What are our solutions and why choose our medical batteries?
Tailored Power Solutions for Life-Saving Medical Devices
We specialize in custom battery packs for critical medical equipment such as defibrillators, patient monitors, and portable diagnostic systems. Our solutions are engineered to meet the specific electrical, dimensional, and regulatory requirements of each device, working closely with medical OEMs to ensure seamless integration and optimal performance.
Unmatched Safety and Compliance with Global Medical Standards
Battery safety and transport documentation must be selected for the exact model, application and destination market. Our team can review applicable requirements and available reports with the OEM. Quality-system certificates and battery test reports do not replace complete-device medical safety assessment or automatically establish CE conformity.
Reliable Performance in Critical and Low-Temperature Environments
Operating and storage limits depend on the selected cell, pack construction and validated device conditions. Define charging and discharging temperatures separately, then verify runtime, protection and recovery at the required environmental limits. Low-temperature charging may require charge inhibition or controlled heating; it is not an inherent capability of every medical battery pack.
Battery Packs for Medical Devices
Large Power designs custom lithium battery packs for medical devices, including patient monitors, portable ultrasound systems, oxygen concentrators, infusion pumps, and surgical instruments. We size each pack around the device’s voltage range, peak current, and runtime target, then define enclosure and battery management requirements with the OEM.
Customer Pain Points:
Runtime vs. Weight Dilemma – Clinicians require devices light enough for all-day use but with enough battery life for multiple uninterrupted scans. This creates a difficult trade-off between a heavier, long-lasting battery and a lighter option that triggers “range anxiety.”
Inconsistent Performance – Sudden battery failure during critical procedures is unacceptable. Poor cell quality can cause unexpected shutdowns, inaccurate battery readings, and a loss of clinician trust.
Safety & Reliability Risks – In close proximity to patients, the battery must meet the highest safety standards. Poor thermal management can cause overheating, and inadequate protection circuits can damage both the battery and the device.
Solutions:
The 14.4 V 6200 mAh battery pack is a reference platform for portable ultrasound integration. Final suitability depends on the approved pack specification and complete-device validation.
Review cell traceability, BMS configuration, charger compatibility and the applicable test-document scope with the engineering team. Battery-level evidence supports, but does not replace, medical-device safety and essential-performance assessment.

Portable oxygen concentrators in home and ambulatory care
Portable oxygen concentrators use battery power to support prescribed oxygen therapy away from mains power. Delivery modes and settings vary by device: pulse-dose settings are not equivalent to continuous-flow rates.
Validate runtime at the specified operating settings, with the actual compressor duty, accessories and environmental conditions. Define low-battery indication, shutdown behavior and the required response to power loss at device level.
Battery Cell Architecture
- Choose the cell model and series/parallel count from the host voltage window, compressor current and required runtime.
- For the listed 14.4 V 6700 mAh reference pack, verify the released specification and test data rather than inferring cell model or capacity from the configuration alone.
BMS and Host Integration

- Validate SOC reporting and low-battery warnings across the intended load, temperature and aging conditions.
Mechanical Verification
- Confirm finished dimensions, connector keying, polarity, retention and replacement handling.
- Assess shock, vibration and cleaning requirements for the actual device environment.
- Review battery documents for the exact model and market; complete-device compliance is assessed separately.
