This is the ProTek R/C "Supreme Power" 2S - 7.4V, 5600mAh, 100C Lithium Polymer hard case "Square" battery pack, with 5mm Bullet Connectors. With increased capacities and cell chemistry that delivers improved reliability, ProTek R/C 100C LiPo batteries are guaranteed to satisfy. Whether you are a racer looking for maximum power, or a basher looking for extended run time, these 100C packs provide the power and run time that enthusiasts demand. Plus they are backed by ProTek R/C, so you can buy with confidence knowing that we have your back.

This "Square" style battery pack is a great option for applications that use a side by side saddle pack setup, such as 2wd buggies and stadium trucks. When compared to a saddle pack, the square design eliminates the need for a jumper wire for increased efficiency, and at the same time cleans up your charging station by eliminating cluttered charging cables. This battery pack 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! This battery is not yet ROAR approved, but uses the same hard plastic case that is required for use at ROAR sanctioned tracks and events. A set of 5mm bullet connectors and a 2mm bullet connector are included.

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 11.2A!

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 2S "Supreme Power" Li-Poly 100C Hard Case Square Battery Pack (7.4V/5600mAh)
Awesome battery to use in my Team Associated B5RM but the only complaint is the supplied 5mm bullets are really, really tight, I have to use pliers to remove. If this issue was corrected then it would be perfect.)

ProTek RC 2S "Supreme Power" Li-Poly 100C Hard Case Square Battery Pack (7.4V/5600mAh)
Great battery! Fits nicely in my TLR 22 SCT where I used to run a saddle pack setup in both rear motor or mid motor config. Plenty of run time and always has the power to finish the race in front.)
