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.

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.

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! 

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.
