Geometrics MagArrow, User Manual

Page: 6 / 39

Geometrics recommends 1800 mAh lithium polymer batteries from Zippy or Turnigy. These have been
verified by Geometrics to be non-magnetic, and therefore, the best option for MagArrow surveys. These
batteries should be available from various online vendors including the Hobby King website:

https://hobbyking.com/en_us/turnigy-nano-tech-1800mah-3s-65-130c-lipo-pack.html
A single 1800 mAH battery will run the MagArrow for about 2 hours. It is recommended to have at least
two spare batteries so that one may be charging while the other is in use.
Also, this battery charger and discharger is recommended:
https://hobbyking.com/en_us/accuell-s60-ac-charger-us-plug.html
This is a balanced charger that charges one lithium battery pack at a time. Each of the three battery cells
within the battery pack are charged independently. It has a discharge mode to automatically lower the
battery charge state to 30%. IMPORTANT: It is required by law to reduce the battery charge state of
these lithium polymer batteries to 30% before shipment.
Installing the Battery
On the underside of the MagArrow, there is a door to the battery compartment where the batteries will
be stored.
1. Remove the battery compartment cover with the provided JIS#1 screwdriver. It is very
important to only use the provided JIS#1 screwdriver to tighten or loosen the battery door
screws. Do not use a Phillips Screwdriver.
