Product Description
This is a Li-Poly 2600mAh receiver battery hump pack from ProTek R/C, made with super thick 20awg silicone wire! This super light weight Li-Poly battery is designed to power the electronics of 1/10th & 1/8th scale gas powered race cars. Overall weight of your race car will be significantly reduced over the use of typical NiMh receiver packs. The battery voltage to your receiver and servos will remain constant throughout the race with the use of a voltage regulator (required). A constant voltage for your servos will ensure consistent performance at the start and end of the your race compared to typical NiMH receiver battery packs.
These packs are built with a lexan plastic shell around the outside of the battery, and then covered in blue heat shrink. The lexan shell is designed to protect the battery cells while in the vehicle, for longer life. Note that due to the lexan shell, sometimes the battery may feel soft to the touch on the outside of the battery; this is normal as there is a small air gap between the lexan shell and the battery cells inside.
Runtime:
Don’t be thrown off by the capacity rating of Li-Poly battery packs, as you will get awesome runtime out this pack! Unlike NiMH battery packs, Li-Poly battery packs do not lose voltage as quickly over time and can handle higher current draw than typical NiMH battery packs. Given that Li-Poly battery packs provide a higher nominal voltage (7.4V nominal), the actual capacity of the battery pack when compared to a typical NiMH battery pack (6.0V nominal) is about 30% more than the rated value (so this pack would be about the same as a 3000mAh NiMH pack in total capacity). Also with the use of a voltage regulator, Li-Poly battery packs will produce the same voltage to your receiver and servos at the end of the pack as it does at the start. This means the useable capacity of the battery pack is significantly more than typical NiMH battery packs, because most NiMH battery packs will produce significantly less than the 6.0V nominal voltage once they get below half capacity (ie: your servos will be a lot more sluggish if your typical NiMH battery pack is below half capacity).
Why must Li-Poly receiver packs be used with a voltage regulator?
Although the Li-Poly battery pack’s nominal voltage is 7.4V, when it is fully charged the voltage output is 8.4V. The 8.4V output exceeds the safety level of most receivers and servos on the market, so you must use a voltage regulator with these Li-Poly receiver packs to decrease the voltage to safe levels that your receiver and servos can accept.

Voltage: 3.7V
DO NOT leave the battery in your model when charging - DO NOT leave unattended when charging
- ALWAYS balance charge the battery
- ALWAYS use a LiPo charging bag
- YOU MUST use a Li-Poly specific charger to charge the pack (NiMH or NiCD only chargers WILL NOT WORK!)
- YOU MUST not over discharge the Li-Poly battery pack
- READ & UNDERSTAND the instructions carefully before operating this battery
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.
