No, these aren’t some sort of weird, blue AA battery, this is actually a 18650 Lithium Ion Cell.
This is an incredibly simple one cell 18650 Battery Holder. When someone thinks of 18650 Cells they tend to think of flashlights first, which is fair since that is what they have been primarily used for.
These are very slim, extremely light weight batteries based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production. Each cells outputs a nominal 3.7V at 2000mAh!
This high discharge LiPo is a great way to power any R/C, robotic, or portable project.
This charger accurately balances and charges Lithium Polymer, LiFe (A123), NiCd and NiMH batteries.
