• Extend Your Ride Time Without Compromising Performance：This dual battery parallel module lets you seamlessly combine two e-bike batteries into a single high-capacity power system—effectively doubling your range while maintaining full compatibility with your 750W or 1000W BBS/BBSHD mid-drive motor. Unlike simple Y-cables, it features intelligent voltage balancing circuitry that ensures both packs discharge evenly, preventing over-stress on one battery and maximizing total usable energy
• Safe, Balanced Charging Through a Single Port：Forget the hassle of unplugging and swapping chargers between batteries. The integrated shared charging port allows you to recharge both batteries simultaneously through one connection—saving time and reducing wear on connectors. The module’s internal balancing system ensures each pack receives the correct charge profile, enhancing battery health and longevity. Whether you use 48V or 52V systems
• Engineered for High-Power Demands and Harsh Conditions：Built with a solid aluminum housing, this module excels at dissipating heat generated during sustained 40A current draw—critical when climbing steep grades or accelerating with heavy loads. The -20°C to 60°C operating range makes it reliable in freezing winters or hot summer rides. High-quality internal components and a robust XT60H-M output plug (rated for 60A+) ensure stable power delivery without voltage drop, arcing, or overheating
• Universal Compatibility Across Popular E-Bike Platforms：Designed specifically for Bafang BBS, BBS02, and BBSHD mid-drive conversion kits, this module works flawlessly with most 24V–72V lithium battery packs using XT60 or compatible connectors. It’s also suitable for custom builds, cargo bikes, and DIY e-bike projects
• Protect Your Investment with Intelligent Power Management：Using mismatched or unbalanced dual batteries can lead to premature cell degradation or unexpected shutdowns. This parallel module solves that by actively balancing voltage and current flow between packs in real time—reducing strain and extending overall battery life. The aluminum casing shields sensitive electronics from moisture, dust, and road vibration, while the secure XT60H-M connection resists accidental disconnection
