An audible alarm warns if the battery level gets dangerously low. It will also show the starter battery voltage. For apple users a more sophisticated app, with additional features can be purchased from the Apple app store. Compatible with iPhone, iPad and iPod touch. Offers Apple Watch App for iPhone. (Requires iOS 9.0 or later).

The monitor, which draws a meagre 2 mA, is supplied with a 100 amp shunt and a premade cable assembly to simplify connection to your service battery.
