Good advice - I picked up a small LiPo Battery Bag from Amazon.

One of the main failure modes of Li-Ion batteries is trying to charge a
defective battery ( puffed pack). When Li-Ion batteries begin to fail one
or more cells develop a high internal resistance and heat up during
charging. The 2hr warning is likely driven by the danger of trying to
charge a bad

I put a battery in a steel pan out on the concrete patio and charged
overnight - the LED went Red to Green overnight and the battery was still
cool in the morning, so all went well.
The timer sounds like a good solution for indoor safe charging, but I'll

Hi Bill:
One slick trick I’ve done with chargers is to use one of those timer switches…
the type often used to turn on and off interior lighting, to make it appear
that someone is home, when they are not home. The model I have uses some
plastic pins, color coded, to set the “on” time, (green)
I would get a timer switch, set it for the recommended charging
time. and run the charger off that switch. If you get back
before it starts charging again, all should be well.

Interesting question. In just received my kx2 today. I ordered everything EXEPT
the kxbt2! I don't know how I missed that so I'm ordering it this weekend.
Can't wait to get on the air with it

Yes, with Lithium batteries, follow the instructions.
If they do not recharge within the specified time, something is wrong.
Whether that specified charging time is 2 hours, or something else is of
no consequence. If it does not charge within the specified time, it is
cause for investigation or
"Do not continue charging the battery if it does not recharge within the
specified charging time. Doing so may cause the battery to become hot,
rupture, or ignite."
Does this mean the battery should not be charged more than ~2hr to full
charge? So it shouldn't be charged overnight?

There may be DC chargers that are compatible with the KX2's battery pack. We're
looking at a few. Until then I highly recommend using our inexpensive fast
charger, which is designed specifically for this application, with all required
monitoring and control circuitry to ensure safe operation.

I charged my Li-ion batteries by a voltage regulator LM317 set to 12.6V.
Never a problem and the battery lasted but the regulator needs a sink.
It would be really convenient to be able to charge (even slower) without
removing the battery.
It would really be nice to add internal Li-Ion option to
I feel kind of stupid buying a charger when I have a very expensive bench
power supply. Does that battery pack have a balancing circuit and over
voltage protection?
