FAQs: AS802030 3.7V 420mAh Li-Po Battery
Q: What are the exact dimensions and key specifications of the AS802030 battery?
A: The battery measures approximately 8.0mm in thickness, 20mm in width, and 30mm in length ($\pm0.5\text{mm}$ tolerance). It has a nominal voltage of 3.7V and a capacity of 420mAh, providing a compact and lightweight energy solution.
Q: What safety certifications does this battery hold for global compliance?
A: It complies with international safety standards, including UL (UL1642 / UL2054), CE, RoHS, and REACH, along with UN38.3 and MSDS reports for air and sea transport.
Q: Can the wires, connectors, and protection circuitry (PCM/BMS) be customized?
A: Yes, full customization is available. You can request specific lead wire lengths, wire gauges (e.g., UL1007 AWG26/28), connectors (JST, Molex, Hirose, etc.), and custom PCM/BMS designs featuring overcharge, over-discharge, overcurrent, and short-circuit protection (NTC temperature sensors can also be included).
Q: Is this cell suitable for multi-cell battery pack configurations (Series/Parallel)?
A: Yes, cells can be configured into multi-series or multi-parallel battery packs (such as 1S2P, 2S1P) with customized BMS management according to your device’s voltage and runtime demands.
Q: What are the primary applications for the AS802030 battery?
A: It is ideal for space-constrained portable and wearable electronics, including:
Smart Wearables & Consumer Electronics: Bluetooth headsets, smartwatches, fitness trackers, and wireless audio devices.
