Terrific little monitor

Reginald RALPH on Oct 8th 2021

Hooked up in 30 min to my minn-kota case . Now I can see in real time how much power I’m using and how long I can stay out on the lake trolling . I’m also using the 20amp charger it take only two hours to fully recharge the battery after 9 hours of trolling for trout using a 45 lb minnkota riptide . https://youtu.be/5J0WciBtoJc

I installed 3 of them on 3 battery banks in my RV. They work just find and I rely on them to manage solar and shore charging time.

500A Battery Monitor

Donald Laverdure on Jan 24th 2021

Great Monitor, Shows both the state and a graphic battery image for level and it shows Watts, Volts and remaining time calculated. I found the time remaining was very accurate, the green back-light is not overpowering and it pulses when charging, it is a nice looking display that will go well with the interior of my motor-home. 500Amps is plenty for even a 3000 watt inverter.
