The ProTek R/C 2S 100C 4900mAh Silicon Graphene HV Shorty LiPo Battery is a great battery option for any racer looking for a high capacity, shorty style battery. Weighing 203 grams, the HV Shorty is lighter than a standard shorty pack, with a massive increase in capacity. This makes it an ideal pack for 2WD and 4WD modified racing, or stock class racers that want optimum voltage for the entire run. This pack is also a great choice for 1/8 e-buggies that want to run a lightweight 2x2S saddle pack configuration. 

ProTek R/C Silicon Graphene 100C LiPo 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.

"The SG packs are worth .1 to .2 tenths of a second per lap in the 17.5 classes because they have more punch and they don’t fade. They are legit!” - Randy Pike, Tekin Team Manager

"The power drop off is noticeably later in the run using the Silicon Graphene LiPo batteries. The IR rating keeps getting lower and lower with every cycle and the battery temp after a run is much lower than our old 100C packs." - Chad Bradley, ProTek R/C Product Specialist

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. Some sanctioned races have maximum 8.4V battery end volt requirements, and these packs will offer a noticeable advantage when compared to a standard 7.4V LiPo pack.

Features:

  • Ideal for 2WD and 4WD modified racing, or stock class racers that want optimum voltage for the entire run
  • Perfect for 1/8 e-buggies that want to run a light 2x2S saddle pack configuration
  • Improved power to weight ratio and a lower overall CG
  • 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
  • 10C max charge rates - 1C charge rate recommended for longest life
  • 7.6V nominal voltage

LITHIUM POLYMER SAFETY INFORMATION

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.

Best batteries available today in a shorty pack! Run them in both my 2wd buggy and 4wd buggy. Plenty of run time to make a 10 min race and more punch than you could ask for. They do not fade off like regular lipos either!

ProTek RC 2S 100C Silicon Graphene HV Shorty LiPo Battery (7.6V/4900mAh)
I have tried a lot of packs in my 17.5 buggy running on turf and carpet and this pack has been the best so far. It is light and can turn fast laps late in a run. Practicing on a layout where 15.6 was my fastest lap I hit a 15.9 on my 41st lap. Great pack!

ProTek RC 2S 100C Silicon Graphene HV Shorty LiPo Battery (7.6V/4900mAh)
I purchased three 4900 packs. Racing them two to three times a week. Performance has been good.

Unfortunately, one of them puffed noticeably within the first month. I contacted AMain and they handled the issue quickly.
Three months in, a second one has puffed. Not as bad as the first. I haven't contacted support on it yet, as it's not that bad yet.
The third looks like new.

Based on my experience, I would give AMain support five stars. The batteries, however, are more like a three. I'm not sure if I would buy them again. Would a different brand hold up better? Maybe. Would another company stand by their product as well? Maybe not.

ProTek RC 2S 100C Silicon Graphene HV Shorty LiPo Battery (7.6V/4900mAh)
Very disappointed with the Protek 2S - 4900 batteries. I purchased two less than a year ago and both batteries have dropped a cell in between normal useage. Though they were maintained in a storage state when not being used. We run a monthly points series where the batteries were used 1 raceday, or one weekend per month. Will be going back to another brand of batteries... I have two Orions 4500’s that are two years old and still going strong. So I know its not our useage or care of the batteries.

I’m very disappointed with these batteries. Less than 6 months old, I also barely use them, maybe once or twice a month, always balance charged and they puffed up during a race and now one Cell has gone bad.

My Orion batteries have lasted 2 YEARS so obviously I know how to take care of my batteries. I won’t be buying any more of these. How about a refund or exchange A-Main?
