Overview

E-flite® Thrust® VSI (Voltage Status Indicator) Series lithium polymer batteries feature an integrated voltage checker so you can check the status of your battery on the go. A series of LED lights will indicate the state of charge at the press of a button. Compact E-flite® Thrust Series lithium polymer batteries are rated at 40C to deliver excellent power and longevity without a major size or weight penalty. Each battery is equipped with popular EC3™ (EFLB50006S40 is equipped with an EC5) and JST-XH balance connectors compatible with a wide range of chargers (such as those from Dynamite and Orion®) and ESCs, and they’re available in a variety of capacities and cell counts for use in park flyers up to large airplanes, helis and drones.

WARNING: Lithium Polymer (Li-Po) batteries come partially charged and are significantly more volatile than the alkaline, Ni-Cd or NiMH batteries used in RC applications. Keep batteries out of reach of children, unless supervised by a responsible adult. All interactions and warnings found on the sheet inside of this card must be followed exactly. Mishandling of Li-Po batteries can result in a fire. Before handling and first use, visually and physically inspect the battery pack, wire leads, and connectors to ensure there are no loose connections which may cause short circuit and eventual fire. By handling, charging or using this Li-Po battery you assume all risks associated with Li-Po batteries.

FAQs

LI-PO Do's and Don'ts

DO: Use a charger that is specifically designed to charge Li-Po batteries. Using chargers that are not Li-Po-specific can be an extreme fire hazard.

DO: Li-Pos don't develop memory or voltage depression characteristics like Ni-Cds. Charge them without the worry of cycling or discharging them first.

DO: Store Li-Pos at least partially charged. Li-Pos will maintain their performance levels over time, even during non-use, much better than Ni-Cds, and there's no need to cycle them.

DON'T: Never fully discharge your Li-Po battery pack. Most electronic speed controls have a voltage cutoff that will prevent over-discharging the battery, but were designed for Ni-Cd & Ni-MH batteries. Be sure that your ESC features the proper Li-Po cut off voltage of 3V per cell (6V for 2-cell packs, 9V for 3-cell packs and so on). Discharging a Li-Po cell beyond its critical minimum voltage will cause damage to the battery.

DON'T: Shorting a Li-Po pack for even an instant can cause damage to the battery. Whether the pack has been shorted when new, while adding or changing the connector, when fully charged or fully discharged, the pack should not be charged without extreme caution. Be sure to take care when soldering connectors and during handling or charging to prevent shorts.

DON'T: If you have a crash and the battery is damaged, don't put the battery in your car or house immediately after a crash. It's possible that a chemical reaction can take place in the damaged battery that could cause a fire. Put the battery in a safe place for at least one hour.

What is a typical Li-Po pack's voltage?

Li-Po packs are available in 2- and 3-cell varieties (Thunder Power packs are also available in 4-cell and 5-cell models). Each cell in the pack has a nominal voltage of 3.7V and multi-cell packs are wired in series.

2-cell pack = 7.4V

3-cell pack = 11.1V

4-cell pack = 14.8V

5-cell pack = 18.5V

What is the "C" rating for?

A "C" or "current" rating indicates the maximum recommended average discharge current for that pack and is used to help you determine the maximum discharge rate. To determine the maximum discharge rate, multiply the "C" rating by the pack capacity (i.e. 1900mAh cell x 6C rating = maximum discharge rate of 11,400mA or 11.4A).

What is the "S" number for?

The "S" number indicates the number of cells in series. For instance, 2S indicates a 2 series (2-cell) pack.

What is the "P" number for?

Larger packs use the "P" number to indicate the number of cells in parallel. For instance 3S2P indicates the pack is built with 2 cells in parallel, then 3 sets of the 2 parallel cells are joined in series.

Can I use my regular peak charger to charge Li-Po packs?

Li-Po batteries require a very different charge method than Ni-Cd or Ni-MH cells and can catch fire if charged with a standard, non-Li-Po charger. Li-Po batteries do not "peak" when fully charged and require a "constant current/constant voltage" capable charger.

Why are some models available with or without a JST connector?

JST connectors have become the standard on many electronic speed controls and chargers for slow flyer and park flyer applications. While it's true that the JST connector does have a discharge output limitation, it is still the first choice of beginning modelers or those who do not discharge at very high rates.
