This is the ProTek R/C "Supreme Power" 4S - 14.8V, 6700mAh, 100C Lithium Polymer hard case battery pack, with 5mm bullet connectors. 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.

100C discharge rates, combined with 6700mAh capacity allow this pack to deliver the all the punch you can handle, with the run time you need for long races. This battery is ROAR approved and built using a hard plastic case that is required for use at sanctioned tracks and events, and uses 5mm bullet connectors for an ultra low resistance connection. An integrated 5-Pin XH connector is built into the end of the case to provide compatibility with one of the most common types of balance connection. 


  • Includes 5mm Bullet Connectors that must be soldered on to your ESC.
  • 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 13.4A!

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 35C 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.
