Areas of Expertise
High-performance batteries demand meticulous thermal management to ensure uniform temperature distribution, peak performance, reliability, and long-term safety. Cell-level fusing enhances safety by mitigating the risks associated with internal short circuits or cell failures.
Marine applications present additional safety challenges due to water ingress and corrosive environments. By integrating an appropriate IP rating and fail-safe battery structure internally, you can trust in the battery’s reliability under normal conditions and ensure safe failure in case of saltwater ingress compromising the case.

Thermal Runaway can be controlled
Thermal runaway in a lithium-ion battery cell is a self-perpetuating process where the temperature rapidly rises, triggering exothermic reactions that intensify the heat. This cycle can lead to uncontrollable overheating, potentially causing catastrophic failures like fires, explosions, or the release of hazardous chemicals.
Careful battery design can prevent thermal runaway (triggered by a heating wire) from spreading from a single cell to the rest of the battery, as is demonstrated in this video.
Frequently asked questions
Q: What is your minimum order quantity?
A: For existing products, there’s no minimum order quantity (MOQ). However, for custom batteries, a small MOQ may apply, depending on the materials/parts involved. Our production process reduces tooling requirements, and we provide cost-effective options for pre-production sample parts like the case. This enables us to swiftly move from concept to pre-production parts at a very reasonable cost.
Q: What battery certification do you have/need for a new Battery?
A: We have extensive experience meeting certification requirements, covering CE-RED, CE-EMC, CE-ROHS, UL2271, IEC62133, IEC62619, MSDS, UN38.3, and air and sea safety certificates.
For new batteries, specific testing is essential. We can arrange the necessary 3rd party testing at competitive rates and guide you through this complex process.
Q: How long does it take to develop a new battery?
A: The timeline largely depends on the project and your specific requirements. Assuming we utilize 3D printing, CNC, and laser cutting for parts, a typical timeframe could range from 3 to 5 weeks. However, if tooling such as alloy extrusion is necessary, additional time may be needed.
Q: Do all rechargeable lithium batteries need circuit protection?
A: Indeed, all rechargeable lithium batteries typically necessitate circuit protection to facilitate safe charging/discharging operations, meet certification requirements, and ensure overall safety. This protection circuitry is vital for averting overcharging, over-discharging, and short circuits, which can trigger thermal runaway, fire, or explosion. Key functions of the protection circuitry encompass overcharge protection, over-discharge protection, short circuit protection, and temperature monitoring. These safety features play a crucial role in safeguarding both the battery and the device in which it is employed.
