503035 3.7V 500mAh LiPo Battery

Overview

This listing consolidates 10 LiPo battery models across three width families — the 5mm-thick 503 series (500–600mAh) and the 6mm-thick 601/602 series (100–300mAh) — under a single OEM-ready supplier. Whether you’re sourcing a high-capacity cell for a Bluetooth speaker or a compact slim cell for a GPS tracker, all models ship with PCM protection, meet UN38.3 transport certification, and support full dimensional and connector customization. One RFQ. One factory. Ten models.

✅ Why Source All 10 Models From One Supplier

1. Consolidated Procurement — One PO, Ten SKUs Managing multiple battery suppliers for a multi-product line creates friction: different lead times, inconsistent PCM specs, mismatched wire gauges, and fragmented quality control. Sourcing all 10 models from a single factory eliminates these pain points and simplifies incoming inspection.

2. Cross-Model PCM Consistency Every model — from the 601220’s 100mAh to the 503040’s 600mAh — uses the same PCM protection logic and passes identical QC checkpoints. Your engineering team documents one protection profile, not ten.

3. Flexible MOQ Per Model Mixed orders accepted. Run high volume on your best-seller (e.g., 503035 × 5,000 pcs) while sampling adjacent models (e.g., 601530 × 100 pcs) within the same purchase order.

4. Fast Dimensional Substitution If your device cavity changes between hardware revisions, we can match your new dimensions without changing suppliers. Our tooling library covers hundreds of form factors within all three width families represented in this listing.

5. UN38.3 Certified — Air-Freight Ready All models are certified to UN38.3, enabling reliable international air shipping without customs holdups — critical for time-sensitive product launches.
