Modelo: B4850- Sku: DYNEBAT001
- Vendor: Dyness
Specifications
Product Description
The Dyness B4850 48V 2.4kWh LiFePO4 Lithium Battery is a low-voltage LFP storage module (48/51.2 V) designed for residential and small commercial systems seeking reliability, safety, and scalability. Its 19” rack format facilitates installation, while the integrated BMS with CAN/RS485 communication ensures intelligent charge/discharge management and native integration with leading 48 V inverters. With 2.4 kWh per unit and thousands of cycles, it allows for custom energy banks, expanding capacity as needs grow.
Main Features
- Stable and safe LiFePO₄ (LFP) chemistry with long service life.
- Capacity per module: 2.4 kWh · nominal voltage 51.2 V (LV 48 V system) · approx. 50 Ah.
- Integrated BMS with OVP/UVP, OCP, OTP/UTP protections and cell balancing.
- CAN/RS485 communications for SOC/SOH reading and control with Dyness profile.
- Low-profile 19” rack format for cabinet or wall installation.
- Scalable in parallel to increase kWh and available bank power.
Advantages or Benefits
- Safety and reliability: LFP chemistry and BMS protect against overvoltage, overcurrent, and temperature, minimizing risks and downtime.
- Simple integration: Dyness battery profiles available in leading 48 V inverters for quick and error-free commissioning.
- Modular scaling: add B4850 modules to increase autonomy and cover peaks without resizing the entire installation.
- Efficiency and performance: low internal resistance and stable current delivery, with less voltage drop and better energy utilization.
- Minimal maintenance: telemetry via communication bus and robust design for optimized total cost of ownership.
Purpose or Applications
Ideal for residential self-consumption with storage, backup/UPS systems depending on the inverter, small commercial installations, and 48 V telecom. The Dyness B4850 48V 2.4kWh LiFePO4 Lithium Battery is also perfect for expanding existing low-voltage banks, maintaining native communication between BMS and inverter.

Compatibilities
BMS compatibility with 48 V inverters offering Dyness profile via CAN/RS485: Deye SUN LP1/LP3 LV series, SolaX X1/X3 Hybrid LV, Solis RHI 48 V, Growatt SPH/SPA/SPF 48 V, GoodWe EM/ES 48 V, and Victron via GX device over CAN bus. Not compatible with high-voltage (HV) systems such as Tower/PowerCube/PowerDepot H or ecosystems requiring strings >150 V.
Installation recommendations: size cable cross-section to achieve ≤1–2 % voltage drop (25/35 mm² typical), protect each battery and the bank with DC fuse/MCB and accessible isolator, make power connections in star configuration on DC busbars, and use shielded data cable with shield grounded at one end only. Always select the “Dyness” profile in the inverter and verify SOC/voltage reading before commissioning.
In summary, the Dyness B4850 48V 2.4kWh LiFePO4 Lithium Battery is a professional and modular solution for demanding renewable energy projects: it increases autonomy, optimizes space, and improves the overall efficiency of your installation.
