6) YOU MUST not over discharge the Li-Poly 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.

a cheap bat pak for my 450, was not recommended by my fellow flyers, lasted about 50 flights (2 months) before it started puffing. Using a Onyx 235 for charging. You Get What You Pay For.
bot a EcoPower 5000mA hard case a couple of years ago and still using in my Slash ?

EcoPower "Electron" 3S LiPo 30C Battery Pack (11.1V/2200mAh)
Impressive lipo's for the price, plenty of punch for my 450 heli during semi aggressive 3d maneuvers, after 5 mins at 90% throttle curve im putting back in 1100-1300 mah which is perfect! Im also able to charge these at 2C, but I only choose 4.0a max charge rate during balance. Excellent battery's, thanks Amain!

EcoPower "Electron" 3S LiPo 30C Battery Pack (11.1V/2200mAh)
I'm a long time user of amain's "orange lipos" for surface and air. They're a good value and, until recently, they never failed me.

I purchased several ECP-LP-2200-3S30 batteries for use with my 350QX and VisionAire. Both ship with eflite/parkzone 25c/30c batteries. The ECP-LP-2200-3S30 batteries performed well in the 350QX but they are wholly inadequate for aggressive 3D flying in the VisionAire (using APC 13x4e prop at 5250ft). On several occasions during 2-5 second sustained hovers the battery petered out. When this happened at low altitude with no room to recover, it resulted in two major crashes. The second being a total loss of the aircraft, the first broke the BL10 shaft, ruining the motor. The problem happened with the OEM VisionAire motor EFLM7225 BL10, a power 15 and a power 25. I was able to reproduce the problem on the bench with a power 25 while metering the amp output of the battery to the motor. At full throttle, the battery would burst up to near 38 amps. Over the course of 3-6 seconds, the amperage would drop by approx. 50% per second until the SC shut down to keep the battery from failing. The problem does NOT occur with a 60c (ECP-LP-2200-3S60) battery which has the same initial burst of around 38c but drops by 5-10% per second and never gets below 30 amps. Perhaps this is related to being in CO at at 5200ft or because I'm using a 13x4e (OEM is 12x4)? I contacted Amain and they confirmed they haven't seen any other similar failures from the batteries. I've since moved on to the 60c version of this battery ECP-LP-2200-3S60 and I haven't been able to reproduce the problem on the bench or in the field. Moving forward I will avoid the 30c orange batteries for flight applications.

EcoPower "Electron" 3S LiPo 30C Battery Pack (11.1V/2200mAh)
On March of this year I took a chance on buying 2 of these batteries since no online store had lipo's with these specs in stock and since I'm recently returned to RC, first planes now helicopters, after many years of absence I wanted to get as much flight time as I could.

After 3 months and about 20 cycles on one pack and 21 cycles on another pack these batteries are doing great, with my other batteries, after about 6:30 min of flight time, the cells are in the 3.71 v range, while with these batteries all the cells are in the 3.83 v range.

Also, I always balance charge my batteries and these batteries balance out great, even with my cheap charger all the cells balance out at 4.20 v.

As a final thought, I feel that my helicopter flies more stable with these packs, maybe the weight of the packs balances out the heli much better than my other packs also the power transition from the motor is a lot smoother; perhaps it's just me but all I can say is that my heli feels a lot more stable when running with these lipo's and for someone who is learning that is very important.

I will definitely buy more of these batteries, just wish thy came with XT-60 connectors.

Perfect battery for anyone with a Vaterra Twin Hammers or other space constrained vehicle. Lots of power, purchased many Ecopower lipos never had a puffing issue,only one dead cell which amain replaced promptly.Think too many people charce at too high a rate. They say 1c people!

I have over 50 charges with this battery (balanced every time) and it always balances out perfect. I've used it in my T3, my T4, and now my Trex 450. I have to say this battery has been awesome, I plan to buy more.

EcoPower "Electron" 3S LiPo 30C Battery Pack (11.1V/2200mAh)
I have a single ecopower 3s30. after about 7 cycles in a very small buggy with , proper attention to voltage and discharge rates, I now have a puffy battery.

Weirdly enough it just puffed on the shelf. It was not in use or charging at the time.

I do not recommend this battery.

I ordered 2 of these...1 of them did not even make it through 10 cycles. The other one is still working but I have barely used it...hesitant to buy any more "EcoPower" batt's.
