ProTek RC 2S "Supreme Power" Li-Poly 100C Hard Case Battery Pack w/5mm Bullets (7.4V/7400mAh)
This is the ProTek R/C "Supreme Power" 2S - 7.4V, 7400mAh, 100C Lithium Polymer hard case battery pack. With increased capacities and cell chemistry that delivers improved reliability, ProTek R/C 100C LiPo batteries are guaranteed to satisfy. Whether you are a racer looking for maximum power, or a basher looking for extended run time, these 100C packs provide the power and run time that enthusiasts demand. Plus they are backed by ProTek R/C, so you can buy with confidence knowing that we have your back.
This battery pack uses 5mm bullet connectors for an ultra low resistance connection. In fact the battery tubes can be accessed from either side of the case, allowing you to position the battery terminals in the direction that best suits your application! This battery is perfect for any application where you need 6-cell NiMH stick or race pack, such as 1/10th scale electric touring cars or 2wd and 4wd off-road vehicles. LiPo packs are lighter than NiMH packs, and deliver increased voltage with dramatically reduced internal resistance. These advantages provide reduced vehicle weight, increased top speed and improved 'punch' off the line compared to NiMH batteries.
This battery is ROAR/EFRA/IFMAR approved and built using a hard plastic case that is required for use at sanctioned tracks and events. It is small enough to fit into all touring cars and off-road vehicles. A set of 5mm bullet connectors and a 2mm bullet connector are included.
Note: ProTek R/C offers a 5mm to 4mm reducer so you can continue to use your 4mm ESC and charge leads (PTK-5005).
Unlike most other Lithium Polymer batteries, these batteries can be charged at up to 2 times the rated current, or 2C! If your charger is capable, you can charge these batteries at 14.8A!

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 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.

Amain simply offered the standard warranty of 50% off of a replacement. (Good to see they stand behind the product)...
Sorry, I've learned my lesson. I need parts that have more than a 50% chance of actually finishing a race. What a complete joke, to any semi-serious competitor....
-5 Stars, please. ProTek are the worst LIPO batteries I've ever used, and will NEVER go back. Using high spec's to drive up sales, and no consideration for any kind of reliability.
Look elsewhere if you are looking for similar spec's. ProTek LIPO is like betting on ODD at Roulette, because you have a 50/50 chance of losing EVERY time.)
2 batteries puffed, one cell doesn't t take 4.20 volts.....connectors are 5mm so bigger then all my others....
Protek products are not cheap and doesn't do better then cheap one.
It was not my first experience, and I was already not happy the first time.....
Forget the warranty.)
Using them several times per event, and will purchase more!
If you're having trouble with these packs puffing, you're probably not maintaining them properly.
Don't charge with a cheap quality charger, EVER.
Don't run them to cut-off, EVER.
Don't store them fully charged, or fully discharged, EVER.
Treat them right, they'll treat you right.)
