BFKK

BFKK DC 8-100V 200A Battery Monitor 2.4 inch LCD electrical system tool

SKU CH-AF29-HRW08

Monitors DC voltage from 8 to 100 V and current up to 200 A on a 2.4 inch colour LCD with backlight alarm

  • Tracks 8-100V DC systems up to 200A
  • 4 inch colour LCD stays readable in bright sunlight
  • Backlight flashes when capacity drops below 20%
  • Measures voltage ±1% and current ±0.5% at 20 samples per second
  • Configurable alerts for voltage, current and screen timeout

Battery Monitor for 8–100 V Systems

The BFKK DC 8-100 V 200 A monitor tracks voltage, current, power and capacity on 12 V, 24 V, 36 V, 48 V and 60 V installations. It suits RV owners, boat operators and solar installers who need a single instrument for charge and discharge analysis across multiple battery banks.

Configurable Alerts and Display Options

The unit adds a backlight alarm that flashes when remaining capacity drops below twenty percent or voltage falls under a user-set threshold. Menus let you clear no-load current, set total capacity, adjust backlight brightness across eleven levels, choose between two colour themes, select English or Chinese, and define auto-off timers based on time or current level.

Compact Two-Board Design with Shunt

A 2.4 inch colour LCD board measuring 86 by 53 by 17 mm pairs with a separate measuring board of 56 by 36 by 34 mm that houses the shunt. The split layout lets you mount the display at eye level while keeping the high-current path short, and the 20 readings-per-second update keeps the values current during rapid load changes.

Questions about this item

Does the shunt need periodic recalibration or replacement during normal use?

The monitor measures current through an external shunt rated up to 200 A; the shunt is a passive component with no calibration schedule mentioned, so it typically lasts the life of the installation unless physically damaged.

What measurement limit is reached first when the system runs continuously at high load?

The current range tops out at 200 A and the power calculation at 50 kW; whichever of those thresholds the load hits first becomes the practical limit for sustained monitoring.

How much heat or noise does the unit produce when it stays powered all day?

The display board draws only backlight power with no fan or moving parts, so it generates negligible heat and runs completely silent during continuous operation.
