Altus Metrum 850mAh LiPo Battery - Main image
$6 $10 In stock

These are very slim, extremely light weight batteries based on Polymer Lithium Ion chemistry.  Each cell outputs a nominal 3.7V at 850mAh.  Comes terminated with a standard 2-pin JST connector - 2mm spacing between pins, that plugs directly into the battery connector on Altus Metrum flight computers.

These batteries are approximately 0.25x1.2x2.0" (6x30x48mm), and weigh about 19g (0.67oz).

Note that while we sell these as 850mAh cells, our supplier varies their process from time to time, and batteries may be stamped 850mAh or 900mAh.

NOTE: CANNOT BE SHIPPED OUTSIDE THE USA. CANNOT BE SHIPPED VIA 2ND DAY AIR OR NEXT DAY AIR

WARNING:  Unlike most LiPo batteries made for hobby use, these batteries are made specifically for use with Altus Metrum flight computers, and do not contain an over-current protection circuit board!

Hannah ★★★★★

Fits perfectly in my compact rocket airframe thanks to the ultra-slim polymer cell, and the JST connector made wiring it into my altimeter a breeze. The 850mAh capacity gives me plenty of burn time for dual-deployment flights.

Olivia X. ★★★★★

Was pleasantly surprised by how slim this battery is — it slid into a tight bay without any forcing. The JST connector made hooking it up quick and easy, and it's held a charge well after several uses.

George ★★★★★

Perfectly fit the battery compartment on my high-power rocket altimeter, and the JST connector made swapping it in a breeze. Gave me plenty of power for a full dual-deployment flight with juice to spare.
