Product Overview
The JK Battery Smart Shunt is a display-free 500A battery meter for installers and owners who want every reading on their phone. The 500A shunt measures bidirectional current and calculates amp-hour throughput, while a sense wire feeds real-time voltage — and all of it appears in the Bluetooth smartphone app: voltage, remaining capacity, current, power in watts, SOC, cycle count and estimated time remaining.
With no screen to mount, installation is compact and clean, and the unit works across lithium, lithium-ion, lead-acid and NiMH chemistries — a practical monitoring upgrade for golf cars, marine banks, RVs, solar storage and backup systems.
Core Features
- 500A Shunt Metering: A high-current shunt measures charge and discharge current bidirectionally and computes amp-hour throughput.
- App-Only Display: Every metric lives in the Bluetooth app — no panel cutout or display wiring required.
- Full Battery Picture: Voltage, remaining capacity, current, power (W), SOC, cycle count and time remaining in one screen.
- Real-Time Voltage Sensing: A field-installed sense wire delivers accurate live voltage readings from the battery.
- Multi-Chemistry Support: Works with lithium, lithium-ion, lead-acid and NiMH batteries for mixed-fleet use.
- Compact Install Kit: Ships with current shunt, shunt holder and sense wire for a tidy, space-saving setup.
Application Scenarios
Ideal for golf cars and utility vehicles, floor cleaning machines, aerial work platforms, marine vessels, RVs, solar installations and backup power systems where a phone-based readout is more practical than a fixed display.
Frequently Asked Questions
How does the JK Battery Smart Shunt 500A measure battery capacity?
The JK Battery Smart Shunt 500A uses a precision shunt resistor with coulomb counting — it continuously measures current flowing in and out of the battery and calculates an accurate state of charge, far more reliable than voltage-only gauges.
Can I check the readings on my phone?
Yes. The JK Battery Smart Shunt 500A has built-in Bluetooth and pairs with the smartphone app for live voltage, current, power, temperature and remaining capacity — useful when the battery is installed somewhere hard to reach.
Which shunt rating do I need?
Choose a shunt rated above your system’s maximum continuous current: 75A / 150A / 500A options cover most RV, marine and off-grid setups (larger ratings available on request). Running a shunt near its limit hurts accuracy, so leave headroom.
