Description: 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.

Customer Comments

  • 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: http://www.all-battery.com/pcbfor74vli-ion186501850072vbatterypacks75alimit-32004.aspx) 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 https://www.sparkfun.com/products/10473? 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?

  • 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?

  • How can I connect it to a breadboard? Thanks!

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

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

  • So any suggestions about how to go about charging these?

    • 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 :)

  • What is the self-discharge rate on these puppies?

  • Not a good deal at all. a 2200mAh 50C can be had here, from one of the best RC suppliers around . http://www.hobbyking.com/hobbyking/store/11910Turnigy_nano_tech_2200mah_2S_25_50C_Lipo_Pack.html

    Then for a buck more you can double the capacity to 5000mAh http://www.hobbyking.com/hobbyking/store/9437ZIPPY_Flightmax_5000mAh_2S1P_20C_hardcase_pack.html

    • Except Hobbyking is a crap company that steals designs from SFE without any recognition. As shown here…

      Now where have I seen a pcb like that before???

    • Do my eyes deceive me, did the price on this just drop from $17 and change to $13.95

    • When it comes to batteries like this, “you get what you pay for” is often true. It’s interesting that this battery is significantly larger and heavier than the “equivalent” Turnigy battery. But if you really want the cheapest price for a rating, try lingering on a hobbyking product page for a while and in a few minutes a pop-up with a discounted price may appear.

    • Looks like markdown ate your links, try the correct formatting (see ‘formatting help’ link below comment area).

      • Links are as follows.

        first second

        not entirely apples to apples comparison. first battery is less money, but only 50C burst, 20C continuous. if you get a 30C continuous, it’s about the same price. for the second one, it’s only 20C constant, 30C burst. So, it’s higher capacity, but less discharge rate. TL:DR - yes, batteries with lower discharge rates can be had much cheaper.

      • These appear to be the corrected links: 2200mAh 5000mAh

    • The links don’t work and I’m not finding a 50C for cheaper.

      • just go to hobbyking, and click on Batteries & Accessories, then click the 2S selection. the links above are for a 2200mAh 50C for $11.84 and the 5000mAh for $18.19
