FAQ
- Can This Battery Power a 12V Device?
- No. The 7.4V output is insufficient for 12V devices. Use a step-up converter or choose a higher-voltage battery pack.
- Is It Safe to Carry on Airplanes?
- Yes, if under 100Wh. This battery is 16.28Wh, complying with FAA carry-on rules. Declare it at security—do not check in.
- How Long Does a Full Charge Last in Storage?
- At 40% charge (3.8V/cell), it retains 80% capacity after 1 year. Stored fully charged, capacity drops to 65% in 12 months.
