The ProTek R/C 3S 100C Silicon Graphene HV Shorty LiPo Battery was developed specifically for 1/10 scale rock crawler and rock racer applications. 3S packs that are commonly used in the crawler world are either small, low capacity packs - or large, heavy 4000-5000mAh packs. This 3600mAh battery fills the void and gives scalers a higher capacity option that produces more voltage and longer runtimes than a 2200mAh, yet only weighs approximately 20 grams more! Plus, when charged at LiHV specs this battery produces 13.05V, instead of the standard 12.6V of a fully charged standard LiPo, meaning U4 racers can take advantage of the light weight, and higher voltage throughout the discharge curve to give them a more consistent power delivery with less fade on the track!

Want more reasons to run this pack? When compared to standard LiPo and LiHV, Silicon Graphene cells deliver an array of benefits! Silicone Graphene construction offers improved efficiency, lower operating temperatures, lower internal resistance, better run time, increased cycle life and increased voltage. Lab testing has shown that ProTek R/C Silicon Graphene packs have more than 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. Additionally, when compared to conventional LiPo batteries Silicon Graphene batteries are lighter, providing a higher capacity per gram ratio. With 11.4V nominal voltage, 100C discharge ratings, incredibly high charge rates and increased power, ProTek R/C Silicon Graphene packs are perfect for scalers and racers that demand the absolute best. 

NOTE: 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. 


  • Comparable weight to a 2200mAh pack, 100g lighter than EcoPower 4100mAh
  • Great choice for scalers and U4 racers
  • Great choice for boats and airplanes too
  • 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
  • 11.4V nominal voltage

  • (1) ProTek R/C Battery w/T-Style Connector


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.

ProTek RC 3S 100C Silicon Graphene HV Shorty LiPo Battery (11.4V/3600mAh)
I have to say this little battery is bar far the most impressive little power house I have ran to date. The extra voltage of the LiHV gives it one kick in the pants for power, not to mention the run time on a single charge. I was fortunate enough to have two of these at Axialfest 2017 to keep me going for hours. I got over 450 gates out of one battery in medium trail to heavy rock. The most Iv gotten out of one of these in a brushless 1.9 RC crawler on medium to technical trails was 3 solid hours and knew voltage cut off was close but never hit it. SBC rates this battery 5/5 stars

ProTek RC 3S 100C Silicon Graphene HV Shorty LiPo Battery (11.4V/3600mAh)
I bought one of these for my bomber as it was eating 2200 packs for lunch.

All I can say is wow! This thing packs a punch and gives amazing run times even when blasting at full throttle. First run was the other day and it outlasted everyone on the trail even after a dozen or more full throttle hill climb runs at the end of the trail run.

Do yourselves a favor and get one.

ProTek RC 3S 100C Silicon Graphene HV Shorty LiPo Battery (11.4V/3600mAh)
Killer, killer battery. I was able to run over 500 gates on one charge during Axialfest! The battery also has killer "snap" as well. I was able to replace 2 of my Prior 2200mah 3s batteries with a single one of these. Less batteries to charge and carry around!

ProTek RC 3S 100C Silicon Graphene HV Shorty LiPo Battery (11.4V/3600mAh)
ProTek RC 3S 100C Silicon Graphene HV Shorty LiPo Battery (11.4V/3600mAh)I was super excited when I first found these, because one of them outlasted and out performed two 2200mah 3S lipos of another brand and was more compact too. However, after 3-6 months they have let me down. 3 out of 4 of them have puffed despite babying them unlike any lipo/lihv I've ever had, one is to the point of super puffed! I've had better luck with much cheaper batteries! I emailed AMain and they didn't respond for several days (even though website says reply in 24hrs or less), so I called A-Main. They gave me a partial store credit, better than nothing, but nowhere near offsets the cost of 4 of these batteries especially with tax and shipping. I used to recommend these nice compact, lightweight, powerful LIHVs to everyone, but now I'm very disappointed and can no longer recommend these batteries.

I'm looking for some compact, thin 3S batteries to fit in TF2 stock location.

ProTek RC 3S 100C Silicon Graphene HV Shorty LiPo Battery (11.4V/3600mAh)
The battery is a great size, and was perfect for one of my projects, however, as others have found, it failed quickly. It started to puff after 4 cycles, and shortly after one of the cells died completely. Very disappointed for such an expensive lipo pack.

ProTek RC 3S 100C Silicon Graphene HV Shorty LiPo Battery (11.4V/3600mAh)
This battery is just great, love that its LIHV and it fits perfectly in the front battery tray for a trx4 bronco. I got 4 hours out of this pack on Sunday and it was still going when we left. Definitely my go to pack for crawlers now.
