Polymer Lithium Ion Batteries - 860mAh

sku: PRT-00341

Description: 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 860mAh! Comes terminated with a standard 2-pin JST connector - 2mm spacing between pins. These batteries require special charging : Do not attempt to charge these with anything but a specialized LiPo charger.

Battery includes built-in protection against over voltage, over current, and minimum voltage.

Features:

2C continuous discharge
Excellent long-term self-discharge rates (<8% per month)
Robust power source under extreme conditions (-25 to 60C)

Dimensions: 0.23x1.16x2.0" (5.84x29.5x51mm)

Weight: 18.5g (0.65oz)

The description says "Battery includes built-in protection against over voltage, over current, and minimum voltage." Is this all the protection that is needed? Is the low-voltage protection meant to be a last resort, or can I rely on it to safely cut off the load, so that I can then recharge the battery? Thanks

It's great that is has a protection against over voltage. But how long it will be whenever i use my laptop... Is it cheaper than the old ones....?

Great battery, mine was actually 900mah.

What is the output voltage? Description says "Each cell outputs 3.7 Volts". Is it a 2 or 3 cell battery? Thx!

Single cell lipo - http://en.wikipedia.org/wiki/Lithium-ion_polymer_battery - nominal/design voltage of 3.7v, ~4.2v fully charged.

The only problem I had was using those JST Right Angle Connector. When you completely plug the battery in those JST connector, it is very hard to get them unplug! So hard that I pull off the wire out of the battery connectors and made them useless since I rip off the small metal notch! They are literally glued together once snap in. I had to use a small screw driver to get them unplug.

is it possible to charge this through the lilypad LiPower supply board?

I had the same problem as robomaniac; the JST connector 'glued' itself into the LiPo USB Charger JST connectors. Still havent managed to get them apart, but i damaged the battery wires trying :-( I'll have to get some JST connectors elsewhere in order to make this usable. (also, my battery says 900mAh as well)
