787A+ Battery Spot Welder and Charger

The 787A+ Battery Spot Welder and Charger is a dual-function benchtop unit designed for joining nickel-plated steel or pure nickel strips to lithium-ion and lithium-polymer battery cells via resistance spot welding. Supplied by Mei Li De Electronic Co., Ltd. from Foshan, Guangdong Province, the machine integrates a welding power source with a cell-charging circuit, allowing operators to alternate between pack assembly and cell maintenance without relocating cells to a separate charger. The welding mode delivers pulsed DC current through a hand-held electrode assembly, with the source noting adjustable parameters to accommodate varying strip thicknesses and cell terminal geometries.

Construction centres on a transformer-based welding topology with silicon-controlled rectifier (SCR) or IGBT switching, typical for entry-to-mid-level spot welders in the 787-series family. The integrated charger function supports lithium chemistry cells, though the source does not specify supported voltages (typical 3.7V nominal per cell, 4.2V charge termination) or charge-rate capability in amperes. Electrode material is commonly copper-chromium or copper-tungsten alloy in this class, with tip diameters of 3-6mm standard for 0.1-0.3mm nickel strip. The compact chassis dimensions implied by the description suit small-workshop or prototype-lab deployment rather than high-volume automated lines.

Primary buyers include custom battery-pack manufacturers, e-bike conversion workshops, portable-power-system builders, and research labs prototyping energy-storage modules. The dual-function design reduces capital equipment count for low-to-medium volume operations. Mei Li De Electronic lists no stated MOQ, so buyers should confirm unit-pricing breaks and whether volume-tier discounts apply for 10, 50, or 100-unit purchases. The Foshan location offers proximity to Shenzhen and Hong Kong logistics corridors, with typical export routing through Yantian or Shekou port under FOB or CIF terms to be confirmed directly with the supplier.

Mei Li De Electronic Co., Ltd. is located on Guda Road, Zhangcha, Foshan, Guangdong Province, China (postal code 528000). The company holds a Harbor trust tier on the platform, with a response rate of 0.00 percent and no recorded average response hours. This lack of engagement metrics means buyers cannot rely on platform-mediated communication alone and should establish direct email or telephone contact early in the sourcing process. The Foshan address places the supplier in the Pearl River Delta manufacturing belt, with established electronics component and tooling supply chains, though this regional concentration does not independently confirm in-house design or assembly capability.

The supplier's product focus centres on battery welding and charging equipment, with this 787A+ unit representing a combined-function offering for small-scale battery pack producers. No ISO certification details, factory audit reports, or R&D staff numbers appear in the source data. Buyers should request current quality-management certificates, production-capacity figures, and whether the 787A+ is manufactured under OEM/ODM arrangement or is a proprietary Mei Li De design. The absence of stated MOQ suggests flexibility, but buyers should confirm this during direct negotiation and ask for sample-unit availability with explicit warranty terms before committing to volume orders.
