  • Working well in my electronics projects
Size: 1
This battery pack has worked flawlessly in my setup so far. It has been a practical power option for a small electronics project, and the connector was convenient for my use. I am giving four stars rather than five because I have not had enough long-term cycle testing to judge battery life over time. I plan to keep testing it in future projects and will update this review if anything changes. ... show more

  • Not great for some (low current) always on devices
Size: 4
On the one hand the power density and form factor is great. I built some AAC communication devices and they ran for days on a single charge. The problem is that the cutoff voltage of 3.0 is lower than it should be for low draw devices. This is a problem for always on devices that rely on the battery to cut itself off before it start damaging the cell. Long story short went on vacation and the device went from 3 days run time to about 2 hours. For lithium polymer, the low voltage cutoff should be 3.3-3.5 under low load, depending on who you ask. ... show more
