7.2V 750mAh 14450 Battery Pack FAQs
What is the MOQ for the 7.2V 2S1P high-temperature battery pack?
The standard MOQ is 300–500 sets, depending on connector type and protection board configuration.
For early-stage testing or device matching, CMB provides engineering samples (≤200 pcs) to help customers validate performance in their devices.
Can this 2S1P pack directly replace two AA or NiMH batteries in series?
Yes. The 7.2V pack is designed as a drop-in replacement for dual-AA layouts with similar dimensions (14.5×102mm or 28.5×50.3mm).
We can adjust lead wires or terminal positions for direct compatibility with your battery compartment.
What is the main difference between the 3.6V and 7.2V 14450 configurations?
The 7.2V version uses two 14450 Li-ion cells in series (2S1P), delivering higher voltage for systems requiring 6–9V input.
It’s ideal for wireless transmitters, sensor modules, and control units that need extra power headroom or higher efficiency.
Can I request specific connectors or nickel tabs pre-installed?
Yes. We can add pre-soldered nickel tabs, Molex/JST connectors, or custom wire terminals according to your assembly process.
This helps shorten your integration and testing time.
What certifications and compliance documents are available for export projects?
CMB offers UN38.3, MSDS, RoHS, and IEC62133 certifications for this pack.
We also support custom documentation for transport or system safety audits upon request.
