Tracker Battery + Adapter

$12.00

A 400 mAhr Lithium Polymer battery plus a connector adapter that works with the Featherweight GPS Tracker. The connector adapter can be installed horizontally as shown in the photo, or vertically. The tracker battery also plugs into the ground station enclosure for recharging in the field. The 400 mAhr capacity provides about 4-6 hours of tracker operation.
