The ProTek R/C 4S 100C Low IR 5600mAh Silicon Graphene HV LCG LiPo Battery is a great battery option for anyone looking for a high capacity, high output COMPACT 4S battery. Weighing 470 grams, the 4S HV LCG is 90 grams lighter than the 6500mAh 4S pack, with a 10mm lower overall height. This offers high capacity output, in a compact package perfect for weight conscious racers.   

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.


  • Lighter and smaller than the PTK-5106-17 4S pack
  • Great 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
  • 10C max charge rates - 1C charge rate recommended for longest life
  • 15.2V nominal voltage
  • Replacement XH4S balance adapter also available separately (PTK-5331)

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.

ProTek RC 4S 100C Low IR Silicon Graphene HV LCG LiPo Battery (15.2V/5600mAh)
Worked great for a year. I always charged at the specified rates and always put into storage mode after running. Started by taking a long time to charge and then the next time I went to put the battery on charge from it being in storage mode gave me a voltage error and now it wont charge at all. Talked to customer support and the best they could do was a $20 in store credit. Not to great for a $160+ battery that only lasts a year with about 15 race weekends on it. If you are ok with replacing your lipo every year then this is the battery for you

ProTek RC 4S 100C Low IR Silicon Graphene HV LCG LiPo Battery (15.2V/5600mAh)
I was skeptical about buying this brand of battery. I should have known better. The battery didn't last 6 months and I only charged it at 1c a few times. One of the cells is pretty much dead and useless. Should have gone with the Reedy.

ProTek RC 4S 100C Low IR Silicon Graphene HV LCG LiPo Battery (15.2V/5600mAh)
My first battery was doa. If arrived, I put it on a shelf and got called to work. Fast forward 4 months, I go to get my stuff ready and commission this proteck battery and it had a bad cell. I was worried because I was outside the warranty period. I almost did not engage them but a guy in our rc group said I should. So I did and they made good on it! Sent me a new battery. So I've been letting everyone know that Amain has integrity which is often hard to come by. I will be making all my major purchases with Amain, and will advise my friends too!

ProTek RC 4S 100C Low IR Silicon Graphene HV LCG LiPo Battery (15.2V/5600mAh)
So far so good with both packs I bought. Running them in a 8ight XE with tekin rx8/1900kv. I've ran each pack 15-20 full runs in the past few months. No puffing, great power all the way to the end, about 15-20 minutes run time minimum, and I love the weight being lower with these. The first 5-7 runs, I never let them drain beyond 50% and I balance charged them slow

ProTek RC 4S 100C Low IR Silicon Graphene HV LCG LiPo Battery (15.2V/5600mAh)
Purchased for use in Mugen MBX8 ECO. The LCG Battery is a perfect fit and has clearance to spare using the kit body. Easily lasts during 10 minute Mains.

ProTek RC 4S 100C Low IR Silicon Graphene HV LCG LiPo Battery (15.2V/5600mAh)
One of the best 8th scale batteries on the market... A little on the pricey at first but when you run them for a few races you find its worth the $$$. The lower profile battery is a must in my opinion.

ProTek RC 4S 100C Low IR Silicon Graphene HV LCG LiPo Battery (15.2V/5600mAh)
I picked up a pair of these 5600mah Protek packs in August of 2020 with my new TLR 8ight-XE Elite kit and Tekno EB48 2.0 kit. I bought 4 of the 6500mah 100c versions 2 years prior and liked them so much that when I got back into 1/10 scale a year ago I picked up 4 of the 6100mah 2s shorties for some new kits I built, and they have also worked awesome, so I needed to leave another great review for the Protek LiHV packs. I dont have a ton of cycles on these newer ones, but they still run as good as they did the first time I charged them so Im satisfied.
