Smart Battery Management System (BMS) accessories engineered for lithium battery packs — standard, smart, and active-balancer configurations from 4S to 32S. As a factory-direct BMS manufacturer and supplier in Shenzhen, we ship CE and UN38.3 certified units to importers, distributors, and pack assemblers in 25+ countries.
As a dedicated lithium battery BMS manufacturer, we build standard, smart, and active-balancer BMS accessories to match your pack size, chemistry, and communication requirements.
Need a specific cell count, current rating, protocol or enclosure? Our engineers design and build to your exact pack specification.
Every lithium battery BMS we manufacture is tested for safety, accuracy and long-term reliability before it ships from Shenzhen.
Automatically cuts charging or discharge current when cells reach their safe voltage limits, protecting cell chemistry and lifespan.
Choose passive balancing for cost efficiency or active balancing for maximum usable capacity — both available across our BMS range.
Continuous temperature sensing with automatic load reduction or shutdown when thermal limits are approached.
Industry-standard communication protocols for seamless integration with hybrid inverters, EMS platforms and monitoring apps.
Flexible cell-series support for everything from small power tool packs to large-format ESS battery banks.
Smart BMS models track state-of-charge and state-of-health, giving you accurate capacity and degradation data over time.
Every BMS accessory meets CE and UN38.3 transport-safety standards required for confident global import.
Manufactured in-house at our Shenzhen facility — no distributor markup, with pricing that scales from samples to bulk orders.

From home solar storage to industrial ESS banks, our BMS accessories protect and optimize lithium packs across every application.
Residential solar storage packs
Industrial & C&I battery banks
Electric vehicle & light EV battery packs
High-discharge cordless tool packs
Off-grid & hybrid inverter systems
Marine and recreational vehicle packs
We design and manufacture our BMS accessories at our own Shenzhen facility — not a resold third-party board — so we control quality end to end.
Every BMS unit is tested for balancing accuracy, protection thresholds and communication before it ships.
Sample orders welcome for evaluation, with tiered pricing as your order quantity scales into production runs.
Standard and smart BMS models typically ship within 7–15 business days from our Longgang factory.
Our team helps confirm inverter/EMS compatibility and communication protocol before you commit to an order.
4S–32S configurations, active & passive balancing, and CE/UN38.3 certification — factory-direct from Shenzhen.
