Enerland / POLYQUEST LiPo's

POLYQUEST 20c, 25c and 30c LiPo Batteries!

300mah 20c Packs...

2150mah 25c Packs...

PREMIUM LiPO Batteries from POLYQUEST! - Best? All Poly-Quest "Twenty" brand lipoly packs can be discharged at a rate 20 times their capacity. Example: a 1200 mAh (1.2 Amp hour) pack can be discharged at 24 amps and a 3700 mAh pack at 74 amps continuous. This is NOT the peak discharge rate; it is the rate that these packs can be discharged at CONTINUOUSLY. "Twenty-Five" brand lipo packs can be discharged at a rate 25 times their capacity.

All PolyQuest packs 800 mAh and larger have a connector that plugs into a balancer/charge guard. Our ETC505 Balancer can be used to keep the cells in your battery balanced and will prevent you from destroying your battery by accidental overcharging. Overcharging can ruin your battery and cause a fire. PolyQuest's unique welding process allows packs to put out more power, and the packs have better between-cell ventilation which gives longer pack life. Poly-Quest packs are ventilated.

What you should know about Lithium Polymer Batteries
Lithium Polymer batteries have specific charging requirements and ONLY chargers designed to charge Lithium Polymer batteries may be used. Please do not charge your lithium polymer at any rate higher than 1C. Doing so may reduce the capacity and life cycle of the cells, with very little savings in charge time. Safety precautions for charging Lithium Polymer batteries include:
  • Double check the Lithium Polymer charger settings for the battery pack being charged - both voltage and current settings.
  • Charge batteries on a surface that can withstand heat and is not prone to catch fire. A wooden table is not recommend.
  • Do not charge batteries near flammable items or liquids.
  • Do not charge inside your model. The materials used in model airplanes are highly flammable and or temperature sensitive.
  • Do not charge inside an automobile, especially while driving.
  • Do not use water to extinguish a battery fire. Keep a dry fire extinguisher nearby. Do not try to fight any fire. If you cannot stop a fire immediately, call the fire department.
  • Do not charge a battery that appears to have "ballooned" due to over or under charging.
  • Do not store batteries in an automobile.
  • Do not peak charge or "top off" lithium polymer batteries.
  • If you crash your model, check your battery first. Do not try to charge a damaged battery.

    Storage & Handling: New cells may have a high initial charge, and care must always be taken to insure that single cells are not short-circuited.

  • Do not put the single cells in a pocket, bag, or drawer where they could short-circuit against other items, or the battery tabs could be pressed against each other.
  • Do not place the single cells on any conductive surface, such as a metal-topped table.
  • Keep single cells and battery packs WELL out of reach of children!
  • Take care that especially metallic objects like knives or scissors do not puncture the cells.
  • If the electrolyte in the cells should get on your skin, thoroughly wash with soap and water. If in the eyes, rinse thoroughly with cool water. Immediately seek medical attention for this.
  • Store batteries in a dry cool place away from flammable materials.
  • Store batteries in a fireproof container.

    Important Notice
    All sales of Lithium Polymer batteries are FINAL. This means we will not accept returns on Lithium Polymer batteries for any reason. As used in R/C applications discharge rates exceed the manufacturer's specified maximum rates for these cells. Therefore, the use of Lithium Polymer batteries in radio-controlled models is to be considered experimental, and there is no warranty, expressed or implied, with respect to the capacity, life in cycles, storage, or discharge characteristics of cells in RC use, nor any other use nor aspect. We strongly suggest you use a safety guard component with these cells. Lithium Polymer batteries hold a huge amount of energy and must be respected. We can NOT accept any responsibility for the use of Lithium Polymer battery products. Your use of this product means you accept our terms and you are fully responsible for any consequences.
