Battery Cell

LiPo cells for UAV battery packs

A lithium-polymer cell is the basic building block of every UAV battery pack we supply. Each cell has a nominal voltage of 3.7 V, charges to 4.2 V (about 4.35 V for high-voltage cells) and should be stored near 3.8 V for long service life. Cells are connected in series to raise voltage and in parallel to raise capacity, which is why a finished pack is described as, for example, 6S1P or 14S1P.

How the S and P numbers translate to a pack

A 6S pack delivers 22.2 V nominal, a 12S pack 44.4 V and a 14S pack 51.8 V, with every series cell adding 3.7 V. Adding parallel cells multiplies capacity without changing voltage, so a 14S1P and a 14S2P share the same voltage while the second pack stores twice the energy. Discharge rating, written as a C-rate, describes how much continuous current a cell can deliver safely.

Choosing cells for agricultural and industrial drones

Spraying drones and industrial platforms need high energy density, stable voltage under load and predictable cycle life. Cell quality affects all three: matched internal resistance keeps the pack balanced, while a robust separator and electrode design reduces the risk of swelling after hard flights. Store packs at 3.8 V per cell, avoid leaving them fully charged for long periods and check balance before every mission.

Cells, finished packs and support

If you would rather buy a finished pack than build one, start from the Tattu G-Tech 16000mAh 6S1P for medium airframes, or the Tattu 22000mAh 12S and Tattu 22000mAh 14S packs for heavy agricultural platforms. For a pack sized to your own airframe, see our custom power systems.
