handy for campervan leisure battery
installed in about 5 minutes - bluetooth connected 1st time really easy and there it was the voltage of my leisure battery handy for when all the kids are using my battery to charge all there phones - it enables you to not damage the battery and run it too low - ok so it has a crank setting which i have no need for on a leisure battery but you can set it to notify you when battery gets low which for me after destroying two AGM batteries because we used to run them flat as i had no way of telling pre my solar kit is fantastic - good but of kit for not a lot of money. IF YOU HAVE A CAMPER THIS IS SOMETHING YOU NEED

Muy util y preciso
Muy útil. Tengo una autocaravana y se lo he colocado a la batería auxiliar para el habitáculo. Ofrece una gran cantidad de datos y fiables, por lo que da mucha tranquilidad, sobre todo los cortos días de invierno en los que anochece muy pronto y durante el día la carga de la batería deja mucho que desear. Saber en todo momento en la situación de la batería Yo lo he colocado en la parte superior de la batería con una cinta de pegar doble cara y listo..

Solide efficace et très bien adapté à l'usage
A positionner entre les bornes de la batterie: charger l'application, connecter le Bluetooth et le produit est très fonctionnel. Parfait pour surveiller rapidement l'état de la batterie du tracteur tondeuse par exemple.
