Key Features

• 140C extreme discharge rate: Blistering acceleration, lightning-fast throttle response, and robust current delivery for competitive heats
• Ultra-low profile NGP Shorty design: 18.5mm thin hardcase lowers the vehicle center of gravity (CG) for superior cornering and chassis balance
• Gold-plated 5mm bullet ports: Direct-plug female bullet sockets ensure minimal resistance and maximum electrical conductivity
• Graphene cell technology: Enhanced thermal dissipation, ultra-low internal resistance, and durable cycle longevity under demanding race schedules
• Included 5mm bullet charging harness: Complete with flexible silicone power leads and selected connector (XT60, EC5, TRX, Deans/T-Plug, XT90, XT150, or Q8S) plus JST-XH balance lead
• Grade-A matched cells: Rigorously factory matched for cell voltage balance, low IR, and consistent lap-after-lap power

180-Day Warranty & Customer Support

Every DXF battery is backed by a 180-day manufacturer warranty against defects in materials and workmanship. DXF customer support is readily available for guidance on connector compatibility, charging parameters, and battery maintenance.

Usage & Safety Guidelines

• Use a dedicated balance charger supporting standard 2S LiPo (4.20V/cell) balance charging.
• Always balance charge inside a fire-resistant LiPo safety bag and never leave charging batteries unattended.
• Do not overcharge past 4.20V per cell or discharge below 3.2V per cell.
• Store batteries at 3.80V–3.85V per cell in a cool, dry, ventilated location away from direct sunlight.
• Inspect the hardcase, 5mm bullet harness, and terminals before every race session.
• Never puncture, drop, crush, short-circuit, or expose the pack to extreme temperatures or water.
• Verify vehicle battery tray dimensions, polarity markings, and ESC voltage compatibility before operation.
