Lithium Ion Battery - 2200mAh 7.4v

Added to your shopping cart

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 2200mAh 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: This battery is not available to ship to Alaska or Hawaii, or through any express services (2-day, overnight), or internationally. This is temporary! Check out our blog post for more information. Additionally orders may take longer to process and therefore do not qualify for same-day shipping. Sorry for any inconvenience this may cause!

Note: Care should be taken not to short circuit or overtax these batteries because they don't have any built-in protection circuit.

Note: This item is non-returnable. If this item arrives damaged or is not functioning properly, please do not hesitate to contact us to see if further actions may be taken.

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.

2 Electrical Prototyping

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.

    Hello Sparkfun techies! I am hoping you can tell me the max voltage these cells should be charged to. I'm guessing it's either 4.1 or 4.2 but it does not list the necessary cutoff voltage in the datasheet. Thank you

  • Can i use this battery in a vizo xl ... im tired of recharging the original battery for over an hour after 10 minutes of flight. i know it wont fit, but will it power the drone enough to fly it

    IT IS A TECHNICAL QUESTIONS THIS KIND OF BATTERRIES: Hi!,we have bought 100 Lithium Ion Batteries, I'm not saying from this website, actually we bought them from a re seller that was supposed to buy from sparkfun , However is not the same battery above

    Well, it is my case, The batteries was bought several months ago(8 months approximately), and until now we kept them in boxes, and when we opened the box , we've noticed the almost all of the batteries were swollen!, My we have done something wrong? o it is about the batteries quality?

    Hi! Question: if this battery requires a protection circuit board (PCB) how would you hook it up? The battery has 3 wires for charging and 2 wires for the load. All the PCB's I've found (like this one: are designed for individual cells, not battery packs like this one. Since you only have 2 wires and don't have access to the individual cells to hook up to the PCB. (2 wires does not equal 3 connections needed).

    Would you be able to charge somewhere between 4 and 8 of these with one of these I want to redo my laptop into a pelican case with custom cooling systems and a custom battery pack for it. I plan on using these as a system for the charging circuit and using the batteries as going directly to the dc port on it?

    Can you charge these with the Sunny Buddy?

  • Stephen Marquard / about 10 years ago * / 1

    Is there any way to charge these batteries from a solar panel, for example would it be safe to charge the two cells individually with separate chargers like this design: multi cell LiPo charging ?

    can I use this to power rover 5 motor controller? how long does it last if you leave it on constantly?

    Hello, good morning. Can i power an Arduino Pro Mini 328 - 5V/16MHz or Pro Micro - 5V/16MHz with this battery

  • Member #442918 / about 11 years ago / 1

    I don't have a T-plug connector, can i just connect my output to the white header?

  • Blacklab1 / about 11 years ago / 1

    So any suggestions about how to go about charging these?

    • Kamiquasi / about 11 years ago / 1

      You'll want a balancing charger. Check the Related Products below for one, or hit the corners of the interwebs where RC enthusiasts may be found - these battery packs are most commonly used there :)
