Batteries are magic storage devices of electrical energy. To have and idea how well your battery is functioning requires monitoring. If you want to know the condition and health of your battery this meter is the solution.
With this smart battery monitor you have no more questions about whether or not your battery condition is ok or not ok. This meter is smart because it tells you all at ones four things for the price of one. This monitor tells you your battery:

  • Capacity (Wh).
  • Load (W).
  • Voltage (V).
  • Current (A).

Battery Shunt.

The meter works with a heavy-duty shunt resistor that can handle 100Amps. To monitor the battery voltage and current aswel as for battery charge and discharge a toggle switch is added for switching between battery charging and discharging.

What you get.

The whole package exits out of everything needed to install the monitor. The package exists out of the following components:

  • The battery monitor.
  • A User and installation manual including a schematic .
  • One 100Amp shunt
  • One six pole toggle switch

No extra materials are needed to install this monitor other than a screwdriver and some 18..22AWG gauge wire. Everything is packed in a strong carton box.
