    Amazing Batt!!

    Very easy to mount, very easy to install.

    Using the bluetooth app, i can read the battery temp, charge/discharge amps and the no. of cycles the battery has done. Can also see the health of the battery, and each individual cells. I can see also the ability to add additional batteries and link together, however at this stage i only have the one. I may look into adding a second down the track
