New Launch: XJ-D647 6S–24S 100A Compact High-Current BMS | Dual NTC & Passive Balance Design

We are thrilled to officially launch our brand-new high-performance hardware Bms —XJ-D647. Designed to solve the industry pain points of bulky size, insufficient heat dissipation, unstable protection, and high cost for high-string and high-current battery packs, this new model supports ultra-wide string coverage from 6S to 24S with a maximum continuous working current of 100A. It integrates comprehensive protection functions, dual temperature monitoring, passive cell balancing, and a weak current switch, delivering a compact, stable, and cost-effective battery management solution for power equipment and grid-off energy storage systems.

Full Core Features of XJ-D647 BMS

The XJ-D647 is built with industrial-grade hardware configuration, covering all essential safety and functional requirements for mid-to-high power lithium battery systems:

• Ultra-wide compatibility: Supports 6S–24S lithium battery packs, compatible with NMC, LiFePO4 and other mainstream lithium battery chemistries
• High current output: Stable 100A continuous working current, fully meeting long-term high-load operation demands
• Built-in passive balancing: Equipped with passive cell balancing function to automatically calibrate cell voltage differences, improve battery pack consistency, maximize battery capacity utilization, and extend overall cycle life
• Dual NTC temperature monitoring: Adopts exclusive dual-temperature sensing design, including one built-in MOS NTC and one external hanging NTC. It monitors both board temperature and internal battery pack temperature in real time, achieving all-round over-temperature protection and effectively avoiding thermal runaway risks under high-current continuous discharge
• Weak current switch & matched wiring harness: Comes with a reserved weak current switch for convenient power control and standby power cut-off, paired with dedicated wiring harness for plug-and-play easy installation
• Complete safety protection: Integrates industry-standard full protection mechanisms including over-charge, over-discharge, over-current, over-voltage, and short-circuit protection, ensuring zero-risk operation of battery packs under complex working conditions

Industry Leading Advantage: High Current & High String with Super Mini Size

The biggest highlight of XJ-D647 is breaking the industry’s conventional design limitations. Traditionally, 6S–24S high-string and 50A–100A high-current BMS requires large-size PCBs to ensure heat dissipation and stability, resulting in bulky installation and poor compatibility with irregular battery packs.

With our optimized circuit layout and high-efficiency heat dissipation solution, XJ-D647 achieves ultra-small size of 110*65*10mm while supporting 24S maximum string and 100A high current. The compact structure occupies extremely limited internal space, perfectly adapting to various square, irregular, and compact battery pack designs. It solves the installation difficulties of high-power BMS for narrow-space equipment and greatly improves product compatibility and assembly flexibility.

6S–24S 50A–100A Detailed Application Scenarios

Covering 6S to 24S full strings and 50A to 100A wide current range, XJ-D647 serves diversified mid-to-high power scenarios across mobility, tools, and energy storage fields. The segmented application matching is as follows:

• 6S 100A (22.2V): Suitable for high-power handheld power tools, large portable vacuum cleaners, outdoor portable lighting equipment, and medium-sized intelligent robotic equipment, supporting long-term high-load motor operation
• 7S–8S 100A (25.9V–29.6V): Ideal for heavy-duty garden equipment including high-power lawn mowers, leaf blowers, and electric pruning machines, adapting to outdoor high-intensity intermittent work
• 9S–12S 100A (33.3V–44.4V): Perfect for light electric tricycles, medium-speed electric scooters, and small sightseeing shuttle cars, meeting daily commuting and short-distance transport power demands
• 13S–14S 100A (48V–52V): Matches 48V/52V high-power electric two-wheelers, golf carts, and low-speed engineering vehicles, supporting stable climbing and heavy-load driving
• 15S–16S 100A (55.5V–60V): Widely used in 60V high-speed electric motorcycles, modified mobility equipment, and medium-capacity portable energy storage power stations
• 17S–20S 100A (63V–74V): Suitable for 72V heavy-duty electric vehicles, household solar off-grid energy storage systems, and small industrial backup power supplies
• 21S–24S 100A (77.7V–88.8V): Applied to high-power commercial energy storage equipment, inverter ESS systems, base station standby power, and large sightseeing vehicles, fully meeting long-term high-current continuous discharge requirements
• 50A–80A Medium Current: Applicable to all above scenarios with medium-load and low-frequency start-stop working conditions, achieving higher cost performance

Core Competitive Advantages of XJ-D647

Compared with peer products in the market, XJ-D647 has absolute comprehensive advantages in solution design, performance and pricing:

Optimized professional hardware solution: We adopt self-developed circuit layout and component matching technology, realizing the perfect combination of large current, high string and mini size. The hardware solution is more mature and stable, with lower heat generation and stronger overload resistance during long-term operation.

Superior stability & longer service life: Different from complicated Smart Bms with high failure rate, XJ-D647 is a high-quality hardware BMS. It avoids system crash and communication failure risks, features ultra-high operational stability, stronger environmental adaptability, and longer overall service life, fully meeting long-term industrial continuous operation standards.

Industry-leading cost performance: Our biggest highlight lies in the 16S/24S 100A high-spec model. For such high-string and high-current specifications, peer products are usually expensive and bulky, while XJ-D647 achieves more stable hardware performance at a more competitive price, completely outperforming mainstream market products in cost performance.

Final Summary

XJ-D647 is a disruptive compact high-current hardware BMS launched by XJBMS, integrating dual NTC temperature monitoring, passive balancing, full safety protection, and weak current control. With 6S–24S ultra-wide string compatibility, 100A max continuous current, and ultra-small body size, it solves the installation and performance pain points of traditional high-power BMS. Especially for 16S and 24S 100A high-spec applications, it provides customers with stable, durable and cost-effective hardware solutions that far surpass peer products.
