Li-Po BATTERY SAFETY TIPS
AND BUYERS AGREEMENT
Please read the below statement. ~ Thank you.
|
PLEASE NOTE:
ALL Li-Po batteries must be charged with a dedicated Lithium Polymer charger ONLY. By selecting AGREE below, the potential buyer agrees to understand that there are risks, known and yet unknown, to the use of Li-Poly batteries in the R/C (radio control) hobby, and is willing to accept these risks as his/her own responsibility. |
- • Only use chargers designed specifically for Lithium Polymer battery.
- • Double check the charger, number of cell selection setting, and mAh before every charge.
- • Only charge the batteries on a non-flammable non-conducting surface, such as bare cement floor.
- • Do not charge the battery inside the model plane, inside of ones car, home furniture or wood floor/carpet, or anywhere near flammable material.
- • Monitor the charging of the battery pack at all times and do not leave the battery unattended.
- • Place a fire alarm above the Li-Poly battery charging location. Follow the fire alarm installation instructions.
- • After a crash, inspect the battery pack for damage. Discard the pack outdoors if there is any sign of damage.
- • Store the pack fully charged in a cool and dry location and out of reach of children.
- • If storing for a month or more, discharge to 70-80% capacity.
- • Do not assemble packs in series into parallel packs as mismatch could result in fire.
- • Do not store Lithium Polymer battery inside a car.
- • Do not short the battery as it may catch on fire. If accidentally short a battery, place it in open space and observe the battery for 10 minutes. It may swell up and possibly even catch on fire.
- • Do not discharge Li-Poly battery below voltage according to the number of cells in series in the following chart.
Before charging, your Lithium Polymer should have these minimum voltages (Check battery pack voltage before charging.):
|
S = Series, P = Parallel |
Minimum voltage |
1 Cell 1SXP
|
3.0V |
2 Cells in series 2SXP
|
6.0V |
3 Cells in series 3SXP
|
9.0V |
| 4 Cells in series 4SXP |
12.0V |
Check your charger for safety. After charging, check battery with a digital volt meter. Once fully charged, the voltage should read between MINIMUM and MAXIMUM of these numbers:
|
Number of Cells |
Minimum full charge |
Maximum full charge |
1 Cell
|
4.16V |
4.23V |
2 Cells in series
|
8.32V |
8.45V |
3 Cells in series
|
12.48V |
12.68V |
| 4 Cells in series |
16.64V |
16.9V |
Maximum discharge: Do not discharge your Lithium Polymer battery below the maximum discharge voltage for Li-Poly cells and packs of the NO LOAD and LOADED voltages as seen below:
|
Number of Cells |
No Load
(Motor not running) |
Loaded
(Motor running) |
1 Cell
|
3.0V |
2.5V |
2 Cells in series
|
6.0V |
5.0V |
3 Cells in series
|
9.0V |
7.5V |
| 4 Cells in series |
12.0V |
10.0V |
There may be a slight chance the battery pack could combust due to unmatched cells in capacity or voltage, damaged cells, charger failure, charger setting errors or many other factors.
Buy purchasing these products, buyer understands the risk associated with the use of this experimental product, will take the necessary precaution for its safe use and hold the manufacturer, seller, all affiliates and agents harmless in case of damage, injury or death. Buyer is solely responsible for any damage or injury resulting from the use of this experimental product.
There is no warranty implied or expressed on Li-Poly battery and packs, as the intended use of these batteries in RC airplane application is beyond the design specification of the manufacturer.
By purchasing Li-Poly battery products listed below, buyer fully understands the delicate nature of this battery and risk associated with this product, and agrees with the terms and conditions listed above.
Please note there is no warranty on lithium polymer batteries once they are used due to the experimental nature of their use. If there are any question, please contact us before purchasing this product. Our email: sales@pencenaround.com |
