Was looking for a replacement/upgrade for these headlamps Was looking for a replacement/upgrade for these headlamps
Size: 112945
Review Image by Chaos
This battery dimension fits the headlamps I ordered where the battery just wasn't holding a charge as long. I am hoping with almost 50% more battery capacity, I won't have to do this for quite a while. I went ahead and installed the connector (already in there soldering) for when that time comes.

Useful battery, but double-check the polarity!
Size: 112945
As noted in the product title, beware of the polarity. For some reason, there are two common wiring conventions. Since I've been using a lot of Adafruit boards lately, I needed it wired for "center negative." I tested it right after it arrived and quickly reversed the polarity. No soldering needed — just a male and female JST cable and some solderless connectors like Wagos. Moral of the story: always check polarity before plugging in a LiPo! Once rewired, it charged and worked perfectly with my dev boards. ... show more

Fits perfectly in Featherweight Tracker ground station - BUT SWITCH THE POLARITY!
Size: 112945
I searched high and low for a higher capacity 1s LiPO that would fit the little battery compartment in this tracker ground station. This one fits perfectly. The connector has pos and minus switched (It's for UAVs which have the opposite polarity). It's easy to change it, do not push down on the metal locking tabs, pry up on the plastic locking tabs, pull the wires out, switch them, push them back in. Perfect. ... show more
