LiPo battery products End User Agreement - JAG Precision


End User Agreement

Read this document in its entirety before using any LiPo battery product.

By purchasing and using our Lithium Polymer (LiPo) battery product, you, the end user, agree to educate yourself on the use of LiPo batteries and to responsibly use this product with the correct supporting equipment. You accept that it is your responsibility to use the correct charger, follow correct procedures for charging, operating, maintenance, storage, and disposal of the battery product. Should you fail to do this, it will result in a fire hazard. Adult supervision is required to charge and maintain LiPo battery products.

The manufacturer shall not be held liable for resulting damage caused by abuse, modification, neglect, or incorrect use of a LiPo battery product. Use Echo1 LiPo batteries only with approved Echo1 chargers and battery bag.
Why A LiPo Battery

  • Lithium Polymer (aka LiPo) batteries offer higher performance compared to conventional NiMH batteries, especially when used in electrically powered airsoft guns
  • LiPo batteries have greater energy density in a given volume, and therefor can offer more capacity in a compact package. This might be a necessity for airsoft guns with no room for standard sized batteries.
  • LiPo batteries are safe to use for frequent outings and is also commonly used in other hobbies such as radio controlled toys and drones, however their energy density also makes it more volatile and hazardous when misused or damaged

Use the CORRECT Charger

You can identify a LiPo battery by the two plugs coming out of the pack.
Charge using the balancing port. The balancing port will consist of a smaller JST connector and is exclusively used to charge. If your charger does not have a port to accept a JST plug, chances are you do not have the correct charger.
Do not use the incorrect type of charger such as one meant for a NiMH battery. Using the incorrect charger will result in a fire.


Identifying a LiPo Battery

There will be two plugs present:


Charge In Safe Area Inside Flame Proof Container

Only charge LiPO batteries on a nonflammable surface such as tile or concrete and not within 20 feet of any flammable materials. Use a Lipo safe bag or a fire proof container such as a metal bucket while charging.

Overcharging or attempting to charge a damaged battery pack could result in a fire. Although smart chargers have automatic shutoff features to prevent overcharging a battery, you should never leave the battery pack unattended while charging. It is your responsibility to monitor your battery while charging. If the pack becomes unusually hot to the touch during charge, unplug and do not use the pack.


Things to Know: Important Use and Care Information

  • If this is your first time with your new LiPo battery, charge it before use. LiPo batteries do not come fully charged and will not have adequate energy stored out of the box to use in your airsoft gun. Please properly charge before using any LiPo batteries or you risk damaging it prematurely.
  • Use a LiPo specific smart charger. It will charge to the correct voltage for you.
  • LiPo batteries must be used with LiPo compatible chargers only
  • LiPo batteries will have two plugs: the bigger plug will be the output port to be plugged into the airsoft gun and the smaller plug (JST) is to be plugged into a LiPo charger
  • LiPo voltage must be observed and maintained within a certain range to ensure battery pack life and performance. Overdischarging a LiPo battery or leaving it plugged in and having it drain to below 3.0V per cell results in permanent damage to the pack.
  • If you are unsure of the battery voltage or are do not have the ability to check, use as normal but stop using the battery when you begin to notice your electric gun is starting to cycle slower. Do not let the battery voltage drop below 3.4V per cell
  • A charged LiPo battery should not exceed 4.2 V per cell.
  • If a LiPo battery pack begins to look puffy or bloated, it is starting to show signs of damage and should no longer be used. Do not store or attempt to charge puffy Lipo batteries. Dispose of it properly.
  • Shorting out the battery will result in the battery getting damaged. It will get hot and could present a smoke and fire hazard. Unplug immediately and do not attempt to use until the problem is located and fixed. If your gun has an internal malfunction or improper modifications, it could cause a short as will improper modification to the battery pack itself. Exposed wires touching conductive material can also result in a short.
  • Store batteries at a voltage of 3.6 to 3.8V per cell when not in use. Do not store fully charged as it will degrade the cells faster and reduce capacity very rapidly. Check periodically and charge to storage voltage as needed.
  • Battery performance and life is significantly reduced when subject to extreme cold or heat. Use the battery in a temperature range of 40-90*F (5-32*C)
  • If a battery gets warm from usage, allow to cool before charging or using again. Do not maintain sustained bursts with your airsoft gun.
  • Do not allow wires to become damaged or exposed, and do not allow live wires to come into contact with any conductive materials
  • Do not drop or puncture the battery
  • Inspect the condition of your battery periodically for physical damage on the pack, wires, and plugs

How to Charge a LiPo Battery *Step-by-Step*

  1. Observe ALL aforementioned safety precautions listed in this document prior to charging.
  2. Inspect battery pack for any damage to wires, plug, or the pack itself prior to charging and use. Do not proceed if there is any damage or the battery pack is puffy/bloated.
  3. Read the charger instructions. Charger operation vary by manufacturer. A typical charger with have a light or lights to indicate when the charger is in operation or the charge cycle is complete. Make sure that your charger is set to charge LiPo batteries if it comes with multiple functions.
  4. Plug your LiPo charger to a wall outlet.
  5. Plug in your LiPo's charging plug (the JST plug) to the charger. Your charger's indicators should change to reflect charging status. Some chargers might also require you to plug in the other plug (Tamiya-style or Deans/T-Plug) to the charger to monitor temperature or utilize other features. Do not simultaneously plug both plugs EVER unless the charger instructions specify that you must do so. Observe all manufacturer provided instructions.
  6. Charge time varies due to different charger output and battery capacity (mAh/milliamp hours) - do not leave unattended and check periodically to make sure the pack does not get hot or start puffing or smoking.
  7. When the charge cycle is complete and all cells are at 4.2V, the charger should switch to trickle mode and stop charging further. Unplug the battery from the charger as it is now ready for use.


Please recycle used and damaged LiPo batteries. charge the cells as much as possible. DO NOT throw in the trash.

Used primary and secondary (rechargeable) batteries contain a high percentage of reusable substances and recoverable resources. By ensuring their recovery through appropriate recycling processes instead of combining them with common waste materials, you make a contribution in preserving important resources and protecting the environment from harmful heavy metal substances.
