⚡ EM3ev Rhino 3P — 52V 15Ah (756Wh) – 14S3P
High-Safety Design | CNC Aluminium Case | Cell-Level Fusing | Next-Gen Rhino Rectangle Series
The Rhino 3P Ebike Battery is EM3ev’s most advanced 52V battery system, built with 42pcs genuine 21700 cells, a high-current Smart BMS, and fully fused cell architecture. Designed with a CNC-machined aluminium case and fire-resistant internal foam, it delivers automotive-grade structural safety, long service life and exceptional reliability for 52V ebike and high-power applications.
🦏 Rhino-Series Structural Safety & Design Innovations
- 🔥 Full cell-level fusing — each cell is individually protected, preventing thermal events caused by internal shorts.
- 🛡️ Fire-resistant structural foam — suppresses thermal propagation and stabilizes the pack, similar to EV-module construction.
- 📏 Custom PCB interconnect — improves internal routing, reduces mechanical stress and avoids failure points found in mass-produced packs.
- 🏗️ CNC-welded precise terminations — consistent weld quality, improved durability and long-term reliability.
🏗️ CNC Aluminium Case & Reinforced Construction
- Custom-designed aluminium enclosure, anodised for corrosion resistance.
- In-house CNC cell holder for tight, safe and vibration-resistant spacing.
- Rigid module-like construction that feels extremely solid and long-lasting.
🧠 Smart BMS with Diagnostic Logging
- 30A+ continuous discharge capability (limited by 50E cells in 3P format), 50A (1s) peak trip.
- Separate charge/discharge circuits with 3-wire BMS architecture.
- Balancing starts at >50% SOC — no need for 100% charging for maintenance.
- Pre-charge / no-spark function included for safer controller connection.
- Compatible with parallel-balancing module (10S–14S dual-battery systems).
🔌 Connection & Charging Options
- Available connectors: XT90-S, XT60, Anderson Powerpole, 4mm bullet connectors.
- High-current charge port rated for ~8A (highly reliable under load).
- Optional chargers: 58.8V 2A fanless, 4A, 5A or 6A fast chargers.
