Key Features & Benefits

Precise Current Sensing: Attaches to a standard 50mV / 500A shunt to provide highly accurate battery current readings to your MidNite charge controller.

Enables EndAmps Functionality: Allows the Classic or KID to end Absorb charging based on battery current falling below a programmable threshold, preventing overcharging or undercharging.

State of Charge Monitoring: Provides real-time SOC%, remaining amp-hours, net amp-hours, and battery temperature data on the controller's display.

Temperature Compensated Capacity: Automatically adjusts battery capacity based on temperature for more accurate SOC readings in varying climates.

Compatible with Classic and KID: Works with MidNite Solar Classic and KID series charge controllers (Classic Lite requires Local App or MNGP for setup).

Low-Side Shunt Measurement: Designed for safe low-side measurement on the battery-negative side of the shunt.

LED Status Indicator: Built-in LED provides visual confirmation of proper operation.

Type 1 Environmental Rating: Suitable for indoor installation.

5-Year Warranty: Backed by a 5-year warranty.

Made in the USA: Designed and manufactured in Arlington, Washington.

not tight around your legs
Nice socks. They are thin and light weight so they are ideal to wear with snug fitting shoes. They have a nice cable style design to dress them up. I have been wearing a pair all day, and they do not dig into my legs at all. Love that. I have not washed them, but I see no reason why they would not wash up well in cold water and a low dry temperature. The price is great so give them a try.

Nice ruffle socks
First of all, I like the thickness of these ruffle socks. They are not too heavy nor too thin, making them ideal for all seasons wearing. The ruffle edges make the socks unique and beautiful. The quality feels quite good. I like the socks in six different color, all of them are beautiful.

Cute, very breathable material
These socks are super cute and comfy. I love the material-- it's light and very breathable. The ruffles are so cute. I think these socks work great with ankle-high boots or chunky sneakers.
