BSLBATT 8.8kWh 172Ah Stubby

The BSLBATT 8.8kWh 172Ah Stubby is a high‑capacity, rack‑mountable lithium battery designed for demanding energy storage applications. With a nominal energy of 8.908kWh and 170Ah capacity at 51.2V, it integrates a sophisticated internal Battery Management System (BMS) for safe, reliable operation.

The battery is built from 16 UL‑listed prismatic LiFePO₄ cells connected in a 16S2P configuration, delivering over 6000 deep discharge cycles at 80% depth of discharge (DoD). This means you can fully charge and discharge it daily for more than 15 years without significant degradation.

The BSL Battery Stubby 51.2V – 172Ah supports parallel connection of up to 63 units, allowing system expansion from a single 8.9kWh module to a massive 534kWh of stored energy, making it suitable for residential, commercial, and industrial backup or self‑consumption applications.

Product Benefits

With over 6000 deep discharge cycles at 80% DoD and a design life exceeding 15 years, the BSLBATT 8.8kWh 170Ah Stubby is built to last. Daily full cycling will not compromise performance, making it an ideal solar self‑consumption, time‑of‑use shifting, or off‑grid system.
Connect up to 63 units in parallel to scale your storage from 8.9kWh to 534kWh, accommodating growing energy needs without replacing existing hardware.
BSL Battery Stubby 51.2V – 172Ah built‑in BMS actively manages cell balancing, temperature, voltage, and current, protecting against overcharge, over‑discharge, short circuits (350A with 500µs delay), and thermal runaway.
Multiple communication ports (RS232, RS485, CAN, Wi‑Fi, Bluetooth) allow easy integration with most hybrid inverters and energy management systems.
The BSLBATT 8.8kWh 172Ah Stubby has a 10-year warranty

Additional Information

The 8.8kW BSL Battery Stubby 51.2V – 172Ah rack battery now includes wall-mount brackets as standard, helping reduce installation and mounting costs. For scalable storage, an optional stacking kit is available, supporting up to five batteries. This stacking solution offers a more cost-effective alternative to traditional server cabinets.
For optimal performance and safety, always follow the manufacturer’s installation guidelines. Use appropriate cabling and circuit protection rated for the maximum currents specified. The battery should be stored in a dry, cool environment (0–35°C) with ≤60% relative humidity when not in use.
