Johnny,
While this is a good suggestion, given the age of the K2 and the lack of
engineering time for the Elecraft designers, I don't think it will be a
change coming from Elecraft.
It is however a good suggestion to reduce the weight and operating time
for a portable K2/10. I think it would be a good mod for some
enterprising ham. I don't think an internal charging circuit board
would be necessary. Check out the direct battery connection on my
website www.w3fpr.com - Smartcharger for the K2. With a battery
replacement, the Smartcharger part is not relevant, but the direct
connection to the battery is relevant.

Similarly, with the advance in battery technology, the lead acid battery in K2
should be now advanced to a LiFePo pack as well. There are ample space inside
the K2 for installing a new charging circuit board. This will greatly reduce
the weight of a battery powered K2 and give much longer operating period.
