Please read before charging or using your Li-Po battery
By purchasing Evo Power Lipo battery, the buyer assumes all risks associated with this product. If you do not agree with these conditions, please return the battery immediately before use.
Lithium Polymer batteries are volatile. Failure to read and follow instructions may result in fire, personal injury and damage to property if charged or used improperly.
Do not short circuit! Li-Po battery can be volatile under extreme duress. They can cause fire because they contain flammable chemicals. If a fire does start, do not attempt to put the fire out with water. It is best to use chemical (ABC, BC, CO2) extinguisher or sand to put out the Li-Po battery fire. Keep them near your charging station and your observation area.
Lipo batteries require care and attention both in use and during charging. Never charge or discharge your Li-Po battery unattended.
Evo Power Lipo batteries are not fully charged as you receive them. They contain approximately 50% of a full charge.
Use Lithium Polymer specific chargers and dischargers only. Failure to do so may cause a fire, which may result in personal injury and property damage. Always double-check the settings on your charger or discharger before using. Wrong settings can damage your battery and cause fire.
Some Li-Po chargers on the market may have technical deficiencies that may cause them to charge or discharge Li-Po batteries incorrectly. It is solely the responsibility of the user to assure that the charger used works properly.
Verify the Li-Po pack’s voltage of the pack using a digital voltmeter.
Never discharge Li-Po batteries to below 3 volts per cell and never charge at greater than 4.2 volts per cell. In many cases, a minimum 3.3V should be observed for the longevity of the Li-Po battery pack. Non-warranty damages will occur to the Li-Po pack if you discharge below 3V or charge above 4.2V. Damages so caused are not covered by warranty.
If any damage to the pack or leads is found, or the voltage is significantly less, do not attempt to charge or fly the pack; contact EVO POWER LIPO Battery as soon as possible.
After a model crash, carefully inspect the battery for damage and dispose of properly if damaged.
If a Li-Po battery starts to deform, swell or balloon, discontinue the charge or discharge Evo Power Lipo immediately. Disconnect the battery and place it in a safe observation area (area away from buildings, vehicles, and combustible material) for approximately 15 minutes. Continuing to charge a swollen battery may result in fire.
If for any reason you need to cut the terminal wires, cut each wire individually, so that the cutting tool does not create a short.
Accidentally short of the Li-Po battery through the wires, direct contact, keys, coins or ring often occur in the user’s pocket, tool box, bench tools and metal table. A shorted Li-Po battery must be placed in a safe observation area for approximately 15 minutes because a short can start an immediate or delayed chemical reaction.
All crash or shorted batteries (even if not deformed) should be placed in a safe area for observation for at least 15 minutes, because chemical reactions can be time delayed up to 10-15 minutes.
These internal chemical reactions often do not deform Li-Po batteries. However they can start chemical combustion or fire.
Avoid puncturing Li-Po battery as a damaged Li-Po battery may cause a fire.
Never attempt to charge at a rate faster than that recommended.
Charge on a safe surface or in a fire resistant container or a charging bag specifically designed for this purpose. Charge only on nonflammable and non-conductive surfaces, e.g. concrete, Pyrex cooking dish, or clay pot.
Do not charge a Li-Po battery inside a car.
NORMAL CHARGING: The charge rate should not exceed 5C (2C Recommended)
Remember Li-Po batteries do not store well fully charged nor fully discharged.
Try to adhere to a 80% rule…if you are using 1000mah battery, only use 800mah per use. Make it a habit to always monitor and keep track of what mah you put back in the packs after every charge and adjust flight times to keep you to the 80% rule. Your batteries will last you a lot longer if you adhere to this simple rule.
Lipo Batteries tend to get hot from two things; over discharge (using the full capacity of the battery) and overstress (exertion past the peak C rating). A battery will warm up as it discharges and get warmer and warmer as it approaches its cycle end (dead). Stay off the limits and your battery will last a long time.
Charging (Li-Po): 35 to 113 degrees F
Discharging (Li-Po): 35 to 140 degrees F Transportation
Li-Po, Short term storage (1 week or less)
For best results store Li-Po batteries between 40 and 80 degrees F.
Do not expose battery packs to direct sunlight (heat) for extended periods.
Storing Li-Po batteries at temperatures greater than 140 degrees F for extended periods of time (more than 2 hours) will cause damage to cycle life and possible fire.
Li-Po, Long term storage (longer than 1 week)
Li-Po batteries do not store well at fully charged nor fully discharged states.
Charge the battery for storage to 3.7v to 3.9v per cell (between 50 to 60%).
Re-charge them as necessary to keep them at 3.7v to 3.9v per cell.
Evo Power Lipo, batteries are environmentally friendly.
Physically undamaged Li-Po cells should be fully discharged before disposal.
Physically damaged Li-Po cells MUST NOT be discharge before disposal
The Li-Po batteries must be cool to the touch.
Place the Li-Po battery in a fireproof container or bucket of sand.
Connect the Li-Po battery to a specified Li-Po discharger. Set the discharge cutoff voltage to the lowest possible setting
Discharge the Li-Po battery until its voltage reaches 1.0V per cell or lower. For resistive load type discharges, discharge the battery for up to 24 hours.
Submerse the Li-Po battery into plastic bucket or tub of salt water (1/2 cup of salt per gallon of cold water). This container should have a non-airtight lid. Keep the Li-Po battery submerged in the salt solution for at least 2 weeks.
Remove the Li-Po battery from the salt water. Wrap the discharged Li-Po battery in newspaper or paper towels, and toss it as normal trash. They are landfill safe.
