Bespoke Leisure systems and Lithium batteries

Bespoke Lithium Batteries

At Ultimate Audio, based in Bromsgrove, West Midlands, we offer a professional bespoke battery building service using advanced LiFePO₄ (Lithium Iron Phosphate) battery technology, suitable for a wide range of vehicle, audio, and leisure applications.

Whether we are building a high-performance car audio battery engineered for maximum SPL and rock-solid voltage stability, or a custom LiFePO₄ battery system for motorhomes and camper vans requiring large reserve capacity for extended off-grid use, every solution is carefully tailored to the exact requirements of the customer and application.

All batteries are designed and built in-house at our Bromsgrove workshop. This allows us to precisely select the optimal cell configuration, capacity, discharge rate, and protection systems to ensure reliable, application-specific performance. LiFePO₄ chemistry offers significant advantages over traditional lead-acid batteries, including enhanced safety, longer service life, reduced weight, and superior electrical performance, resulting in a dependable power solution perfectly matched to your vehicle, audio system, or leisure setup.

Each battery system is coupled with a dedicated Battery Management System (BMS) to ensure safe operation and long-term reliability. The BMS provides under-voltage and over-voltage protection, over-current protection, comprehensive temperature monitoring, and precise cell balancing across the entire battery bank.

Battery banks are available in a wide range of voltages and configurations, allowing us to deliver a fully customised solution to suit the specific demands of each application.

Battery along with suitable BMS prices start from £795
