Good info is bears repeating, I rekon - lol.
I was trying to find that battery pic as I remembered the number but couldn't locate the pic. Thanks, fuceye.
If you can't get access to your battery because it is sealed and only have partial information on capacity and want to estimate the WH rating then you can estimate it as follows:
WH = Battery Voltage x Amp Hour rating
LiIon cells are typically 3.7V, but even if you don't know that (or the cells are stacked in series to increase voltage) you can estimate an upper bound of the voltage by reading the voltage off your DC charger (in this case it is 5 VDC).
The Equinox Battery Amp Hour rating is on the specs page in the manual = 5000 mAH which is 5AH. This also tells you that if you want an external usb battery charge bank it should be rated at 7500 to 10000mah or above in capacity (assuming 50% to 75% charge efficiency) to ensure a full charge of the battery (a good rule of thumb is to just get a charge bank that's twice the capacity of the internal battery and has the ability to put out a minimum of 2A from at least one of it's ports).
Most consumer electronics other than very large capacity, higher voltage laptop batteries are easily under the FAA 100 WH limit for small electronics that can be carried in checked or carry on luggage except e-cigarettes which are explicitly prohibited in checked baggage because they have a heating element.
Therefore, the max AH rating for the EQX is 5V × 5AH = 25 WH
Finally, contrary to what was posted in the thread somewhere, Minelab has put out information stating that removing or replacing the EQX internal battery in and of itself does not void your warranty. However, if you screw up the internal water seal o-rings in the process of doing so and subsequently suffer water intrusion damage, that's on you. So only attempt it if you know what you are doing.
