FAQ for Covert & Spy Camera Batteries
A: We are constantly pushing the boundaries of miniaturization. We can produce cells with dimensions of just a few millimeters, but the final size is always a trade-off with capacity. Please contact us with your specific constraints.
A: We use a specialized lithium-ion chemistry with an extremely low self-discharge rate. This, combined with your device’s optimized deep-sleep mode, allows the battery to retain its charge for very long periods.
A: Due to the high degree of custom engineering and the specialized nature of this market, our MOQ for a new design typically starts at 20,000 to 50,000 units.
A: While there are some manufacturing and safety limitations, we can produce an incredible variety of free-form shapes. We excel at creating batteries that fit into the most unconventional spaces.
A: Yes, it is absolutely critical for safety. We use ultra-small PCM boards that provide all necessary protections (over-charge, over-discharge, short-circuit) in a minimal footprint.
A: Given the precision required, the lead time for the first batch of functional prototypes is generally 6-8 weeks after design finalization.
A: We take confidentiality extremely seriously. All projects begin with a mutual Non-Disclosure Agreement (NDA), and access to project details is strictly limited to essential personnel within our organization.
A: Yes. Even our smallest batteries are designed to handle the high, short bursts of power required for high-resolution recording and wireless data transmission.
A: They are typically charged via a discreet USB port on the host device. We design the battery and its PCM to be fully compatible with standard 5V USB charging.
A: After an NDA is in place, please provide a 3D model of the available space, the target standby and operational runtime, the power consumption profile of your electronics, and your estimated annual volume.
