Optimized Title: 60V 25A PCB Protection Board for Lithium-ion Battery Pack with Balance and NTC

Bisida's battery management system (BMS) offers a comprehensive range of protective features and reliable performance. The product dimensions are 64mm55mm8mm, with a voltage rating of 60V and a charger voltage of 67.2V. The working current is 25A, while the recommended charging current is below 10A. The BMS operates within a temperature range of -20°C to 70°C, and it is designed for use with 3.7V lithium-ion batteries (single cell).

One of the key features of this BMS is its instantaneous current capability, which can reach 3 to 5 times the working current. This ensures robust protection against sudden surges or spikes in the electrical system.

The package contents include a battery protection board and a cable. If you have specific requirements, you may need to request a custom or batch order. In such cases, please communicate with the seller to confirm the details.

It is important to note that this product uses an integrated IC solution, which ensures a high level of SOC (state of charge) accuracy. The BMS monitors the voltage of each string, and it is essential that the voltage, internal resistance, and capacity of the assembled batteries are uniform. Otherwise, the BMS will trigger its disconnection protection function.

This BMS is an industrial semi-finished product, and it requires professional electrical knowledge for installation and assembly. Users are advised to understand this requirement before proceeding with the product.

Bisida's BMS offers a comprehensive range of protection functions, including overcharge protection, overdischarge protection, overcurrent protection, short-circuit protection, temperature protection, and voltage balance (passive balance). These features ensure the safety and longevity of the battery pack.

The BMS supports charging and discharging of (3.7V) lithium-ion batteries within the voltage range of 2.65V to 4.25V. The low-temperature protection extends down to -20°C, while the high-temperature protection reaches up to 70°C. However, it is important to note that different voltage and current parameters may have specific details, and users are advised to confirm the accurate data with the seller.

Before installing the BMS protection board, it is crucial to ensure that the voltage, capacity, and internal resistance of the battery pack are properly matched. The voltage difference between the battery sections should not exceed 0.05V, the internal resistance difference should be less than 5mΩ, and the capacity difference should be less than 30mAh. Failure to meet these requirements may result in the battery pack being unable to charge.

The wiring method for the BMS involves connecting the B- terminal to the battery pack's negative, and the C- terminal to the charging negative/output negative. All the positive electrodes are connected to the total positive pole from the battery pack.

Bisida's BMS utilizes high-quality (A-level) protective integrated circuit ICs, sourced from industry-standard solutions. The BMS is manufactured using top-quality MOS and IC components. The company also offers OEM/ODM customization services, catering to specific customer needs. Users with unique requirements are encouraged to contact the customer service team for further assistance.
