4S 90C Si-Graphene HV LiPo battery with XT60 plug ProTek RC (15.2V, 1400mAh, 70x34x30mm, 150g)

ProTek RC 4S 90C 1400mAh Si-Graphene+ HV LiPo – Ultralight, compact & powerful

The ProTek RC 4S 90C 1400mAh Si-Graphene+ HV LiPo battery was specifically developed for applications where space and weight are critical —such as FPV drones, airplanes, or competition crawlers . Despite its compact dimensions of just 70 × 34 × 30 mm, the battery delivers plenty of power while weighing just 150 g !

That's about 15 g less than comparable 1300mAh 4S LiPos , but with more capacity – for longer runtimes and a better power-to-weight ratio. When charged to LiHV specifications , the battery delivers up to 17.4 V instead of the usual 16.8 V – ideal for more pulling power and a consistently high voltage throughout the entire discharge .

Advantages of Si-Graphene+ technology:

Compared to standard LiPo and LiHV cells, Silicon Graphene batteries offer:

• Higher efficiency

• Lower operating temperatures

• Low internal resistance

• Constant voltage throughout the entire discharge

• Longer running times & improved cycle stability

• Higher capacity per gram of weight

Laboratory tests show: 1C charging doubles the battery life . Even at higher charging speeds, the risk of cell damage remains significantly lower. The flat discharge curve ensures consistent performance down to the last mAh .

Features:

• Only 150 g – approx. 15 g lighter than a comparable 1300mAh 4S LiPo

• Compact format: 70 × 34 × 30 mm

• 15.2 V nominal voltage , up to 17.4 V at HV charging

• 90C discharge rate for maximum current output

• Ideal for drones, airplanes, competition crawlers, scale models and much more.

• More capacity per gram than standard LiPos

• 2C max. charging current , 1C recommended for longest life

• High voltage, stable performance, long service life
