This pack includes includes an integrated balance charge lead with a Deans style T-plug installed for a convenient connection capable of handling extremely high amp rates. While the 3-pin Align/E-Flite style XH balance connector provides compatibility with one of the most common varieties of balance tap connection.This battery can be used in any application where you would use a 6-cell NiMH stick or race pack, and are significantly lighter when compared to regular NiMH packs. This makes the overall vehicle weight lighter for significantly improved acceleration. These batteries also have a nominal voltage of 7.4V compared to the 7.2V of regular NiMH batteries, and have dramatically reduced internal resistance. This leads to increased top speed and improved 'punch' off the line.
- When used with Traxxas 2S applications, you must use the optional extended battery strap.
- When used with Traxxas 2S applications, you must install an adapter for the Traxxas High Current Connector (PTK-5228).
- Some vehicles may require some re-balancing if the light weight of these batteries cause some handling changes. To get the vehicle to balance correctly, add some weight to the battery side of the vehicle.

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.

I have since purchased some of the Protek 100C batteries and there is definitely a difference in performance. I still recommend though for someone getting into the sport or hobby to buy the Ecopower batteries first. Until you understand the whole concept of charging and discharging LIPO batteries properly I would not buy expensive batteries just in case you damage a battery. Plus I wouldn't have been able to tell the difference between the Ecopower and Protek batteries when I first started racing because I could not consistently hold the truck straight and get on the throttle hard.)
Sometimes economy does not turn out to be so economical.)
Now. My battery lasted me exactly two years before it started swelling. It didn't hold full voltage after a charge for half the time probably. But it didn't seem to care. It seen hundreds of cycles during the time it was alive. So for the amount of yard bashing I did, it withstood for quite a while. I used the ecopower charger as well.)
