Lithium Polymer Battery Packs

   

Electrics Tips and Tricks   

RC Model electric planes, boats and cars - Tips and Tricks.

WARNING
Safety precautions for Lithium Polymer
cells/packs stocked by Model Flight

 1. Never fast-charge any battery type unattended.
2. Never charge LiPo cells/packs at any rate unattended.
3. Only charge LiPo cells/packs with a charger designed specifically for lithium polymer chemistry. Example     chargers include the Kokam LIPO 402, and Schulze chargers with lithium charging capability.
4. LiPo cells can ignite because of unmatched cell capacity or voltage, cell damage, charger failure, incorrect charger settings and other factors.
5. Always use the correct charging voltage. LiPo cells/packs may ignite if connected to a charger supplying more than 6 volts per cell.
6. Always assure the charger is working properly.
7. Always charge LiPo cells/packs where no harm can result, no matter what happens.
8. Never charge a cell/pack in a model. A hot pack may ignite wood, foam or plastic.
9. Never charge a cell/pack inside a motor vehicle, or in a vehicle’s engine compartment.
10. Never charge a cell/pack on a wooden workbench, or on any flammable material.
11. If a cell/pack is involved in a crash:

a. Remove the cell/pack from the model.
b. Carefully inspect the cell/pack for shorts in the wiring or connections. If in doubt, cut all wires from the cell/pack.
c. Disassemble the pack.
d. Inspect cells for dents, cracks and splits. Dispose of damaged cells (see below).

12. Dispose of cells/packs as follows:

a. Discharge: with the cell/pack in a safe area, connect a moderate resistance across the terminals until the cell/pack is discharged. CAUTION: cell/pack may be hot!
b. Discard:

- NiMH: place in regular trash.
- NiCd: recycle (cadmium is toxic).
- LiPo: puncture plastic envelope, immerse in salt water for several hours, place in regular trash.

13. Handle all cells/packs with care, as they can deliver high currents if shorted. Shorting by a ring, for example, will remove a finger.
14. Always store cells/packs in a secure location where they cannot be shorted or handled by children.
15. When constructing a pack, use only cells of the same capacity (mAh).

 

Looking after the Environment

 

Model Flight believes in a sustainable earth and urge all our customers to use rechargeable batteries where possible. Please recycle your old flight packs and note that NiCad contains heavy metals that will poison the soil if thrown into the tip. They must be disposed of properly. NiMH are more environmentally friendly and can be disposed of in your normal rubbish.

Nicad NiMH Battery Care

 

When you first get your battery
Run your rechargeable battery through at least 3 full charge/discharge cycles before putting it into ordinary service. This will help obtain maximum capacity of the battery.

Storing your battery
Store your battery in a cool dry place. Do not leave your battery exposed to direct sunlight or temperatures below 30 degrees F and above 100 degrees F.  Always fully charge lead acid batteries before storing.

Charging your battery
Rechargeable batteries will perform better when trickle charged. Rapid or Fast charging can be used with NiCd, NiMH and Li-IOn batteries, but you must be sure that your charger can handle the cell chemistry involved.

Important: Most of the problems with rechargeable batteries can be traced to misuse.
