1) DO NOT leave the battery in your model when charging
2) DO NOT leave unattended when charging
3) ALWAYS balance charge the battery
4) ALWAYS use a LiPo charging bag
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 flight 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.

ProTek R/C is an AMain Sports & Hobbies brand.

I bought 5 of these batteries for use with a BNF Basic mSRX kit. I don't have experience with the stock 150mAh batteries nor any others so I dont have good comparison other than avg flight times people have posted on forums. I get about 5-7 minutes of air time which consists of lots of hovering and scooting around the hangar bay of the boat I'm on when the real helos are off flying. They have an interesting "power curve" where they fly for about 3 minutes with no noticeable loss of power then there is a sudden drop where I have to add just a little more juice for the second half of the flight until right before the LVC kicks in it starts to feel flat. I charge these lower than 1C because my charger only adjusts in .1 amp increments and I always round down when charging (it ranges from charging 1 to 5 batteries at once in parallel depending on how much flying I do). Would I buy them again? Yes. Would I buy them over Turnigy batteries? Yes mainly because A Main has great CS so if I get a dud (which I feel is less likely than a HK batt) I can ship it back without paying out the nose for a $5 battery.

Good battery. I use these in my nano cp x and fly mostly hard 3D. I get about 6 1/2 to 7 minute flights charging at .3amps.

These batteries seem to work great! Nice long flight times, great power. I use them in my mcx and mcx2. They are longer than stock and to keep the CG right you have to push them all the way towards the front and they may interfere with the servos. I stuck a sliver of fuel tubing between the landing skids and the frame to give it more room.
