KH-F Series Battery Monitor Voltage & Current Meter 100A–600A
KH-F Series Battery Monitor & Manager — Precision Voltage & Current Metering for EVs, RVs & Solar Systems
Take full command of your battery system with the Elubor KH-F Series Battery Monitor (KH110F / KH140F / KH160F). Engineered for electric vehicles, RVs, solar setups, and off-grid power systems, this smart battery manager delivers real-time voltage, current, power, amp-hour, and watt-hour readings — all on a single compact display. Bluetooth connectivity lets you monitor your battery status wirelessly from up to 10 metres away.
Made in Mainland China.
Why Choose the KH-F Series?
- Three current range options: KH110F (0–100 A), KH140F (0–400 A), KH160F (0–600 A) — choose the model that fits your system.
- Wide voltage measurement: 0–120 V (external power supply) or 10–120 V (self-powered).
- High resolution readings: 0.01 V voltage resolution, 0.01 A current resolution, 0.01 W power resolution.
- Comprehensive monitoring: Amp-hours (0–9999.99 Ah), watt-hours, power (0–72 kW), battery capacity (0–100%), and elapsed time (up to 999 hours).
- Built-in temperature monitoring: External sensor range −20 °C to +120 °C.
- Smart protection system: Configurable overvoltage, undervoltage, overpower, discharge/charge overcurrent, and over-temperature protection with adjustable recovery and delay timers (0–99 s).
- Bluetooth connectivity: Wireless communication up to 10 metres; 99 addressable communication channels (P01–P99) for multi-device setups.
- Low self-consumption: Measuring board ~0.4 W; display header ~0.5 W.
- 1-second sampling rate for responsive, up-to-date readings.
- Shunt-based (splitter) sampling method for accurate non-invasive current measurement.

Frequently Asked Questions
Q: What is the difference between the KH110F, KH140F, and KH160F battery monitors?
A: The three models differ only in their maximum current measurement range: the KH110F handles 0–100 A, the KH140F covers 0–400 A, and the KH160F supports 0–600 A. All other specifications — voltage range, resolution, Bluetooth, protection features, and display — are identical across the KH-F series.
Q: Does the KH-F series battery monitor include a relay?
A: No, a relay is not included with the unit. Users who want to activate automatic protection switching (overvoltage cut-off, overcurrent disconnect, etc.) will need to source and configure a compatible external relay separately.
Q: Can I use the KH-F battery monitor with a solar or off-grid system?
A: Yes. The KH-F series supports voltage up to 120 V DC and current up to 600 A (KH160F), making it well-suited for solar battery banks, off-grid storage systems, RVs, and electric vehicles. The wide amp-hour tracking range (up to 9999.99 Ah) is particularly useful for large-capacity battery installations.
Q: How does Bluetooth monitoring work on the KH-F series?
A: The device features built-in Bluetooth with a maximum wireless communication range of 10 metres. It supports up to 99 addressable communication channels (P01–P99), allowing you to monitor multiple units in a larger system via a compatible app or display.
Q: What protection features are built into the KH-F battery manager?
A: The KH-F series includes configurable overvoltage protection (0–120 V), undervoltage protection (0–120 V), overpower protection (up to 99,999.99 W), discharge and charge overcurrent protection, and external over-temperature protection (−20 °C to +120 °C). Protection recovery time, delay time, and standby entry time are all user-adjustable.
