Bruce,
The answer is yes. There are several choices, but here are two basic ones.
1) Use a power supply that you can adjust upward to the 13.1 to 14.3
volt range to power the K2. The internal battery will charge, but it
will take a long time to come to a full capacity charge.
2) Make a direct connection to the battery and use a 2 or 3 state
charger designed specifically for charging gel cells. The A&A
Smartcharger is one example. You do not have to drill any holes - use
the existing transverter holes in the top cover to mount the jack for
the direct battery connection. Be sure to put a fuse inside the K2 when
making the direct battery connection, if the external connection is
shorted in any way, one would find out just how much energy is in a gel
cell - molten metal, flying bits of hot conductor pieces, and other bad
things will happen. Even though the voltage is low, it is still
dangerous because the current capacity is huge.
See my website www.w3fpr.com for information related to 2) above.

Hello all,
Is there a simple off the shelf model of battery charger which I can
buy or build that will properly charge the K2 battery?
I'd prefer not to drill a hole in the rear apron, so I'm looking for a
commercial solution, ideally with an adjustable output.
What have you found that works, or how did you solve your K2 battery
dilemma?
Thanks!
