Lipo Charging Instructions
- 1). Determine what voltage to charge your batteries at. A one-cell LiPo battery (sometimes designated as 1s, meaning a series of one) can be charged to a maximum of 4.2 v. If you are charging a battery pack, look at the markings on the pack to determine how many battery cells are in the series. For example, if the pack says 4s, this is a series circuit of four batteries and can be charged to a maximum 16.8 v. If there are two numbers, such as 4s3p, this means that the battery pack has four batteries on a series circuit and three on a parallel circuit. Only add up the series circuit batteries. A pack that says 4s3p still has a total fully charged voltage of 16.8 v.
- 2). Check the settings on your battery charger. If the charger has no settings, but it is the charger that came with the battery pack when you purchased it, charge as normal. If the battery charger is set to automatically detect maximum charge voltage, you will want to check the number displayed against your own calculations, and change the set maximum voltage if there is an error on the part of the charger. If the charger allows you to manually set the maximum voltage, set this to the voltage from your calculations in Step 1.
- 3). Plug the batteries into the charger exactly as instructed in the instructions that came with the battery charger. Check to ensure that the positive leads coming from the batteries are plugged into the positive ports on the charger, likewise with the negative leads. Crossing of the leads can lead to fires and destroy the batteries.
- 4). Place the batteries and charger on a concrete or otherwise inflammable surface.
- 5). Plug the charger in, turn it on and begin charging. LiPo batteries take only about an hour to charge, so do not leave the room until they are done charging. Wait until the charger indicates that they are fully charged, turn off the charger, unplug it and unplug the batteries.
