  • Great battery pack, has plenty of power!
Size: 3.7V-JST-PH2.0 MM
Hooked it up to my charger circuit, and it charged nicely, it's been running my device for quite some time now, looks like the capacity on the label is pretty close to what it is, rather than like other companies that exaggerate. Comes with a JST connector that does just that, connects it to your device. I'm very happy with this pack, and I'm picky about my batteries. Do be careful, their listing has 2 identical looking batteries in it, a 3.7v and a 7.2v you need to pick the one that's right for your device. If you don't know, consult your local nerd. ... show more
