Overview


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.

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.

Battery Watt Meter

Item was promptly delivered and is performing as advertised. No issues with installation or function.

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 these
