[icecream]

Like new. Upgraded to new system and no longer have need for this monitor. Includes the shunt. If not picked up in Marin County, California, then you will pay actual shipping cost too. If you buy new will cost you $300-350. Asking $200.

Here is a summary of it:

"Knowing the State-of-Charge of your battery is like knowing the amount of fuel in your gas tank. To avoid getting stranded with a dead battery, accurate battery bank monitoring is essential.

Rather than relying upon voltage to determine battery state-of-charge, this monitor calculates battery capacity by measuring amperage in and out of one battery bank with the included 500A shunt. As well as informing of the percent of charge, it also calculates hours remaining, Amp hours (Ah) remaining, and total charging cycles.

With the built-in MOSFET External Circuit Relay, you can also use it to control external circuits based on any value measured by the M2. Bright OLED display is auto-dimming and easy to read with high resolution and sharper contrast compared to traditional LED displays. Programmable 92dB alarm. Waterproof to IP66 standard.
