Battery Storage VoltageUpdated 3 months ago

Keeping your battery at maximum charge when not in use or leaving it almost drained are not good for your battery. To maximize the lifespan of your Li-Po battery, ensure that you stick to the storage voltage specification.

When it comes to LiPo batteries, there’s something called “storage voltage.” If you're not going to use your LiPo battery for a while, you won’t just casually put it in a drawer and expect the power capacity to remain the same.

The battery that ships with your SwiftPaws Kit is actually a battery pack with either three (3) or four (4) internal cells depending on which Kit you have.  A fully charged LiPo cell is 4.2 volts, while a dead cell is 3.3 volts.

If you plan on letting your battery sit for a few weeks, the storage charge should be 3.8V per cell:

  • For the 11.1v Home Original battery pack, which has three internal cells,  charge to 11.4v for storing it.
  • The 14.8v Home Plus battery pack, which has four internal cells, charge it to 15.2v for storing it.

Long Term Storage

When storing the battery for a long term (more than 3 months), it is recommended to place it in an environment with a temperature of 10-25°C, a low temperature without corrosive gas. 

During long-term storage, the battery should be charged and discharged once every 3 months to maintain battery activity and ensure that the voltage of each cell is within the range of 3.7 ~ 3.9V. (multiply the number of cells x 3.7 for total)
