freelancer, you are a jem.
But I got to ask...
what was the power source when
- you charged the radio without the cradle
- operated it.
cos in the manual there is explicitly state the the radio should not be operated with the charging adapter.
You really want to regulate charge current to about 200 Ma .
It is a 7.2 volt 1600 Mah battery and charging at much over 200 to 250 Ma will cause battery heating issues and likely shorten battery life.
maybe, but it is withing the sepcs of Nimh to be charged at even 1C, and usually a charge of 0.5C is suggested.
Even so, the guy I mentioned is among other things SAR medic, so ability to operate precceds battery life within certain bounds
BTW I may have made my own powerbank but there seem to be some
ready made options.
Some even advertise amp capability at 2-3.2A!
