The ProTek R/C 2S 120C Low IR Graphene + HV LCG 4600mAh Shorty LiPo Battery is a great battery option for any racer looking for a lightweight, shorty style battery. Weighing 165 grams, the LCG shorty is over two ounces lighter than a standard shorty pack, with a smaller footprint. This offers an improved power to weight ratio and a lower overall CG. 

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.  


Features:

  • Lighter than a standard shorty pack, with a smaller footprint
  • 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
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.

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.

ProTek RC 2S 120C Low IR Si-Graphene + HV LCG Shorty LiPo Battery (7.6V/4600mAh)
IR much higher than in my 7600 stick and 6100 shorty packs. Have never seen sub 2 milliohm values.

ProTek RC 2S 120C Low IR Si-Graphene + HV LCG Shorty LiPo Battery (7.6V/4600mAh)
These batteries have been great. The price is reasonable, the performance seems as good as anything on the market. They are a 5 star product.

A couple of poor reviews for this product because of users who either committed error when charging or didn’t take the time to look at the product photo to understand where the positive port is located. Their one star reviews are not a reflection of the product, but rather a reflection of the user.

ProTek RC 2S 120C Low IR Si-Graphene + HV LCG Shorty LiPo Battery (7.6V/4600mAh)
It works great. It is a little awkward trying to mount these lower batteries as my battery strap in my b5m doesn't go that low. They have plenty of juice in them for what I do.

ProTek RC 2S 120C Low IR Si-Graphene + HV LCG Shorty LiPo Battery (7.6V/4600mAh)
I got three off these a few months ago and disappointed the capacity when measured on my Icharger is only around 3300 . The IR is never below 3’s .

ProTek RC 2S 120C Low IR Si-Graphene + HV LCG Shorty LiPo Battery (7.6V/4600mAh)
Really solid performance. I.R. numbers are already really good after only the first handful of cycles. Felt great in my 13.5 4wd buggy,zero fade during my runs. Best protek packs yet

ProTek RC 2S 120C Low IR Si-Graphene + HV LCG Shorty LiPo Battery (7.6V/4600mAh)
Recently picked up a couple of these to try out. They work great. I thought I was in trouble when I realized the + and - were opposite from my Reedy batteries but the. I flipped the battery over and realized it has plugs in the bottom that can be remived so that the + and - work like other batteries. I can easily go 6 minute mains with no fade. They are shorties so you will need to adjust your battery hold down if you don’t normally run shorty batteries. I might grab a couple more of these since they are fairly cheap.

ProTek RC 2S 120C Low IR Si-Graphene + HV LCG Shorty LiPo Battery (7.6V/4600mAh)
Very dissappointed that this pack has the leads reverse polarity from every other lipo on the planet. Yea it can be run upside down with pass through bullets (except balance lead) , still not good, at all.

Not racer friendly, I literally dont care if this pack runs the best out of all my packs (I doubt it) I will still never trust it

Leads reversed should be in the name of the pack

ProTek RC 2S 120C Low IR Si-Graphene + HV LCG Shorty LiPo Battery (7.6V/4600mAh)
I just purchased 2 of these batteries recently and have been very impressed so far. The fit and finish are excellent, and the low profile design works very well. The performance has been outstanding so far. These batteries are punchy and the runtime has been better than I expected. Very flat discharge curve with no fade. If these ProTek batteries continue to do well I will definitely purchase more in the future. At $59 I think they are a good value.
