We compare tray dimensions against verified battery dimensions, applying a 2mm tolerance for cable management and straps.

Label Definitions

• Spacer Required: The battery is notably shorter than the tray. A foam spacer or block helps prevent sliding.
• Voltage mismatch: The battery’s max charged voltage exceeds the car’s rated limit. Running it risks ESC or motor damage.
• Hard case required: Some tracks require hard cases for safety and compliance. Soft packs may fail tech inspection.
• Low voltage alarm recommended: The car isn’t LiPo-ready, so add an LVC alarm to avoid over-discharge.
• Adapter needed: The connector type differs. Use a quality adapter rated for the current draw.

We group compatible connectors (for example IC5/EC5 and Deans/T-Plug) to reduce false mismatches.

“Fits with mod” appears when only height fails and an expansion kit is available.

Wire-exit clearance varies by chassis. Always confirm lead orientation in photos.
