Question Blacktip 12 AH Batteries ?

[Wibble]

Where do you get the paperwork for IATA compliance?

The DeWalt 9AH batteries are great and easily under the minimum required ***

See here:

Dcb609 air travel documentation

I am planning a trip soon and want to get ahead of all the possibly set backs. I have a blacktip travel in which I use the dewalt 20v 9ah flex max battery (dcb609) I have seen some people mention travel documents and specs for the batteries. Is there anyone on here that may be able to point me...

Ok so I'm back in Mexico and I had to ship the batteries as the airlines had 0 exceptions for me to exploit. It was fairly painless but worth it. Unfortunately you need to be careful because of the formula they use. A battery cannot exceed 100W hours and the formula is multiplying the battery’s voltage by its capacity in ampere-hours (Ah). If the capacity is shown in milliampere-hours (mAh), divide this number by 1,000 to convert to ampere-hours, then multiply by the voltage to convert to watt-hours.

So even a 9ah won't fly (pun intended) 9X20...

I just shipped my 12's.

They're not 9ah/12ah with the red shield in place.

I believe they're 3x 3ah or 4ah packs in one at that point.

At least that's how dewalt got around the limitations.

Trying not to feel like an idiot..... I just need to ask... you can have this debate with a TSA agent? To be fair, I read the statement literally and just did the math which would be my fear with the TSA agent. Is there paperwork that has this magical claim of which you speak that I missed? I mean that's awesome honestly.

In case anyone reading is wondering, it cost me $100 US to ship from Austin to Merida and about $20 in "Mexican Tax".

So only one of the Explorer 20ah batteries is needed but two of the Dewalts are required -- is that correct? And the 20ah cannot travel?

Yes that is correct.
A pair of dewalts makes 36v 12ah
This is 36v 20ah.

I used the same batteries to create my own packs: Samsung 21700-50E
Just 2x10 batteries instead of 40, so it's a 10Ah pack. Currently giving me a runtime of 100 minutes, so the estimate of 205 minutes on their pack sounds right.

The websites states that there's a ton of development done on this pack. Waste of time if you ask me. Over the last years, e-steps are becoming more and more popular, and they use the same engine, same battery packs.

One of those companies is Xiaomi and their e-steps use 10 Lithium batteries in series as well. With a good battery management system and a safe charger, for a price that's not even half of that BT-20Ah.

Adapting such a pack for a blacktip isn't rocket science, it just needs an extra cable (the blue one) connected in between the 5th and 6th battery.
