ProTek RC 4S 90C Si-Graphene + HV LiPo Battery (15.2V/1800mAh) w/XT60 Connector

Battery Overview:

The ProTek R/C 4S 90C 1800mAh Si-Graphene + HV LiPo Battery was developed for drones, airplanes comp crawlers - or any application where space is at a premium and light weight is critical. These micro-sized packs are incredibly lightweight and shoehorn a ton of power into a compact 86.5x33.5x27.5mm form. Everything from FPV race drones, airplanes and high-performance comp crawlers can benefit from the performance these packs deliver.

About the 4S 90C Si-Graphene LiHV Battery Pack

High-Performance LiHV Power

In addition to its small size, this featherweight pack comes in at just 175 grams, and is over 25 grams lighter than a comparable LiPo battery. Plus, when charged at LiHV specs, this battery produces 17.4V instead of the standard 16.8V of a fully charged standard LiPo, meaning performance-oriented enthusiasts can take advantage of the light weight, and higher voltage throughout the discharge curve to give them a more consistent power delivery.

Silicon Graphene Cells

Want more reasons to run this pack? When compared to standard LiPo and LiHV, Silicon Graphene cells deliver improved efficiency, lower operating temperatures, lower internal resistance, better run time, increased cycle life and increased voltage, but Graphene + LiPo batteries take that a step further with even more power, more capacity, and lower internal resistance!

Lightweight Design & Reliability

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 15.2V nominal voltage, 90C discharge ratings, incredibly high charge rates and ten different models to choose from, ProTek R/C Graphene + packs are perfect for enthusiasts that demand the absolute best.

IMPORTANT LITHIUM POLYMER SAFETY INFORMATION

• DO NOT leave a battery in your model when charging
• DO NOT leave lithium batteries unattended when charging
• ALWAYS balance charge lithium battery
• ALWAYS use a LiPo Safe charging bag/box
• YOU MUST use a Li-Poly specific charger to charge lithium batteries (NiMH or NiCD only chargers WILL NOT WORK!)
• YOU MUST not over discharge lithium battery packs
• 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 overheated 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 the 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 temperatures 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 it until it has cooled completely. Wait about 20 mins, then inspect prior to recharging.
