This is the ProTek R/C "Supreme Power" 2S - 7.4V, 3200mAh, 100C Lithium Polymer hard case battery pack. 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 that 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.

This 100C pack is the same size as our 1S Li-Poly pack, but is a 2S battery, making it perfect for 2S pan car applications. It is slightly smaller and has a lower capacity than our 4700mAh Shorty pack, but is 67 grams lighter! The reduced weight and size of this battery makes this pack an excellent choice for not only pan cars, but also any application that would benefit from a smaller size, high energy, lightweight 2S battery. This battery is ROAR/EFRA approved and built using a hard plastic case that is required for use at sanctioned tracks and events. It is thin enough to fit into all pan cars, and includes two 4mm bullet connectors, and a 2mm bullet for balancing.

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 6.4A!

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.
