This is the ProTek R/C "Supreme Power" 2S 5000mAh, 35C Lithium Polymer hard case battery pack. This battery is ROAR/IFMAR approved and built using a hard plastic case that is required for use at sanctioned tracks and events. The packs are thin enough to fit into all touring cars and off-road vehicles.

These ProTek R/C battery packs can be used in any application where you need 6-cell NiMH stick or race packs, such as 1/10th scale electric touring cars or 2wd and 4wd off-road vehicles. These packs are significantly lighter when compared to regular NiMH race packs. This makes the overall vehicle weight lighter for significantly improved acceleration. These batteries also have a nominal voltage of 7.4V compared to the 7.2V of regular NiMH batteries, and have dramatically reduced internal resistance. This leads to increased top speed and improved 'punch' off the line when compared to NiMH batteries.

Note: Some vehicles may require some re-balancing if the light weight of these batteries cause some handling changes. To get the vehicle to balance correctly, add some weight to the battery side of the vehicle.

Unlike most other Lithium Polymer batteries, these batteries can be charged at up to 2 times the rated current, or 2C! If your charger is capable, you can charge these batteries at 10A!

 

Specifications:

  • ROAR Approved!
  • Type: Lithium Polymer
  • Capacity: 5000mAh
  • Voltage: 7.4V nominal
  • Connector Type: 4.0mm bullets with 2.0mm for balancing
  • Number of Cells: 2
  • Weight: 283g
  • Configuration: 2S
  • Dimensions (WxLxH): 46.9 x 139 x 23.2mm
  • Maximum Charge Rate: 2C (10A)!
  • Maximum Continuous Discharge: 35C (175A)
  • Maximum Burst Discharge: 70C (300A) for 3 seconds

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 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.

I've got three of these including two 40c's. They seemed like good value at the time but despite caring for them they all puffed quick quickly, one so bad it split the hard case. I have been using Lipos for years and these are the first that have ever puffed on me. I always balance charge at 1C, never get anywhere near the ESC cut-off and they had only been used for TC racing with low power motors (540's and 21.5) so it's not like they have been overworked. All the other brands I use are fine. Unfortunately I live overseas so won't risk mailing them back. Before puffing up they performed great, if anything the voltage is a bit higher than 7.4 and that equals speed with brushless.

A great battery to use for 2wd off-road vehicles. Plenty of power and the run time to top it off. The weight is a perfect medium for 2wd buggy, short course, and truck which allows the vehicle to be comfortable to drive and allow for more mid corner steering over heavier batteries. I would definitely recommend this battery for the great performance and durability, all for a good price.

Got two of them. Both work fine, but one is puffed. This product is not bad for bashing but bad for racing.

Ran my first ever on road race with one of these. Walked away with the top spot in the class. Never had a problem, and had plenty of run time for more then i gave it.
