The Weight-Power Paradox
Every RC enthusiast knows the eternal struggle: more power means more weight, but performance demands both. For years, pilots and drivers compromised – accepting either sluggish response from lightweight packs or dealing with the inertia of high-capacity batteries. Standard LiPo solutions plateaued, leaving innovators trapped in a power-to-weight ratio that limited what micro-models could achieve.
The ProTek R/C 3S 90C 1400mAh Si-Graphene + HV LiPo Battery shatters this compromise. At just 115 grams – 15g lighter than conventional LiPos – it delivers higher voltage (13.05V at LiHV charge), lower internal resistance, and a discharge curve that maintains power like a sprinter holding form through the finish line.
Three-Layer Breakthrough: What Makes This Battery Different
1. Physical Architecture
The compact 70x34x22.5mm form factor defies expectations, packing 1400mAh capacity into a space smaller than most smartphones. The XT60 connector ensures robust power transfer, while the optimized cell arrangement lowers the center of gravity – critical for flight stability and crawler performance.
2. Silicon-Graphene Chemistry
Unlike conventional LiPo batteries, the silicon-graphene hybrid anode material provides 3-5x higher lithium ion capacity. The graphene matrix prevents silicon expansion issues while enhancing conductivity. This translates to lower internal resistance (reducing heat buildup) and the ability to sustain 90C bursts without voltage sag.
3. High Voltage Advantage
When charged to LiHV specifications (4.35V/cell), the battery delivers 13.05V – nearly half a volt higher than standard LiPos. This “voltage headroom” means ESC systems run cooler, motors maintain RPM under load, and pilots experience more consistent power throughout the discharge cycle.

Where the Rubber Meets the Sky: Real User Transformations
FPV Racing: The Pylon Turn Advantage
“In the final lap of our regional championship, I was 0.8 seconds behind. Where my old batteries would sag in the high-G turns, the ProTek pack held voltage. That consistency let me carry more speed through the slalom – I won by 0.3 seconds. The weight savings meant I could run my heavier GoPro without penalty.”
– Marco T., Drone Racing League Finalist
Scale Crawling: The Hidden Weight Dividend
“For my 1/10 Land Rover Defender build, interior details are everything. With conventional batteries, I had to choose between runtime and interior space. The ProTek’s light weight let me add a full dashboard and seats while actually increasing run time by 18 minutes. The low CG makes side-hilling more stable too.”
– Sarah L., Scale Crawling Enthusiast
Aerobatic Planes: The Thrust Equation
“In my 800mm wingspan Edge 540, the 15g weight reduction equates to 6% less wing loading. Combined with the higher voltage, I get quicker spool-up and more consistent power in knife-edge passes. My vertical uplines gain an extra 15 feet before the energy bleeds off.”
– David R., IMAC Competition Pilot
From Frustration to Breakthrough: A Typical User Journey
Initial State
An FPV racer struggles with voltage sag in tight turns, forcing conservative throttle management that costs lap time.
Trigger Event
Critical race lost by 0.5 seconds – telemetry shows 11.1V drop during key maneuvers.
Struggle
Tries heavier batteries (worse handling), higher C-rating packs (minimal improvement), capacitor banks (added complexity).
Solution
Switches to ProTek Si-Graphene – gains both weight reduction and voltage stability.
Outcome
Next race: consistent power delivery allows aggressive cornering, 1.2s faster lap times.
The Verdict: Not Just Better, Different
The ProTek R/C 3S 90C Si-Graphene + HV LiPo Battery represents a paradigm shift rather than incremental improvement. By solving the core physics challenges of energy density and internal resistance simultaneously, it enables applications where conventional batteries forced compromise. For pilots, drivers, and builders who view every gram and volt as a performance variable, this isn’t just another battery – it’s a new design parameter.
