Re: FT-897 and Solor Power to charge batteries
- I've used a shunt regulator to limit voltage across a battery under
charge, and such might help here (with a Zener/fuse crowbar for
insurance if the regulator fails open). This approach does require a
good heat sink, however; you may have to dump all 23 or 30 watts into it.
