FAQ for Portable Wi-Fi Hotspot Batteries
A: We use a combination of our highest energy density cells to create a very high-capacity pack (e.g., 5,000mAh to 10,000mAh), which, when paired with your device’s efficient power management, can achieve all-day or even multi-day use.
A: We design our battery packs with low internal resistance (IR) cells to minimize heat generation from the battery itself. We also work with your engineering team to ensure the pack’s placement and housing contribute to the device’s overall thermal dissipation strategy.
A: For a new custom design, our MOQ typically starts at 20,000 to 50,000 units.
A: Yes, many MiFi devices feature a user-replaceable battery. We specialize in designing these packs with a durable enclosure and reliable contacts for easy swapping.
A: Our MiFi batteries are designed for a long service life, typically specified to retain high capacity after 500+ charge cycles.
A: After the design is finalized, the lead time for the first batch of functional prototypes is generally 5-7 weeks.
A: Yes, we can design the smart BMS to include a power bank function with a USB output port, adding significant value for the end-user.
A: Very accurate. We integrate an intelligent BMS with a coulomb-counting fuel gauge that provides precise, real-time State of Charge (SoC) information to the device’s operating system.
A: Absolutely. All our batteries are rigorously tested to meet UN38.3 standards for safe transportation, and we design them to be compliant with airline carry-on regulations (typically under 100Wh).
A: Please provide your device’s voltage, required runtime (hours), the continuous and peak power draw (Watts) of the modem and electronics, dimensional constraints, and your estimated annual volume.
