FAQ for Handheld GPS & Satellite Messengers Batteries
A: We use a zero-compromise approach: utilizing only premium, Tier-1 grade cells, implementing a Failure Mode and Effects Analysis (FMEA) in the design process, and conducting 100% end-of-line functional testing on every battery pack.
A: At freezing temperatures (0°C / 32°F), a standard LiPo might only deliver 70-80% of its capacity. Our wide-temperature formulation is designed to deliver over 90-95% of its capacity under the same conditions, and still perform reliably at much lower temperatures.
A: For a new custom design, our MOQ typically starts at 20,000 to 50,000 units, depending on the complexity of the housing and electronics.
A: Yes. We can design the battery pack with a fully sealed, robust housing and waterproof contacts to be a key component in your IP67-rated instrument, ensuring it works even after being submerged.
A: Extremely accurate. Our intelligent BMS uses coulomb-counting and communicates with the device’s processor to provide a precise, real-time State of Charge (SoC), which is critical for planning in the backcountry.
A: Given the complexity of the custom housing and wide-temperature validation, the lead time for the first batch of functional prototypes is typically 7-9 weeks.
A: Our batteries are designed with very low self-discharge rates. They can be stored for a year and still retain a very high percentage of their charge, ensuring the device is ready for an unplanned adventure or emergency.
A: Yes, we specialize in designing user-replaceable battery packs with robust, glove-friendly latching mechanisms and durable connectors for easy swapping of spares on long trips.
A: Yes. All our batteries are tested to UN38.3 standards for safe transport and are typically designed to be under the 100Wh airline carry-on limit, making them ready for global expeditions.
A: Please provide your device’s voltage, required runtime (in hours or days), power consumption profile (standby, tracking, transmitting), dimensional constraints, any specific IP or durability requirements, and your estimated annual volume.
