My experiences are with K1, not KX1 but may generalize if I can
manage to keep the form factor in mind. Also I use 18650 Li-Ion
cells but use figures for 14500 cells below, as 18650s are too
big for this application.
As others have mentioned, these cells require a specialized
charge-discharge
I would be really interested in the 8 triple A's NiMH with a charge
controller.
This with a an extra backpanel would make it easy to choose between time and
power.

LiPoly batteries are expensive, lightweight and very dangerous if improperly
charged. When things go bad with LiPolies, things can go very bad. I have
started using them on my ATS3. Here's a list of do's and don'ts regarding

Wow, from what I (briefly) saw at that link, why would anyone want to use
LiPos? Yes, they may provide some advantages but the disadvantages/risks
would certainly (in my mind) overwhelm the advantages.
LiPos are like gasoline, both can be very dangerous but with proper use and
caution,

difficultly sourcing

Hi Michael.
i do have a LiIon Hard Carbon external battery pack but i would not
use Li Polymers in my pocket because of the fire hazards.
i use 10 1/2 AA (250mAH) plus one regular AA NiCad in my KX1.
Send me an email and i will send you the modification details.
The KX1 is usually hand held so

We've located a 4-AAA cell battery holder that would fit inside the KX1
(one at each end of the bottom cover, as with the present AA holders).
8 cells would provide 10 or 12 volts, giving you significantly more
power output than 6 of the same cells (as much as 4 watts). The
tradeoff would be
i am still using NiCad's...in my KX1.
KX1 - 1/2AA NiCad Battery Modification...Rev. D.
Originally i had 6 'AA' NiCad batteries in the KX1 but i needed more power
for pedestrian mobile operation.
i removed 4 of the 'AA' NiCad batteries and added 8 - 1/2'AA'-250's (short
type AA) to boost the

I operate almost exclusively with 10 NiMH AA's and would like an
alternate bottom that holds that, if it fits in your production plans.
I would also like an 8 cell holder for the Lithium cells. I keep the
Lithium primary cells in place but use them only for RX or for when I am
using

Any input on such a product would be appreciated. If there were
significant interest, we'd try to have it ready early next year.
LiPo would be nice, for me: I am already using NiMH in the standard

A rechargeable battery system with a built in charger would have it's appeal
especially if it can be charged from many different sources such as 110/120
VAC 60Hz, 220/240 VAC 50 Hz, 12 or 24 volt automobile cigarette lighter
sockets, solar power, etc. If Braun can do it with a razor, just think
