I had one of these on my V-Strom. Liked it well enough that I bought one for my Burgman, just haven't installed it yet. Note that it is very bright at night, almost distracting at times. If you have cataracts it might give you too much glare at night.I don't know if it is the best or not but this is what I have on my '12.
When the engine is not running the volt meter will tell you how many volts are in the battery, there are some very expensive meters that are supposed to show condition, and expected life left in them, but I have not had any experience with them.OP is asking about "battery monitor". Wouldn't voltmeters ONLY monitor the stator or the alternator output? I would think the battery monitor would monitor the condition of the battery.
Your $150 meter does the same as mine with duplicate indication of temperature and my ice light. It measures the voltage at the battery connected just like mine so will show charging voltage when the engine is running.OP is asking about "battery monitor". Wouldn't voltmeters ONLY monitor the stator or the alternator output? I would think the battery monitor would monitor the condition of the battery.
For example, I was on my way home from work one day. The bike (not Burgman) was running great. It was charging nice 14.1 Volts. Stopped at a gas station. Then bike had no battery power. It wouldn't start. The battery was at the end of its life. So if I had the battery monitor, I would have changed the battery before I got stranded.
I was thinking of getting something like this.
But I don't know if that would even be able to predict the battery life.
