ProTek RC 4S Shorty 120C Low IR Silicon Graphene+ HV LiPo Battery (15.2V/6000mA) w/5mm Connector (Pending ROAR Approved)

The ProTek R/C 4S Shorty 120C Low IR 5600mAh Silicon Graphene+ HV Battery is a great option for 1/8 scale racers looking for a high capacity, high output and incredibly COMPACT 4S battery. Weighing approximately 425 grams, the 4S Shorty is almost 50 grams lighter than the PTK-5118-20 5600mAh 4S pack with more capacity! This offers more capacity output, in a compact shorty length that is perfect for weight conscious racers.   

ProTek R/C Silicon Graphene batteries are the next step in the evolution of LiPo battery technology. Silicone Graphene construction offers improved efficiency, lower operating temperatures, lower internal resistance, better run time, increased cycle life and increased voltage!

When compared to standard LiPo and LiHV, Silicon Graphene cells deliver an array of benefits! 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, 100C discharge ratings, incredibly high charge rates and ten different models to choose from, ProTek R/C Silicon Graphene packs are perfect for racers and bashers that demand the absolute best. 

While these batteries are technically LiHV cells, they can still be charged with a standard LiPo charger. The overall voltage and capacity will be slightly less than if charged to LiHV specs, but the performance will be better than a standard LiPo thanks to the reduced weight and low internal resistance.

NOTE: This battery is not recommended for high current draw 8S applications

• (2) 5mm Bullet Connectors 
• (1) 4S Balance Lead 

IMPORTANT: 
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 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.
