1) DO NOT leave the battery in your model when charging
2) DO NOT leave unattended when charging
3) ALWAYS balance charge the battery

5) YOU MUST use a Li-Poly specific charger to charge the pack (NiMH or NiCD only chargers WILL NOT WORK!)
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. 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.

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!

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.

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.

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.

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.
