Power Max BPCM Converter/Chargers ???

Understood, thanks!

The three-stage converters do not stay at 14.4 very long and revert to 13.6 as their normal voltage so the batteries will not overcharge.

The 12v items work ok in the 14s but the lights will burn out faster over time than if at 12. The Norcold fridge control has an upper limit of 15.4 DC. Inverters have an upper limit DC input voltage too, such as 15v but they have a shut off for that.

You disconnect the rig's 12v systems from the batteries when equalizing at over 15.3v.

o.k., thanks... I was just curios how being adjustable would effect it's overall use.

I have no need for, or experience with converter power. My bus is only 110v wired; powered by inverter/shore/gennie power. The fridge controls and heat fan/pump are 12v wired directly to batts, but the sink/shower pump is thru a 110v to 12v 5a converter plugged in to a standard 110v receptacle.

So it would work like any other converter when set to a suitable battery float voltage, but what are the standard operating voltage ranges of most 12v devices, such as 12v lighting, etc. ??? Would a 14.8v setting damage such devices? I've been curious about this for some time, now. How does the converter serve its intended purpose when it's charger feature is doing it's thing?

Thanks!

Hence this is why I smiled when I was given a WFCO. 13.2 volts is a good all around value for accessories and when the batteries need hammock-time. It's when battery chemistry stamps its little feet and demands to be mollycoddled is where most RV converters get confused. Treating this as separate issues makes battery management a whole lot easier.

Assuming these do not have a multi-stage charge function, how will these function as a converter, if adjustable voltage?

Just use the batteries float voltage when plugged in and not charging. That's what most converters do.

Would one have to leave it turned on, and adjust it to say 12v when not charging, so it doesn't perpetually charge the batteries? Or would you be best to set it at say 13.2v for perpetual floating?

Thanks!

To act as a converter, you would set it to some battery-like voltage so it could power your 12v rig. If the batteries are connected, you would want them on the proper float voltage for the temperature.

In practical terms, you need to mount the unit where you can get at it to twiddle the knob, so that can be a limitation. I use mine as a portable charger so I have not had to decide where it could go if it were used as the converter. Mine has a handle on top too, which might be in the way and have to come off.

The on/off switch it has would be handy if the unit is your converter and you want to run the inverter whole house so you need to turn off the converter.
