Detailed technical reference guide for procurement officers and battery design engineers sourcing industrial BMS and storage equipment.
A 20S (20 Series) configuration outputs a nominal voltage of 72V. This is optimal for high-power micromobility platforms (like electric cargo scooters or golf carts) because higher system voltage decreases current demand for the same wattage output. This minimizes I²R resistance losses, reducing system heat dissipation requirements.
Lithium-ion cells experience rapid anode plating and permanent damage if charged at sub-zero temperatures. Our smart BMS protection boards feature integrated heating circuit controls. In freezing conditions, charging currents are routed first to embedded heating elements. Once cell temperatures reach a safe operating threshold (typically 5°C), the BMS switches current back to charging the pack.
Our LTWSmart Micro Inverters deliver 96.5% conversion efficiency. This minimizes energy lost as heat during the DC-to-AC conversion process. The IP67 rating ensures the micro-inverter can operate reliably outdoors under rain, snow, or high ambient humidity, making it suitable for balcony solar installations.
Developing a custom BMS from scratch requires extensive engineering time and tooling costs. Litongwei's shared boards utilize field-tested, pre-certified circuit designs. This allows you to scale production quickly with minimal tooling investment, while ensuring high performance, built-in patent protection, and full traceability.
Traditional portable power stations require a bulky external AC adapter. Bidirectional inverter technology consolidates the charging and discharging circuits into a single module. This lets you charge the power bank directly from a wall outlet using a standard AC cable, while also supporting high-speed reverse discharge to run AC appliances.
All safety control systems and power units undergo strict testing to meet target market regulations. Our manufacturing facilities are certified under IATF16949 and ISO9001/ISO14001. Products are fully compliant with UL, CE, FCC, RoHS, and UN38.3 standards, ensuring safe shipping and easy entry into global markets.
