Polymer Lithium Ion Batteries - 6Ah

sku: PRT-08484

Description: If you need some juice, this 6Ahr triple pack is for you. 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 solid 3 cell pack (6Ahr) comes terminated with a standard 2-pin JST connector - 2mm spacing between pins. Do not attempt to charge these with anything but a charger specifically designed for Lithium Ion batteries.

These three cells have been match for internal impedance and can be fully charged and discharged in parallel.

Features:

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

Dimensions: 0.75x2.1x2.1" (19x54x54mm)

Weight: 110g (3.88oz)

I wonder if this can be used in the port-o-rotary, without problems to the charger / charging circuit?

Please can this be charged with only one LiPoly Charger - Single Cell 3.7-7V: https://www.sparkfun.com/commerce/product_info.php?products_id=726 A quick answer would be appreciated. Many thanks!

Non-official response: My guess would be technically yes, although it would take quite a very long while (given that max output on that charger is 280 mA, and that it won't maintain that max throughout the 6Ah charge...

use the LiPoly Fast Charger http://www.sparkfun.com/commerce/product_info.php?products_id=8293 it has a max output of 1A and under basic math it will take about 6 hours to charge a completely died battery

That charger description says "charges single cell lithium polymer batteries" but isn't this a 3 cell? I'm also interested in using that charger with this battery.

While, yes, the charger is for single cell, that will not be a problem in this case. This battery has all three of its cells hooked up in parallel, so the charger will see it as a single cell. When batteries are hooked up in series is when you start looking for a charger that can handle two or more cells.

I am charging this with the LiPoly Charger - Single Cell 3.7-7V Input charger also sold here and using it to charge a iphone 3g via a MintyBoost Kit - v2.0. After fully charging the battery via a 5V 1A wall wart (~29 hours, due to the chargers 280mA limit) I only get approximately 2 full recharges before the battery is completely drained. Is it possible that the individual cells aren't properly connected?

no it's not hooked up wrong you have to remember the inefficiencies of a boost converter (approx 40% to 70%) And the iphone internel battery is 1280 mAh battery you are getting about 42%

1) If the connector is only rated to 2A and this pack can do 2C discharge (or more optimally 0.2 - 1 C), and the wires also cannot handle the capacity, can the wire/connector setup easily be changed where they connect to the pack? 2) Just a heads up that the datasheet above is the one for the 2Ah pack, not this 6Ah one...
