Lipo Batteries and Safety

Lipo Batteries

Check out Greg Gimlicks article in Model Aviation (July 2015) on Lipo battery packs, very helpful

 

The Lipo Batteries that we fly with are great in terms of the power they have and how much they weigh. If the batteries are not handled correctly the result can be nasty fire

Be Gentle with the balance wires, the wire can break as shown below

My charger has a setting called “Storage”, this takes the battery down to the correct voltage when you are not using them

 

Be careful when it comes handling the Lipo batteries

Do not short the battery when fully charged

Do not store the batteries fully charged

Follow manufacturers instructions for charging and discharging rates

Store the batteries in a fire proof case with a latch

Never use a pack that has visible damage, dents or cracks

Charge the batteries in a fire proof safe or something similar

Do not charge the batteries with your hood open. While it is possible to use your car battery to power the charger if there is a problem with the battery the fire will consume the battery, charger and your car

If the battery is puffed up,  stop using it and follow the instruction so that you get rid of it safely

This is how I store and charge Lipo batteries

All of my batteries are stored in this case with the latch shut when they are not being used. I take this case or another smaller case to the flying field.

Foam liner this case allows for quick access to the batteries at the field or at home

These are 2S batteries the small 800 Mah is used with a RC park flyer while the 5000 Mah is used on my larger CL scale models

You can tell the voltage of the battery by the number of wires, this is 3S battery with one ground and three colored wires

This can be repaired, but I am not going to attempt it. There is a circuit board below the plastic cover and the wire needs to be re-sodlered to the board
