One board fits 12V/24V/48V RV systems. Minimizes B2B inventory costs and streamlines supply chain management.

3x Peak Inrush Tolerance: Integrated pre-charge circuit handles massive inverter surge currents without false tripping or shut-offs.

Dual-Layer SOC Algorithm: Combines Coulomb counting and dynamic voltage fusion for accurate, zero-jump SOC tracking under heavy loads.

Fully compatible with LFP, NCM/NCA, and LTO cells, giving clients the flexibility to switch cell suppliers based on dynamic global market prices

Anti-Intercellular Ringing: Advanced parallel management restricts cross-pack current surges during multi-battery banking setups.

Native Inverter Protocols: Plug-and-play CAN/RS485 communication compatible with industry leaders like , Pylontech, and Deye.

Plain-Text Diagnostics: Multilingual Bluetooth App displays explicit error alerts instead of confusing fault codes for easy troubleshooting.

Global Certified Safety: Hardware architecture engineered to pass strict UL1973, CE-EMC, FCC, and RoHS certification standards.

Heavy-Duty Thermal Design: Robust MOSFET layout supports true 300A continuous discharge under enclosed RV compartment environments.
