What is a Battery Monitor?
A battery monitor, often referred to as a battery meter or a gauge, is a fuel gauge for your RV, boat or off-grid cabin’s battery bank. It provides real-time information about the energy or charge remaining in your battery bank at any given time, along with the voltage and current information.
How Does a Battery Monitor Work?
A battery monitor continuously tracks the energy flowing into and out of your RV’s battery bank, calculating remaining charge. It functions like an accounting program for your house batteries, providing crucial information and preventing energy overdrafts. This essential device helps you monitor power flow, avoid shutdowns, extend battery life, and optimize your energy system, ensuring you’re always aware of your RV’s power balance.
Why Use a Battery Monitor?
Battery monitors are invaluable for maintaining your battery bank’s health. At a glance, a battery monitor can inform you if you have sufficient reserves to power devices like your TV, cooktop, or CPAP machine overnight. They also help you detect if your batteries are losing their capacity to store charge as they age, alerting you when it’s time to replace them. You can easily perform monthly capacity tests to track changes over time.
Do I Need a Battery Monitor for My Motorhome or off-grid cabin?
Absolutely! A battery monitor is especially crucial if you spend a lot of time off the grid or boondocking. A motorhome without a battery monitor is like a car without a dashboard fuel gauge. It helps you manage your energy usage and ensures you always know the status of your battery bank.

●Shunt based Battery Monitor. More accurate, stable & reliable than Hall effect based monitors.
●Measures battery % full, based on amp hour measurements for accurate information on state of charge (SOC). This method is more accurate than meters
●Use the TM-2030 Battery Monitor with the WF-2030 WiFi module for remote access from smartphones, tablets and PCs. WIFi offers better range than Bluetooth.
●Allows Amp-hrs based battery charging when used with the SC-2030 Solar charger to prevent or minimize sulfation. This feature is exclusive to our products and has been demonstrated to extend battery life.
● Displays battery charging or discharging Amps (or Watts). Useful for conducting energy audits of your system and help you determine if you need to add storage (or charging) capacity.
● Tracks # of days since the last time batteries were charged or equalized.
● Suitable for 12, 24 & 48V battery banks.
● Audible low battery alarm, based on volts and % full. May be silenced. Avoid inverter shutdowns by properly charging the batteries.
● Shows replaced percentage of charge, compared to most recent discharge. To extend battery life, charge batteries 5-20% more than what was taken out during the last discharge event.
● Incorporates lightning protection.
● Easy to read display. If needed, display may be turned off.
● Logs battery bank data that is useful for troubleshooting your system.
● Provides streaming battery bank data on its serial data port.
Data for each of the last five charge/discharge cycles:
● Length of the cycle.
● How long ago the cycle ended.
● Lowest % full reading
● Lowest battery voltage.
● Cycle charge efficiency (percent)
Data for each of the last five days.
● Highest voltage that day.
● Lowest charging current.
● Total percentage overcharge for that day.
● Sizes: smaller (RV) is 3 x 5-1/4 x 1-3/8 inches deep. Larger (A) is 4-1/2 x 4 -3/4 x 1-1/4 inches deep.
● Requires a shunt: Either a 500A/50mV shunt that allows current measurements from 0.1-400 Amps. Or, a 100A/100mV shunt that allows current measurements from 0.01- 75 Amps. L
