Product Overview
The BM16 is the wide-range member of the smart battery monitor family, offering shunt options all the way up to 750A for the largest battery banks. A separate LCD display unit shows voltage, current, state of charge and total amp-hours, while the Bluetooth app mirrors extended metrics — remaining capacity, power in watts, cycle count and estimated time remaining.
Like the rest of the family it supports lithium, lithium-ion, lead-acid and NiMH chemistries, making it a single monitoring solution for golf cars, marine vessels, RVs, solar storage and backup power installations of any size.
Core Features
- Up to 750A Shunt Range: The widest shunt selection in the family — 75A, 150A, 500A or 750A — scales from small carts to large banks.
- Dedicated LCD Display: A separate display unit keeps voltage, current, SOC and total amp-hours visible at all times.
- Bluetooth App Mirroring: The smartphone app adds remaining capacity, power (W), cycle count and time remaining.
- Multi-Chemistry Support: Compatible with lithium, lithium-ion, lead-acid and NiMH batteries.
- Complete Install Kit: Ships with current shunt, shielded wire, display and 22AWG sense wire.
Application Scenarios
Suited to golf cars and utility vehicles, floor cleaning machines, aerial work platforms, marine vessels, RVs, solar installations and backup power — especially larger banks where the 750A shunt option earns its keep.
Frequently Asked Questions
How does the BM16 measure battery capacity?
The BM16 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 BM16 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.
Do you offer wholesale pricing on the BM16?
