Re: KX3 batteries

IIRC, the Eneloop Pro has fewer recharge cycles than do the regular
Eneloops.

Re: KX3 batteries

In reply to this post by John Harper

The FAA rules on taking batteries on airplanes can be found in the
document "Batteries Carried by Airline Passengers: Frequently Asked
Questions" at
www.faa.gov/about/office_org/headquarters_offices/ash/ash_programs/hazmat/passenger_info/media/Airline_passengers_and_batteries.pdf

"Lithium ion batteries (a.k.a.: rechargeable lithium, lithium polymer,
LIPO, secondary lithium). Passengers may carry all
consumer-sized lithium ion batteries (up to 100 watt hours per battery).
This size covers AA, AAA, cell phone, PDA, camera,
camcorder, handheld game, tablet, portable drill, and standard laptop
computer batteries. The watt hours (Wh) rating is marked
on newer lithium ion batteries and is explained in #3 below. External
chargers are also considered to be a battery.
With airline approval, devices can contain larger lithium ion batteries
(101-160 watt hours per battery), but spares of this size are
limited to two batteries in carry-on baggage only. This size covers the
largest aftermarket extended-life laptop batteries and
most lithium ion batteries for professional-grade audio/visual
equipment."

Last month, I took a KX3 to Sint Maarten (PJ7). My battery was a Bioenno
6AH, equivalent to 72 watt hours. It worked like a charm!

You need to check with your airline, as some -- but not all -- airlines
will allow you to take a battery as large as 160Wh. The larger Bioenno's
(9AH and up) are over 100 Wh

Bioenno has listings on their website of recommended batteries for most
commonly available rigs, based on your duty cycle.

Charge before you leave home (all Li batteries require a charger
designed for their specific chemistry, voltage, and capacity), connect
to your KX2/3 external power jack. Choose the capacity/weight that
suits
your planned use.

$50 will get you 3Ah that weighs 13 oz; add $15 for the charger. A 6Ah
battery goes for $80, approximately twice the weight. I paid about $195
for a 20Ah battery that weighs 5.4#, +$20 for a faster charger.

Re: KX3 batteries

I've brought the 3 Ah ones on aircraft multiple times and had no issues. I
brought a copy of the UN safety certification that I got from the battery
company but have never been asked for it.

The batteries did save me from having my bag checked once though. I put my
bag in the overhead. Someone else came by and moved my bag trying to get
theirs in the overhead and the overhead would not close. The flight
attendant, not knowing what happened wanted to check my bag. I stated it
had lithium batteries in it and she checked the bag belonging to the person
that moved my bag. I didn't have to argue at all. Karma!

LiFePO4 batteries are also safer than other Lithiums, but they seem to be
treated the same by the airlines and shipping companies.

I think Eneloop Pro have a higher internal resistance than the regular
Eneloop. In my experience, using both of them sequentially, the KX3 went
more quickly to the enforced 5 watt maximum output with the Eneloop Pro
cells compared to the standard Eneloop, despite the higher ultimate
capacity of the Eneloop Pro. But, YMMV!

Re: KX3 batteries

Will the Bioenno batteries have enough terminal voltage to get the 15W?
I'm looking at a 9Ah unit and if so will stop by Gigaparts on the way home from work today and pick one up.

Re: KX3 batteries

LiFePO4s will stay at high enough voltage for most of the discharge cycle
to keep the KX3 above 15W. 9Ah will run it a long time.

Mark
