PTK-LIPOSAFE, ProTek RC Flame Resistant LiPo Charging Bag (Large, 23x30cm) This is a ProTek R/C Flame Resistant Lithium Polymer Charging Bag, and is intended to reduce the chance of damage or injury in the event of a LiPo fire. The ProTek LiPo Safe Charging Bag is rated up to 30 watt-hours and is made of high tech space-age materials that will help to contain a lithium polymer battery fire. Place your lithium polymer battery inside the LiPo Safe Charging Bag and extend the charging wires through the top flap. Charge your LiPo batteries in the LiPo Safe Charging Bag for peace of mind and a higher level of safety. In the event of a lithium polymer battery mishap, the LiPo Safe Charging Bag’s fire-resistant material reduces the severity of the fire inside and vents the smoke outside the LiPo Safe Bag. The Charging Bag is sealed with a thick, industrial strength Velcro flap and can also be used for safe transportation and storage of your Lithium Polymer batteries. Due to the volatile nature of Lithium chemistry batteries, charging bags such as the ProTek Lithium Polymer Flame Resistant Storage Bag are required by many tracks, flight clubs and at ROAR sanctioned events.  WARNING: Never leave charging battery unattended  Always ensure the battery is on a non-flammable surface  Ensure flap is sealed while charging  This ProTek R/C lithium charging bag is intended to reduce the chance of damage in the event of a LiPo fire Not recommended for batteries exceeding 30 watt-hours  Instructions: Ensure that charger rate is properly set and polarity is correct Attach charging leads to battery Place battery toward the bottom of the LiPo Safe Bag Place the LiPo Safe Bag on a non-flammable surface Route charge leads through either vent at the sides of the flap top seam of the LiPo Safe Bag Close top flap of the LiPo Safe Bag and press hook and loop closure fully closed Charge battery using proper charging practices Dimensions: 230x300mm (9x11.8 inches) This product was added to our catalog on December 16, 2021

PTK-5129-19, ProTek RC 2S 100C Si-Graphene + HV LiPo Stick Pack TCS Battery (7.6V/5000mAh) The ProTek R/C 2S 100C Si-Graphene + HV LiPo Stick Pack Battery is built using a hard plastic case that is the same dimensions as a standard NiMH stick pack. This makes them a great choice for Tamiya TCS Series racing, including Euro Truck, all GT classes, M-Chassis and Formula One - as well as Euro Truck Racing League. Plus, its a great choice for any chassis that will accept a 6 cell NiMH stick pack. Weighing in at 235 grams, this Si-Graphene + HV battery weighs less than a standard 5000mAh LiPo battery of the same configuration - making your car lighter and faster! When compared to standard LiPo and LiHV, Silicon Graphene cells deliver improved efficiency, lower operating temperatures, lower internal resistance, increased run time, increased cycle life and increased voltage - but Graphene + 100C LiPo batteries take that a step further with more power and lower internal resistance when compared to the previous ProTek LiHV Graphene packs! This provides more runtime, and a dramatic increase in voltage and punch over the course of a run.   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, 100C discharge ratings, incredibly high charge rates and huge variety of models to choose from, ProTek R/C 100C Graphene + packs are perfect for racers and bashers that demand the absolute best.   Features:  Perfect for Tamiya TCS Series racing Hard case is the same dimensions as a standard NiMH stick pack Lighter than a hardcase 2S LiPo pack of equal capacity  Improved power to weight ratio and a lower overall CG More runtime, with a dramatic increase in voltage and punch 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  Perfect for stock class racers looking to shave grams 10C max charge rates - 1C charge rate recommended for longest life 7.6V nominal voltage Factory installed T-style plug 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. Battery Model 2S HV LiPo ROAR Approved Yes  Type Silicon Graphene   Voltage 7.6V nominal  Capacity @7.4V  5000mAh  Capacity @7.6V  5400mAh  Weight  235 g  Connector Type  T-style Balance Connector  3 Pin XH Number of Cells 2 Cell  Configuration 2S1P  Dimensions (WxLxH) 46.7x137.5x24.2mm  Maximum Charge Rate 10C (50A)  Burst Current  100C  Watt Hour @7.6V  38Wh  Includes: (1) ProTek R/C Battery LITHIUM POLYMER SAFETY INFORMATION  IMPORTANT:  DO NOT leave the battery in your model when charging DO NOT leave unattended when charging  ALWAYS balance charge the battery  ALWAYS use a LiPo charging bag  YOU MUST use a Li-Poly specific charger to charge the pack (NiMH or NiCD only chargers WILL NOT WORK!)  YOU MUST not over discharge the Li-Poly battery pack 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.
