Description: This LiPo is a hardy little battery pack. They managed to pack a constant discharge rate of 25C into this battery. For its size, it has one of the highest discharge rates on the market. This is an excellent choice for projects that don't use a lot of energy but need a lot of current for short amounts of time and need to be small.

The battery has two cells and outputs 7.4V storing 500mAh 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: Due to shipping restrictions, only two batteries can be shipped together at one time. We should be able to ship more than two batteries at a time by the end of 2014.

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


  • 7.4V 2-cell pack

  • High power output to size ratio
  • JST-XH charge plug
  • JST-RCY discharge plug

Dimensions: 55x31x13mm

Weight: 39g (1.4oz)

  • how can i charge them i need small charger can i use them at same time while charging

  • can I charge this battery with two PRT-10217 LiPo Charger Basic - Micro-USB ?

    • No. Those boards are designed to charge single cell lipos. This requires a special charger capable of multi-cell batteries. Check the related products below for the proper charger.

  • Will these fit inside the Arduino project enclosure? Looks like it might be tight…

  • Is this battery really secure ? There’s 2 cells serialized. But when several Lithium cells are serialized, they can become unbalanced. Example, for a total of 6V, 1st cell voltage can be 4,5V and 2nd cell voltage 1,5V. So to serialized several cells, a Battery Management System (BMS), which control each cell separately, is mandatory. Is there a tiny BMS inside this little pack?

    • There is no battery-management system inside the pack. However, the cells are factory-matched to have as identical characteristics as possible, which eliminates most of the problems you describe when charging or discharging. Additionally, when you use a smart multi-cell charger such as the one in the related products, the charger will take control of the individual cells to re-balance them during the charging process.

  • What is the maximun charging current?

  • is the weight really 39g, so light?

    • yeah, I think so. I checked it against our internal shipping weight and it checks out. seems legit.

  • When will this be restocked????
    I need three of them for my Engineering Project ASAP
