Ever wondered how much power was being drained from your battery? It's often difficult to measure this without special equipment or expert knowledge - until now.
Enter the Battery Watt Meter, a simple device that is easily installed and provides you with all the key ratings of your battery loads in real time.
Installation is easy - the watt meter has two ring terminals for connecting to your battery, and an anderson plug for loads. The device is installed in-line between your battery and loads. Once there is power flowing through, the device will initialise and show you a full range of ratings including:
- Current (Amps/A) at the present moment
- Voltage (Volts/V) at the present moment
- Power (Watts/W) at the present moment
- Total Amps (Amp hours/Ah) since device initialised
- Total Power (Watt hours/Wh) since device initialised
- Highest Voltage Maximum (Vm) since device initialised
- Highest Power Peak (Watt Peak/Wp) since device initialised
- Highest Current Peak (Amp Peak/Ap) since device initialised
The Battery Watt Meter only requires a tiny 7mA draw to operate, so there will be no significant reduction in your power production during usage.
150A Battery Watt Meter has a rating of 4.58/5 based on 26 reviews.

Watt Meter x 2?
All Seems OK. Good looking and appears well made Maybe you should offer an adapter cable set ( X 2 as a kit) to allow interconnection between test sources, I finished up purchasing 2 units because I wanted install one permanently into my battery box (hence the lug model) so I purchased the lug model. I then noticed the Allen plug unit on another W/site which would have solved my problem first up and is multi purpose. I now have a more universal unit after making adaptor cables with alligator clips and Allen plugs which surely would have been a cheaper result.Drew Wilson on 16 August 2019
Battery Watt Meter
Item was promptly delivered and is performing as advertised. No issues with installation or function.Carol K on 8 August 2019
Useful, but could be better
Provides everything you might want to know about a battery powered circuit, but missing a few features that would make it even better: 1. LCD display is only readable in a very narrow range of angles, surely they could use a better display. 2. There is no way to reset the accumulated values without shutting the circuit down (and everything plugged into it). Would be nice to have a reset switch. 3. Only measures current in one direction (discharge or charge) if you want to measure both you would need two of theseAlastair B on 29 June 2019
