This ProTek R/C "Supreme Power" 100C Shorty LiPo Battery Pack is ROAR/EFRA/IFMAR approved and built using a hard plastic case that is required for use at sanctioned tracks and events. The battery features 2C charge rates and 5mm bullet connectors, with a set included, as well as an included 2mm connector. Plus, a set of 5mm to 4mm adapters are included so you can continue to use your 4mm charge leads to charge your battery!

This "shorty" style battery pack is perfect for any application that can benefit from the reduced weight of a smaller battery, and uses 5mm bullet connectors for an ultra low resistance connection. In fact the battery tubes can be accessed from either side of the case, allowing you to position the battery terminals in the direction that best suits your application!

Hi-Voltage Capable
This specially formulated battery features LiHV technology which allows the cells to safely reach a higher overall voltage (4.35V per cell vs standard 4.20V per cell). Achieving the higher voltage does require a LiHV capable charger, but the power gains are significant to the overall punch and power for the model. This battery can also charge and function perfectly at typical 2S voltages (8.4V), but please note: cell voltages exceeding 4.20V per cell is prohibited from sanctioned racing rules, such as ROAR, IFMAR, etc. 

Features: 

  • Lightweight Shorty Pack
  • 100C Discharge Rate

  • Hi-Voltage LiHV Capable
  • Durable 5mm Bullets
  • ROAR Approved

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 a 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 100C Hard Case Shorty LiPo Battery Pack (5mm) (7.4V/4250mAh)
This is a great battery. It has great punch and overall holds its power well throughout each charge. Also for stock racing, it can withstand 40a charging. I love this battery. 5 stars.

ProTek RC 2S 100C Hard Case Shorty LiPo Battery Pack (5mm) (7.4V/4250mAh)
I purchased 3 of these packs last year to cycle in my 17.5 B5m and 6.5 powered HB D413. After around 150 cycles i have had one finally swell a small amount. The batteries were balanced at 12 amps every charge and stored properly, even with the amount of use and abuse they've seen they still balance perfect (iCharger), provide plenty of punch and minimal fading during long mains. Overall I'm very satisfied with my purchase and the performance from these. Im going to be ordering 3 more and put my current ones into retirement.

Bought 2 in April. Great power and balanced fine. They puffed pretty much beyond fitting in my battery tray by August. We're used in 17.5 buggy.

ProTek RC 2S 100C Hard Case Shorty LiPo Battery Pack (5mm) (7.4V/4250mAh)
Great batteries while they last. I had two packs which puffed after a half-dozen carefully monitored runs with 1C charges. Incredibly disappointing. Fortunately, AMain has EXCEPTIONAL customer service and took care of everything. Bad cells are bad luck. It happens. Buying from AMain makes the difference! ProTek makes good equipment, but my pair of faulty ones forces me to hold it to 3 stars for questionable product consistency.

ProTek RC 2S 100C Hard Case Shorty LiPo Battery Pack (5mm) (7.4V/4250mAh)
Excellent pack and a great value. I own four of them. All of the packs have been treated excellently but there is a reason Protek is nicknamed Pufftek. All four of these packs have swelled after about an average of six cycles. The packs are still running strong but the puffing is a bit disconcerting.

ProTek RC 2S 100C Hard Case Shorty LiPo Battery Pack (5mm) (7.4V/4250mAh)
This is the second time I bought these batteries. And both times the performance was the same. With this particular battery when ran it starts off at 4.18 per cell and after a run it comes off at 3.98 per cell. Which is actually pretty good. However, when new, the battery is is perfectly flat at about 25mm of thickness. After only about 10 charges the battery swelled to 30mm. In both cases when buying a protek battery they both tend to swell after a few charges.

Purchased 2 of these and they were doing great for a few charges, lots of power. But noticed both batteries starting to swell with less than 10 charge cycles. Batteries were never discharged below 7.2V

Very good packs. Great punch! Would have received 5 stars if it came with a charge cable like another very similar battery of a different brand.

These packs are awesome. Low resistance and great heat resistance/tolerance. They come to life quick right after a few cycles and are super punchy.
