The APTPES 18.5V 3200mAh (0.2C discharge) lithium battery pack delivers reliable power for portable measuring instruments. Built with lithium-ion cells in a 5 series 1 parallel (5S1P) configuration, this pack integrates a multi-protection circuit board and pre-fitted terminal wires for immediate deployment. Manufactured under strict QC protocols with CE, RoHS, and UN38.3 certifications, it serves distributors and OEMs seeking dependable energy solutions. Contact us today for bulk pricing and customization options.
Integrated Multi-Protection Circuit: The built-in protection IC monitors 18.5V cell voltage in real time, guarding against overcharge, over-discharge, overcurrent, and short circuits. This prevents catastrophic cell failure during abnormal operating conditions.
Precision Cell Matching: Each lithium-ion cell undergoes capacity grading and internal resistance sorting before assembly into the 5 series 1 parallel (5S1P) configuration. This matching process ensures uniform charge and discharge across all cells, extending pack lifespan and maintaining voltage stability.
Factory-Tested Quality Assurance: Every battery pack completes a full electrical testing cycle at our Dongguan facility, including charge retention verification, protection board trigger validation, and dimensional inspection. Test reports accompany each batch shipment for OEM traceability.
Global Certification Compliance: Manufactured to meet CE, RoHS, UN38.3, and MSDS documentation requirements. These certifications enable duty-free import into EU markets and compliant air freight for international distribution channels.
Compact Energy Density: The lithium-ion cell platform delivers high energy density relative to pack volume at Approx. 250g (For reference only, subject to actual product), making it suitable for portable and embedded applications.
Plug-and-Play Terminal Integration: Factory-assembled with terminal wires and connectors, ready for direct integration into device PCBs without additional soldering or wire preparation.
Extended Cycle Life: The lithium-ion cells exhibit no memory effect and maintain over 80% capacity retention after 500 full charge-discharge cycles. Low self-discharge characteristics (under 3% per month) support long-term storage without significant capacity loss.

This 18.5V 3200mAh (0.2C discharge) battery pack is engineered for portable measuring instruments and related applications. Equipment manufacturers in the field testing tools sector integrate this pack as a primary power source for portable and stationary devices. The stable voltage platform and protection circuitry make it suitable for handheld analyzers where reliability is non-negotiable. OEM customers in consumer electronics, medical devices, and industrial instrumentation have validated this pack for volume production.
A: Use a dedicated lithium-ion charger with 21.0V MAX (Must use the matching charger) output in CC/CV (constant current/constant voltage) mode. Standard AC/DC adapters without CC/CV regulation will damage the protection IC and risk thermal runaway.
A: The integrated protection IC continuously monitors cell voltage and current flow. It disconnects the circuit when voltage drops below the safe threshold (over-discharge protection) or exceeds the charge limit (overcharge protection). The board also triggers on overcurrent events to prevent cell damage from short circuits.
A: Direct parallel connection of finished battery packs is not recommended. Even identical models from the same batch may have slight voltage and internal resistance differences that cause circulating currents. For applications requiring higher capacity, contact our engineering team to order factory-balanced multi-parallel packs with matched cells.
A: The stated dimensions refer to the battery cell body. Wire terminals extend an additional 20-80mm beyond the cell dimensions. Reserve space for wire routing in your device housing design.
A: The maximum continuous discharge current is Please refer to the specific cell datasheet (usual. Verify your device's steady-state current draw and startup surge requirements against these ratings. If your application needs higher current, we can customize the cell selection and protection board parameters.
