Anyone have have experience with the HKB Electronics MK4 Adjustable Regulator? I want to run other batteries and the existing charging voltage is barely enough to charge a factory lead acid. I have two AGMs I've been holding back.

@Markuson - can you share any additional information about the user variable unit - how it works, the range of adjustment, what output you are getting, etc. I put the non-adjustable HKB diode in and have been happy with it, but I'm still putting out at the low end of the voltage Odyssey recommends for their AGM. The auxilliary is fine, since the BCDC steps up the voltage, but I've been curious if the adjustable HKB unit can be used to up the output by another couple of tenths of a volt while charging the primary battery.
You can just make one. Instructions around here somewhere. Takes about 1/2 hour. Requires an add a fuse and a diode .Thanks all, I appreciate the advice and was about to purchase...but they are on backorder. I asked the for a status update and will report back.
I don't know that the BCDC is the only way, but I do know that is what the BCDC does. I have the 1225 in my LC.If I understand correctly, these drop the voltage level as sensed by the alternator so that it thinks it is outputting less than it actually is. As a result the alternator will compensate with a higher voltage output to bring the measured voltage up to what it thinks it should be. Net result is the alternator outputs a higher voltage.
So given this there is no way to increase the voltage to the aux battery while leaving the starting battery alone? For that I would need a more sophisticated voltage regulator, something like the Redarc BCDC?
