I have a lithium battery in the bed of my truck to power off off-road lights on my rooftop tent and an extra 12 V accessory plug and this little monitor lets me know how much battery power I have left and how much I’m using

The monitors works. It provides the percentage of remaining battery and the current voltage. I needed a monitor for my camper.The instructions do not make much sense. I am thankful for the other reviews that pointed out the small button next to the incoming wires. It took a while to get it set correctly.Be patient and work thru the setup and you will low cost battery monitor.

Added this to my son's e-dirt bike. It was easy to install and does exactly what I needed.

The ad clearly shows two devices. Only if you carefully read the entire listing, does it say you get one only. This is extremely deceptive. Change the damn picture! Instructions on how to set this up are a joke. If you don't know how to set it up, it won't work right. So what's the point of even purchasing this product? What the hell does "set the number of the battery string" mean? When I hook this up it said I had 100% charge when the battery is nearly dead. POC.

I used this product to measure my battery as it is charged by a solar panel. Seems very accurate.

Since almost everything is made in China these days, it should come as no surprise that the instructions are written in extremely poor English. There are english words on the page arranged into sentences that make no logical sense. If you play around with it long enough, ignoring the written directions, you can program it to sort of work. I couldn't get setting S-1 (rotating V and %) to work. S-2 and S-3 work as described. I can't tell what S-5 is for so I'll stay away.

I use for batteries on trickle charge. I just like to eyeball every now and then. Beats breaking out vm every time.

LO CONECTE EN PARALELO AL LA CORRIENTE DEL ENCENDEDOR QUE AHORA ES UTILIZADO PARA LOS CARGADORES, LO PUEDES DEJAR ENCENDIDO SIN QUE ESTÉ CONSUMA LA BATERÃA, VALE LA PELA

Der DC Batteriekapazitätsspannungsmesser ist genau das, was ich gesucht habe. Die Anzeige ist hell und gut ablesbar, das grüne Licht sorgt für klare Sichtbarkeit auch bei schlechten Lichtverhältnissen. Ich verwende ihn sowohl für Blei-Säure- als auch Lithium-Ionen-Batterien, und er funktioniert einwandfrei.Besonders praktisch ist der integrierte Alarm, der mich bei niedriger Spannung sofort warnt. Die Installation war einfach, und der Batterietester tut zuverlässig seinen Dienst. Eine klare Empfehlung für jeden, der seine Batterie im Auge behalten möchte!

L’installazione è semplicissima e non necessita di alcuna configurazione. Io ad esempio monto una batteria al litio ed è bastato collegare i poli (io l’ho collegato con innesto al caricabatterie usb).La sorpresa positiva è che non serve accenderlo e spegnerlo manualmente ma lo fa in automatico con l’accensione e lo spegnimento della moto.Lo uso da pochi giorni ma per adesso sono molto soddisfatto.Forse l’unica cosa è che non c’è la variante arancione come il mio quadro, quindi ho preso il bianco che un po’ stona.

This is a very easy installation. Just needed to put ring connectors on and connect to leisure battery. Worked immediately. Then mounted into side of van for easy viewing. It can be switched on and off to save the battery as its powered off the battery it's connected to.Cheap and cheerful.
