My Celestron mount draws about 0.5A tracking. One of these lasts 2 nights. I have the unprotected flat top for a DIY power box.
I use a 2S pack with these in my heated vest. They power it for 4 hours on medium. Lightweight and safe with the protection circuit.
Charged these 6 months ago and they still hold 4.1V. Put them in my headlamp and ran for 2 hours on high. Excellent for emergency storage.
The protected button top is nearly 70mm. My Zebralight SC600 doesn't close fully. Works in my larger lights though. Great cell otherwise.
I built a external battery pack for my Canon using dummy battery and 2 of these in parallel. 6800mAh shoots all day. No issues.
