This is the ProTek R/C "Sport Race" 2S 4200mAh, 40C Lithium Polymer hard case stick 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. These "Sport Race" battery packs are built using a hard plastic case that is the same dimensions as a standard NiMH stick pack, which makes them a perfect fit in any chassis that will accept a 6 cell stick pack, such as 1/10th scale electric touring cars or 2wd and 4wd off-road vehicles. These batteries are also an excellent option for starter boxes, as they will easily fit into battery trays that were designed for 6 Cell stick packs.

Additionally, these packs are significantly lighter when compared to regular NiMH race packs. This makes the overall vehicle weight lighter for dramatically 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 improved top speeds and '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. Additionally, when used in starter box applications, we recommend that you convert the plugs on the starter box to the Traxxas style connector.

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 8.4A!

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.

IMPORTANT:
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.
