Easy installation, visible yellow, green or red led indicator on the plug terminal for battery health and while the bike is in idle mode it will show active charging of the battery. Good rubber seal to minimize dust and water into plug terminal. Good insurance during cold weather and long-term storage.

A great way to check the health of my lithium battery ...
A great way to check the health of my lithium battery in my enduro bike - I leave this hooked up and can see it blink every 30 seconds or so. Not something I would plan on checking constantly - but useful at the end of a ride to see if I needed to charge up or not. I did some hard riding with heated grips, GPS, and aux lighting - and wanted to make sure I was not running the battery down. I keep the battery on the optimate when in the garage - so I don't know how long this would take to draw down the battery.

Disappointed
Conected to my battery and seems to work with charger at first. FYI: It is a parasitic drain on your battery because the light stays on all the time. As well, the terminal ends are not copper Could of been $5 less + free shiping. After nearly 6 months, this plug has a defect. Had it connected to Antigravity ATX-HD-RS purchased on Amazon. Unfortunately the plug some how got hot and fried the wires. Sad thing is I cannot seem to get a warrant replacement from seller.
