Motor Pairing
Continuous discharge BMS current matched to your hub or mid-drive motor:
- QS205 V3 Hub Motor (3kW-8kW): Pair with 72V 40Ah / 50Ah (150A+ BMS) for instant wheel spin.
- QS138 70H / 90H Mid Motor: Requires 72V 50S high-discharge pack handling up to 200A continuous.
- MXUS 3K-Turbo / Leaf Motor: Pair with 72V 40Ah 50G pack for high-efficiency cruising.
Heavy-Duty Connectors
High-voltage anti-spark connectors prevent terminal arcing:
- QS8 Anti-Spark Connector: Standard on all BOOANT Stealth Bomber packs (handles 180A+ continuous).
- Anderson SB50 / XT90-S: Optional custom discharge plug configurations available.
- 8AWG High-Temp Silicone Wire: Flexible copper cabling for easy side-panel routing.
EEB Steel Box Fitment Guidelines
Standard Stealth Bomber and EEB steel frame boxes offer approx. 140mm Width × 200mm Depth × 360mm+ Height internal volume:
Because side panels bolt directly onto the frame, ensure EVA foam padding (3-5mm) is installed on both side walls to protect cell shrink wrap against steel panel vibration.
Frequently Asked Questions
Q: Will a 72V 60Ah pack fit inside a standard EEB steel frame?
A: Yes! Standard EEB frames feature a wide triangle compartment. BOOANT 72V 60Ah packs built with high-density Samsung 21700 cells fit within standard 140mm width limits while leaving clearance for controller wiring.
Q: Why is QS8 Anti-Spark mandatory for Stealth Bomber builds?
A: High-voltage 72V/84V packs store immense energy. Connecting without an anti-spark resistance plug causes violent electrical arcing, which melts connector pins and damages controller capacitors.
Q: Can I request custom dimensions if my frame has internal controller mounting?
A: Absolutely! If your controller (e.g., Sabvoton or Fardriver) is mounted inside the steel frame box, measure the remaining clear space and submit the dimensions via our Custom Battery Form.
