29.6V / 24.500mAh / 70A / 725Wh / 2800g

Lion Power battery packs are manufactured using Panasonic Sanyo NCR18650GA  Lition-ion cells, with a 3.6 - 3.7V voltage, 3500mAh capacity and 10A continue discharge per cell. Cells are combined in series and parallel to get the required voltage, capacity and maximum current.

This Panasonic Sanyo NCR18650GA cells are the same ones used in the manufactured of batteries for Tesla cars, that are Pioneers and number one in the market of electric vehicles.

Lion Power is the first manufacturer to distribute in Europe Litio-ion batteries specially adapted for use in Drones and Aero-modeling.

Panasonic NCR18650GA cell has the specific energy of more than 250 Wh/kg, what give around 70%-100% additional to conventional Lipo batteries. That means that Lion Power batteries have until double energy capacity for a same weight that conventional Lipo batteries.

Sanyo Energy a few years ago became a wholly owned subsidiary of Panasonic, who is also the supplier of batteries to power Tesla’s electric vehicles.

Advantages Li-on batteries:

- More autonomy and less weight

- Between 70-100% more energy density than conventional Lipo batteries.

- Lifespan higher than Lipo. They hold many more charging and discharging cycles than Lipo batteries.

- Less maintenance, do not swell or spoil if stored at half load

- Can be charger using conventional Lipo chargers.

Disadvantages:

- Delivery of maximum power more limited so it is necessary to size the package properly for our power requirements.
