With years of dedicated R&D in lithium battery protection systems, DALY serves customers in China and around the world, delivering tailored BMS solutions for application-specific operating conditions such as specialty vehicles, consumer EV batteries, and international energy storage rental.
Below is feedback from customers in China and abroad, offered as a reference for battery manufacturers and energy storage integrators selecting a BMS.
| Low-Speed EV Customer Golf Cart Project |
Golf carts start, stop, and brake frequently, causing noticeable swings in instantaneous load, so the vehicle demands tight current control and high safety protection standards.
The customer installs 200A M-series BMS boards in volume, paired with 16S 48V LiFePO4 battery packs. The pack integrates a cooling fan, a vehicle braking module, dual CAN/RS485 communication, and a heating module.
The braking module prevents wheel lock-up and cushions the instantaneous current surge when the brakes are applied, while the high-power pre-charge circuit supports heavy-load output on steep climbs. The complete communication chain connects directly to the vehicle controller, and the pre-assembled standardized modules streamline assembly on the factory production line.

| China-Based Lithium Battery Factory Two- and Three-Wheeler E-Mobility Battery Mass Production Line |
Two- and three-wheeler commuter batteries ship in very large volumes, so manufacturers prioritize compatibility, consistent quality, and ease of mass production.
The customer’s workshop uses H-series Hardware BMS boards on every line, with continuous current from 15A to 60A and compatibility with 3S–24S NMC and LiFePO4 cells.
The board dimensions fit standard battery compartments, and charge/discharge balancing stays stable under everyday commuting cycles. Pre-made wire harness modules cut down on manual soldering, performance stays consistent across large-volume shipments, and the boards reliably support routine mass-production delivery.

| U.S. Customer Solar Energy Storage + Battery Rental |
In residential solar storage and rental lithium battery equipment, long-term cycling of multi-cell series strings easily creates cell voltage imbalance, which directly shortens the service life of the entire storage system.
The customer chose an 8S–17S 100A active balancing BMS, paired with a matching interface board and a 4.3-inch touchscreen, with a built-in Bluetooth module. The 1A balancing current continuously corrects cell voltage differences, and the display shows SOC, voltage, temperature, and other key operating data at a glance. The communication protocols are compatible with mainstream inverters, so one product fits both home energy storage and shared rental equipment applications.

| U.S. Energy Storage Customer Long-Life Storage with an Early-Generation BMS |
A U.S. energy storage contractor chose DALY’s first-generation high-current BMS early on, and the complete solar storage system, connected to inverters, was put into service. The equipment has now run reliably for more than 5 years with no widespread failures.
Efficient thermal design and multi-layer protection handle the around-the-clock charge and discharge duty of energy storage. Years of reliable field operation are why the customer keeps reordering DALY products for new projects.
