This is the EcoPower "Electron" 4S 2200mAh, 30C Lithium Polymer battery pack. Every hobby enthusiast is unique, each with their own specific needs and expectations. Not everyone needs a professional grade, high performance LiPo battery, while others simply don’t want to spend big bucks on the latest “flavor of the month”. The common thread between these customers is they both want a reliable and affordable battery that provides good runtime, good power and reliable performance, and AMain Sports & Hobbies is ready to deliver with EcoPower!

This battery will also make an excellent starter box battery for R/C Cars! You can significantly reduce the weight of your starter box, as one of these batteries will weigh less than one third of two 3600mAH NiMH packs (222g vs 802g). This will make your starter box almost 1.3 pounds lighter! Not to mention they will have increased voltage and punch, making it easier to start a tight engine.

EcoPower batteries are tested in house, allowing us to provide batteries that deliver accurate specifications and reliable power, at a price that is geared towards our value conscious customers. Plus, if we say it’s in stock, you know we have it. And when you buy it, we will back it up with the outstanding customer service and support that you have come to expect from AMain Sports & Hobbies. So stop beating yourself with cheap batteries, and buy from a trusted source that proves itself time after time with quality products at affordable prices! 

This pack has T-Style Ultra connectors pre-installed, and comes with a 4-pin Align/E-Flite style balance connector. This lightweight Li-Poly 30C battery pack is designed to fit radio controlled planes and helicopters that can use a 36x110x31mm, 4S 2200mAh battery pack.

7) READ & UNDERSTAND the instructions carefully before operating this battery

NOTE: When using high energy Li-Polymer Batteries, please do not over-discharge or over-charge batteries as this will result in over heated batteries. Discharging capacity can't exceed 80% of the max capacity of the pack after full charging to ensure a good cycle performance. It is recommended to fully charge a brand new battery before using and only discharge the battery 50% for first 5 cycles. Always monitor race time and/or set a low voltage warning on ESC (End voltage cannot be lower than 3.2v per cell) Do not use the battery that has too low a voltage.

Do not expose batteries to sunshine or store/charge batteries at the temperature above 35°C or in a closed car. The high temperature environment could cause damage to the pack or make it burst. If the battery becomes hot while fast charging, high current discharging or racing, do not charge the battery until it has cooled completely. Wait about 20 mins, then inspect prior to recharging.

EcoPower "Electron" 4S Li-Poly 30C Battery Pack (14.8V/2200mAh) (Starter Box)
I got one of these to test at IRCHA. My helicopter is a HDX 450 that was set up for 3S.
I changed the pinion, and put in a better ESC that could handle 4S.

The battery is almost the same size and weight as a 3S of brand X.
It has a Deans connector installed on a 4.5" 12AWG lead.
The balance connector is short and stays out of the way.
It balanced quickly and charged with no problems.

It changed my docile helicopter into a raging demon- still too much head speed, I need a slower motor now.
Anyway it had plenty of power, no sagging, and only a little warm after the flight.

This is a good battery.)

EcoPower "Electron" 4S Li-Poly 30C Battery Pack (14.8V/2200mAh) (Starter Box)
I bought two of these batteries. One performed well and the other not so well. Once I checked the readings on how much each cell is putting out I found out that one cell is near dead, reading 0.9v, on one battery. So thats 50/50 for me, waste of money.)

Excelente batería, recomendada, la comparo con una Pulse de 3000mah y esta EcoPower tiene mejor rendimiento, la uso en un quadracoptero DJI F450 y los resultados son geniales, buena calidad a bajo precio)

EcoPower "Electron" 4S Li-Poly 30C Battery Pack (14.8V/2200mAh) (Starter Box)
I purchased this battery at the beginning of the 2013 on season racing at Blue Diamond Park. This battery provides an enormous amount of power throughout two day race events plus another one day event the next week without requiring an additional charge. This single battery has dramatically reduced the weight of my starter box making trip to pit lane easier! All-in-All this is a GREAT battery and at this price it is a bargain!! I recommend this battery highly!!)

For the price you can't beat this deal with a stick. I bought this to use as a backup to my protek starter box batteries. I used it a few weeks ago and it performed very well.)
