ProTek RC 2S "Supreme Power" LiPo 35C Hard Case Battery (7.4V/5500mAh) w/4mm Bullets

This is a ProTek R/C "Supreme Power" 2S 5500mAh, 35C hard case LiPo battery pack. This battery is built using a hard plastic case that is required for use at ROAR sanctioned tracks and events. The packs are thin enough to fit into all touring cars and off-road vehicles and can be used in any application where you need 6-cell NiMH stick or race packs. These packs are significantly lighter when compared to regular NiMH race packs for significantly improved acceleration 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 causes some handling changes. To get the vehicle to balance correctly, add 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!  Battery Model Supreme Power 35C ROAR Approved Yes Type Lithium Polymer Capacity 5500mAh Voltage 7.4V nominal Connector Type 4mm Bullet Balance Connector 2mm Bullet Number of Cells 2 Cell Configuration 2S2P Dimensions (WxLxH) 46.7x137.5x23.1mm Maximum Charge Rate 2C (11A) Continuous Discharge 35C (192.5A) Watt Hour 40.7Wh Weight 268g Includes:  (1) ProTek R/C Battery (2) 4mm Bullet Connectors (1) 2mm Balance Bullet Connector LITHIUM POLYMER SAFETY INFORMATION IMPORTANT:1) DO NOT leave the battery in your model when charging2) DO NOT leave unattended when charging3) ALWAYS balance charge the battery4) ALWAYS use a LiPo charging bag5) 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 pack7) READ & UNDERSTAND the instructions carefully before operating this batteryNOTE: 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.
