Versatile Battery Monitor

The JAMHER 2-piece battery capacity voltmeter monitor suits lead acid, lithium, ternary lithium, lithium iron phosphate, polymer lithium ion and memory batteries across 3-15 series configurations. Each unit operates from DC 8-70V and shows capacity or tension on a waterproof PVC-protected LCD. Two devices, two connection wires and four quick connection terminals arrive in the pack.

Buckle Mount and Sleep Mode

Installation uses a buckle system with 58.5 x 28.5 mm fastening holes, so no screws are required. Press the function key to cycle between capacity percentage, voltage or alternating display, while the setting button selects battery type P, L or F and cell count. The backlight toggles on demand and the screen sleeps after 10 seconds of inactivity to save power.

Replaces Basic Voltage Gauges

This meter upgrades simple analogue gauges by adding automatic percentage calculation, selectable chemistry profiles and a sleep function for portable packs. The jump is worth it when you need readable state-of-charge data on wheels, UPS units, EPS systems or mobile power supplies without wiring a dedicated display controller.

Questions about this item

What DC voltage range does the JAMHER voltmeter monitor support?

The monitor operates on a DC supply from 8 V up to 70 V, covering most lead-acid and lithium packs used in vehicles and portable power units.

What are the exact panel cut-out dimensions for the buckle mounting?

The fastening holes measure 58.5 mm wide by 28.5 mm deep, so the panel cut-out must match those dimensions for the built-in buckles to engage.

How do I configure the meter for a 12 V lead-acid battery with multiple cells?

Power the module while holding the setting button until the current parameter appears, press the setting button to select P for 12 V lead-acid, then use the function key to set the number of battery rows.
