This is the ProTek R/C "Sport Race" 2S 5000mAh, 25C Lithium Polymer hard case battery pack. This battery features a genuine Traxxas High-Current Connector® for the ultimate in efficiency, ease of use and high current handling capabilities for charging/discharging and a 3-pin Align/E-Flite style XH balance connector for balancing. Although these are not ROAR approved hardcase batteries, they are built using a hard lexan shell to help prevent damage in the event of a crash.
These ProTek R/C "Sport Race" battery packs can be used in any application where 6-cell NiMH stick or race packs are required, such as 1/10th scale electric touring cars or 2wd and 4wd off-road vehicles. These packs are significantly lighter when compared to regular NiMH race packs, reducing the overall vehicle weight for significantly improved acceleration. Li-Poly batteries also have a nominal voltage of 7.4V compared to the 7.2V of regular NiMH batteries, and have much lower internal resistance. This leads to better top speeds and improved 'punch' off the line when compared to NiMH batteries.
Note: Some vehicles may require re-balancing, as the reduced weight of these batteries may cause handling changes. To get the vehicle to balance correctly, add weight to the battery side of the vehicle.
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 up 10A!
CRASH Protection Guarantee!
ProTek RC offers a 50% Damage Replacement program for one (1) year after original purchase date on all batteries that have been damaged due to impact, over-discharging, or improper charging that have not been modified or disassembled. The damaged battery will be replaced by a comparable battery at 50% off of its retail cost.

1) You will need a Li-Poly specific charger to charge the pack (NiMH or NiCD only chargers WILL NOT WORK!)
2) You must not over discharge the Li-Poly battery pack.
3) Read 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.
ProTek R/C is an AMain Sports & Hobbies brand.
