At the moment, as you can see, those on this side of the pond, are trying to sort out a reasonably priced source for a plug & forget charger. Plug & forget really means this - the charger is left permanently plugged in & charges the batteries when the box is switched off & stops charging when the batteries are full so no risk of overcharging. It means you can enjoy the benefits of batteries without concern about charging.
I have tried to order a batch of chargers from both these companies but they insist on either using UPS or Fedex (& the associated rates > $100) or USPS without any insurance protection & I'm not willing to risk hundreds of dollars. Jeez, talk about not wanting to do business
.
I have used discarded mobile phone chargers (< 3.6V output) but they don't run off automatically & so you run the risk of overcharging the batteries which will shorten their lifetime. I forgot & left one on overnight - no fire, no explosion but the battery read 5.?V in the morning - I discharged it down to 3.6V but suspect it's robustness. I also would not have liked the consequences of connecting this to the Hiface with chips expecting 3.3V (up to 4.0V max) - it would possibly have killed it.
So this is a cautionary way of doing it until a suitable solution is found or I develop something.
