How to Make a LiPo Battery Pack
LiPo battery packs are the latest in new technology as they produce twice the energy and are half the weight of any other rechargeable battery. They can be used in a wide variety of packaging shapes. The highly efficient qualities of the LiPo battery pack make it the best choice for the operation of many small devices, especially in the operation of remote control aircraft.
Things You'll Need:
- Li Po batteries
- Wire strippers
- Pen
- Electrical insulating tape
- Knife
- AWG gauge 16 wire
- Determine the voltage needed for the electrical device. Each Li Po cell has a nominal voltage of 3.7 volts. Use this figure to compute the amount of batteries needed for your LiPo battery pack. Batteries must be wired in series to combine the voltage from each battery.
- Lay out the correct number of batteries. The positive terminal on the top has a small metal knob. The negative terminal on the bottom is flat. Alternate battery terminals. For instance, using three batteries, there should be two positives and one negative terminal at one end and two negative and one positive on the other end.
- Number each battery with a pen. Put electrical insulating tape around the batteries, making a pack. Cut two pieces of 16-gauge wire with a knife. These go between the Li Po battery pack and the device. Calculate the amount of short wire pieces you need. Cut wire pieces and strip plastic from each end down to the wire.
- Label the long strips of wire, one for positive and one for negative. Using electrical tape, connect positive wire to the positive terminal of battery one. Connect negative wire to the negative terminal of the last numbered battery in the pack. Connect the end of a short piece of wire to the negative terminal of battery one. Connect the opposite end to the positive terminal of battery two. Continue the process by connecting negative to positive in sequence. Connect the last end of the short wire left to the positive terminal of last battery.
- Close up the LiPo battery pack by wrapping it in electrical tape. Leave the two long wires ready to be connected to the device.
