Custom OEM Battery Charger Module Supplier & Exporters in the Puebla Market

For standard catalog charger modules, typical production lead times range between 10 to 15 working days. Custom OEM/ODM runs (such as custom wiring harnesses, modified CC/CV profiles, or conformal moisture potting) average 3 to 4 weeks. Most ocean freight is routed from Ningbo or Shanghai port directly to the Port of Veracruz (closest Atlantic gate, ~2.5 hours by highway to Puebla) or the Port of Manzanillo on the Pacific coast, followed by bonded overland transit. Air shipments via Mexico City (AICM/AIFA) or Puebla International Airport (PBC) can be delivered within 5 to 7 business days for urgent prototype runs.

Our products are built in strict accordance with international IEC/EN 62368-1, CE LVD, CE EMC, and RoHS directives, utilizing UL-certified PCB base substrates and safety-critical components (optocouplers, primary capacitors, and transformers). For Mexican industrial end-users requiring NOM-001-SCFI or NOM-019-SCFI conformity, we supply comprehensive laboratory CB test reports, schematics, component manifests, and isolation test documentation to streamline verification by authorized Mexican verification bodies (UVAs) or testing laboratories (NYCE/ANCE).

Yes. Standard industrial power supplies feature fixed constant-voltage rails that trip into overload protection when connected directly to deeply depleted battery banks. Harlon’s custom OEM charging modules are engineered with tailored constant-current (CC), constant-voltage (CV), and float charging state-machine logic. Whether you are charging 24V/48V Lithium Iron Phosphate (LiFePO4) AGV packs, high-discharge Lithium Titanate (LTO), or conventional sealed lead-acid (SLA) forklift banks, our engineers can calibrate the current limit threshold, thermal foldback, and automatic restart hysteresis to protect battery cell integrity.

Operating at high altitudes requires both electrical clearance compensation and thermal derating. Due to lower air density in the Puebla-Tlaxcala basin, standard convection cooling efficiency drops by approximately 10% to 15% per 1,000 meters above 1,000m. To guarantee uncompromised 24/7 industrial duty, we engineer custom models intended for Puebla with larger aluminum heat sinks, 105°C ultra-low ESR electrolytic capacitors, higher thermal conductivity silicon pads, and optional active ball-bearing cooling fans with smart RPM sensing. Furthermore, internal clearance and creepage distances are widened to maintain insulation integrity up to 3,000 meters elevation.

We support prototype and functional validation testing. For standard models such as the S-120, S-200, or S-1500 series, sample quantities (1 to 5 units) can be dispatched quickly for benchtop evaluation. For customized OEM designs involving custom chassis sheet metal, connector terminations, or bespoke charging firmware, sample qualification batches are furnished prior to commercial volume runs. Regular production MOQs generally start at 50 to 100 units depending on customization complexity, backed by volume tier pricing.

We offer flexible commercial arrangements including FOB China ports (Ningbo/Shanghai/Shenzhen), CFR/CIF Veracruz/Manzanillo, and EXW factory terms. For established manufacturing clients and verified corporate accounts, we accept wire transfers (T/T), confirmed documentary Letters of Credit (L/C at sight), and structured progress payments. Quotations can be executed in USD, EUR, or CNY to optimize treasury efficiency.
