Polymer Lithium Ion Battery - 1000mAh 7.4v (Sale)
This high discharge LiPo is a great way to power any R/C, robotic, or portable project. This is an excellent choice for anything that requires a small battery with a lot of punch. The voltage is low enough not to tax your regulating circuits, and the discharge rate is high enough to accommodate a lot of electronics and a few small motors.
The battery has two cells and outputs 7.4V storing 1000mAh of charge. Because this is a dual cell battery pack, a special charger is needed. This battery is not compatible with single cell chargers. A compatible charger is listed below.
Note: Care should be taken not to short circuit or overtax these batteries because they don't have any built-in protection circuit.
**Weight: **85g (2.99oz)

Polymer Lithium Ion Battery - 1000mAh 7.4v (Sale) Product Help and Resources
Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Hey all! Hope you're doing good!
I had a bad experience with the 1st battery I bought. It swelled (inflated).
Looking at the MSDS document, found this "...and it is desirable that they be stored in a low-temperature environment"
Should I keep this battery on the fridge while not in use for a short period of time (charged or discharged)? (1 week)
In case it needed to be stored in the fridge discharged, how do I discharge it?
Regards
Anybody had issues with the wiring on these batteries? The connection to either the battery or discharge plug seems to have problems on mine - wiggling the wire can disrupt power.
I'm trying to create my own protection circuit. How low can these batteries safely be drained?
Just saying that these batteries are not Lithium Ion but Lithium Polymer.
I ordered this recently and it does not come with the connector pictured. It comes with a T-connector and JST-XH charge plug. It does NOT come with the JST-RCY discharge plug as described.
Pinout for charger or datasheet at least?
Same as for any battery pack. You've got 2 connectors coming out of this. For your balancer/charger, you would use the 3-wire connector. Between Black (negative/minus/anode) and Yellow is one cell, and between Yellow and Red (positive/plus/cathode) is the other one. You don't really need to know about this, though.. the charger should have a 3-pole female connector socket that you would push it into (only fits one way). The other connector is for discharging, between the black and the red are both cells in series.
Got my batteries (2 of these) and charger today (sku: PRT-10473) and started reading the manual for the charger. It wants to know:
1. Amperage of the charge
2. Charge volts
I set it to .1 amp and 7.65v, connected the batteries charge and discharge plug (per manual for balance charging) and it seems to be charging (5 min without and explosion :)
What are the correct amp & volts to charge these critters? Since it's a dual cell I feel confident about the 7.4v, not so much about the amps.
Is the height actually 13mm? 1.3mm doesn't seem plausible.
fixed. yeah, 1.3mm would be nice :-)
25C * 1000mAh = 25A max discharge rate! Though not for very long, 1Ah/25A = 0.04 hours or 2.4 minutes. These are still great for quadcopters, etc. that need a whole lot of power for a little bit of time.
