The ProTek R/C 4S 120C Graphene + HV LCG 4100mAh LiPo Battery is a great battery option for any racer looking for a lightweight, 4S battery. Weighing 345 grams, the LCG 4S is over 200 grams lighter than a standard 4S pack, providing improved power to weight ratio and a lower overall CG that makes it perfect for shorter qualifying races and "1/8 scale light" e-buggy classes.   


When compared to standard LiPo and LiHV, Silicon Graphene cells deliver improved efficiency, lower operating temperatures, lower internal resistance, better run time, increased cycle life and increased voltage - but Graphene + 120C LiPo batteries take that a step further with more power and lower internal resistance when compared to the previous ProTek LiHV Graphene packs!


Lab testing has shown that ProTek R/C Silicon Graphene packs have double the cycle life when charged at 1C rates, and can be charged at higher amp rates, with less risk of damage to the pack. More importantly, the discharge curve is flatter, meaning the cells maintain higher voltage throughout the discharge cycle with no significant drop off. Additionally, when compared to conventional LiPo batteries Silicon Graphene batteries are lighter, providing a higher capacity per gram ratio. With 7.6V nominal voltage, 120C discharge ratings, incredibly high charge rates and ten different models to choose from, ProTek R/C 120C Graphene + packs are perfect for racers and bashers that demand the absolute best.


NOTE: These batteries are designed specifically for 4S racing and bashing applications. These are not recommended for high current 8S setups, as damage to the internal circuit board is likely to occur.  

ProTek RC 4S 120C Si-Graphene + HV LCG LiPo Battery (15.2V/4100mAh)

SKU: #PTK5101


    Lighter than a hardcase 4S LiPo pack of equal capacity

    Improved power to weight ratio and a lower overall CG

    More runtime, with a dramatic increase in voltage and punch

    Silicone Graphene can handle more abuse and deliver more current than a standard LiPo battery

    Improved efficiency, lower operating temperatures, and lower internal resistance!

    Increased run time, increased cycle life and increased voltage!

    More capacity gram for gram when compared to standard LiPo cells

    Perfect for stock class racers looking to shave grams

    10C max charge rates - 1C charge rate recommended for longest life

    7.6V nominal voltage

    5mm bullets and 5mm to 4mm bullet adapters included


    NOTE: While these batteries are LiHV cells, they can still be charged the same as a standard LiPo with a standard LiPo charger. The overall voltage and capacity will be slightly less than when charged to LiHV specs, but the performance will be better than a standard LiPo thanks to the flat discharge curve, reduced weight, and low internal resistance. When charged to 8.4V, these packs will still offer a noticeable advantage when compared to a standard 7.4V LiPo pack.

    (1) ProTek R/C Battery



    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 overheated 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 the 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.
