The Details...............

Its annoying when your battery goes flat without warning. Some vehicles, such as older motorcycles, dont even warn you if your alternator has failed. You run on battery until the lights get dim, engine misfires and everything stops. Worse - Some bike alternators can suffer regulator failure, and your battery and ££££ electrics get fried with excess voltage.

With this neat little device, you get a nice clear warning that something is wrong, so you can get home fast before your battery dies, or stop right away before your engine ECU and other costly electronics are damaged.

PLUS when your bike is in the garage in storage, you have a quick and easy way to monitor the battery state - LED blinks green, yellow or red to let you know if you need to top your battery up.

The large 10mm green/red/yellow LED comes with a black mounting bezel, with just two wires you connect into your electrical system. One to battery positive, one to negative. We couldn't have made it simpler.

The table below show the operating range of the unit, used with LITHIUM type batteries:




Note from the ranges shown that LITHIUM batteries have a higher voltage output than standard 12v lead-acid cells. Lithium battery suppliers may call them "12v batteries", but they are much closer to 13.5-14v in normal operation, this is why you need this special matched-to-Lithium model.


On the road you should only see constant green (no distracting flashing in normal operation) - flashing red green means alternator failure (overcharging!) and dropping to yellow means your system is heavily loaded (heated gloves, etc).

 When parked or stored, you see flashing green, yellow or red for battery 'idle' status.


Please note: this unit is for bikes fitted with LITHIUM batteries, made by Shorai or similar. If you have a standard lead-acid type battery, please purchase a lead-acid type from our shop. This unit WILL NOT work correctly for any battery other than LITHIUM types!!!!!!!
