Voltage regulator

[K Sarich]

Do you have the Alternator high amperage output connected to the coach or the chassis batteries?

It is connected to the a chassis lug, but both systems charge/combine when the ignition is on. When doing the install our thinking was program for the house Lithium batteries and if the chassis AGM batteries suffer then just replace them with Lithium. So far no problems, which is good, as the price of Balqon's batteries jumped up soon after our purchase. I believe there might be more of a problem if our chassis batteries were wet cell, but since the charge profiles between Lithiums and AGM's are similar they seem to get along fine.

Do you have the regulator sense wire connected to the corresponding battery bank?

Sense wire is hooked to the chassis battery lug. We placed it there thinking that there may be times I'd run the engine and not wish to charge the house battery. We then discovered if the house battery is off the bus no start. Don't know why BB designed it that way, must be a reason. I guess I could switch the sense to the house battery, but it would still be combined when the Ignition is on.

In my Prevost I have two alternators. The 24V 50DN is dedicated to the house batteries. Then I have a Bosch 24V dedicated to the chassis batteries. Each has their own regulator and a sense wire respectively.

Having dual alternators feeding each system independently would be nice given the different battery technologies, but no such luck for us. If one of your alternators failed are you able to combine or switch the charge to each battery bank?

Were you able to use one of the user selectable preset programs or did it require further customization?

No. There is no "Lithium, Lifepo4" setting so we did customize.

Page 9 of the manual lists all the different pre-programmed settings. They are all there plus a few I din't know about.

Is there any in-house monitoring of the Balmer charging stages?

No, but I didn't look into whether that option might exist.
