device for mounting in a charger. I recommend the product, the seller, and Joom.
