It's mostly cooked, but take a look at the following BLF
thread. It may be of interest to you:
The making of a BLF charger: the start of a new venture
It's gonna have
a lot of advanced features while aiming to avoid being overly expensive. We'll see.
Thanks for posting that link!
A great feature set but the actual implementation will be critical as many chargers have a lot of those features but they do it verrrrrr poorly. Under $50 retail means that it probably needs to cost less than $20 to make, and only if being sold in huge quantities.
It’s possible, but as you mentioned they will need a 4-wire IR setup and that will not be cheap to do robustly. Add on fans and a very expensive power power supply to be able handle the huge input-output voltage ratios and costs start creeping up.
Not a lot of talk about accuracy tolerances, safety, robustness/reliability, assembly quality, QC practices, etc., though. That kind of stuff gets expensive. I realize it depends on who they get to manufacture it but these things need to be part of the requirements, not something to hope the company does well enough.
I’m cautiously hopeful and would love to see it. Making the code Open Source and the unit programmable would offer great upgrade paths. Would any company agree to make it then? Perhaps not.
We’ll see what happens in a year or so!
