Hi team. Just reporting my 3rd success, having now gotten through Los Angeles, Barcelona, and London Gatwick with my 10s4p. I should note that its in a 10x4 block mountainboard esque box that is completely separate from my board. Leaving LAX they asked me to explain what it was and I explained there are 40x 3.7v 1000mah (wink) lithium ion cells with 10 cells in series, 4 in parallel for a nominal capacity of 148wh.
Looks like using 3.7v 1ah, you can fit a max of 43 cells, but theres no practical use for a block that size. 6s7p is the largest battery that makes sense for this purpose which is “155.4wh” or 388.5wh if youre using 2500mah cells.
Hopefully this eases some worried minds. Keep in mind that my battery is in a 10x4 block and as always, YMMV.
it definitely looks like a bomb! the only reasoning I can come up with is that it looks like a wheelchair battery and not like an electric skateboard battery, which, to someone not in the know, is associated with hoverboards and the bans surrounding them.
148 Wh is under the IATA accepted capacity of 160 Wh for a single battery. Not sure the purpose of the battery is any relevant.
You see a lot of details in the X-rays machine…
Ah! right!..you “forgot” to mention that minor point
I was surprised with the relatively small size of the battery.
Not sure they can actually control that if they do not have access to the writing on the battery
honestly nobody even asked about capacity, only about what it was. Barcelona and London Gatwick didnt even ask about what it was. Bag went right through no questions
I agree that an option is to have 2x 99wh and 1x 160wh pack, but I dont see how understating the capacity could get them banned. They either let you pass or they dont. If they have equipment to test, its still gonna be yes or no. Nobody was put in harms way by being over the limit per pack.
