Can it be used with a towing motor?

Yes, but you must confirm that the battery's maximum output current/power meets the motor's requirements. Running time can be calculated after selection is confirmed.

Will the battery discharge to the point where it cannot be charged?

No. The built-in BMS protection board will automatically prohibit load output if voltage is low. Timely charging will restore functionality.

How many batteries can be connected in series or parallel?

Maximum series connection is up to 51.2V (e.g., four 12.8V batteries). Maximum parallel connections should not exceed 4.

How to judge if the battery is fully charged without a status light?

The built-in BMS prohibits charging when full. Use a clamp ammeter to detect no charging current, indicating the battery is fully charged.

How long does it take to charge?

It depends on the charging current. Charging at 0.5C will fill the battery in about 2 hours.

Can the battery replace a lead-acid battery?

Yes, it can replace lead-acid battery packs up to 48V. However, you must confirm the battery's maximum output current/power meets system requirements.

Where can this battery be used?

Small capacity batteries suit UPS, emergency lights, electric toys, floor machines, and golf carts. Large capacity batteries suit RVs, camping, yachts, fishing boats, and solar energy systems.

How much protection can be achieved?

The general protection is IP55, with a maximum customizable option of IP68.

AI-Powered supplier vetting

SummaryThe supplier operates in rectifiers, inductors, distribution switchgear, energy-storage services, charging piles, battery parts, and related transmission equipment. It demonstrates documented quality-control, complaint-handling, and corrective-action procedures, ISO9001:2015 and ISO14001 certification, RoHS capability, 3D design, ODM/OEM, and broad customization services. It reports new-product activity within the past year and one national science and technology progress award. Production-related evidence includes laser welding and automatic wire cutting equipment, two quality inspectors, standardized finished-product inspection, inventory capability, and one-month lead times in both peak and off-season periods. However, it lacks a valid manufacturing-capacity contract with affiliated subcontractors, overseas warehouses, showrooms, agents, or branches, and has no available SDK. Financial records are identified by year but contain no performance values, so financial credibility cannot be assessed....

Supplier typeThe supplier’s stated business scope covers manufacturing and sales of rectifiers, inductors, distribution switchgear, battery parts, charging-related equipment, and transmission equipment, as well as energy-storage technology services and related research and development. This supports classification as a diversified manufacturer and technology/service provider in electrical and energy-storage equipment.

CertificationsThe supplier reports ISO9001:2015 and ISO14001 certifications, along with RoHS and other product or sustainability certification capabilities. These explicitly support recognized quality and environmental management credentials, although the specific scope and validity details of the additional certifications are not provided.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints, plus inventory capability and written supplier-service assessment procedures. However, it reports no overseas warehouse, showroom, agent, or branch, indicating that documented support exists but overseas physical service coverage is limited.

R&D capabilityThe supplier provides 3D software design, ODM, and broad R&D customization services, and reports having launched new products within the past year. One national science and technology progress award is also reported, although no SDK is available, which limits evidence of software-development integration.

Production capacityProduction evidence includes laser welding and automatic wire cutting equipment, two quality inspectors, standardized finished-product inspection instructions, inventory capability, and one-month average lead times in both peak and off-season. A stated lack of a valid manufacturing-capacity contract with affiliated subcontractors is a documented production-governance weakness, but the available evidence still confirms operational manufacturing capability.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, flexible customization, 3D software design, and ODM services. This is broad, direct evidence of capability across multiple customization routes.

Client casesThe supplier reports OEM service for well-known brands and participation in the INTERSOLAR EUROPE offline trade show, with overseas service offered in Italy. These indicate some brand-serving and market-exposure experience, but no customer names, project details, order history, or performance outcomes are provided.

Product Q&A

Q:What is the battery type?

We use lithium iron phosphate batteries, with no fire or explosion, wide operating temperature range, ensuring safety. Small-capacity batteries below 50Ah use cylindrical cells, while large-capacity batteries above 50Ah use square cells.

Q:Does the battery have BMS? What protection does it have?

The battery has a built-in BMS with overcharge, over discharge, over current, over temperature, under temperature, and short circuit protection. If protection triggers, the corresponding function is disabled, e.g., overcharge protection prohibits charging but allows discharge.

Q:What is the design life and cycle life?

Battery design life is 15 years, and cycle life can reach 6000 times.

Q:What charger should be used to charge the lithium battery?

It is recommended to use a lithium iron phosphate charger. We provide matching chargers: ECP series for low-power and ECA series for high-power applications.

Q:What is the recommended maximum charging current?

The recommended charging current for LDP series small-capacity batteries is 0.5C.
