The owners who were interested in the details plugged a voltmeter into one of the 12v outlets long before RT ever installed a voltmeter. Reported voltage readings seemed like a standard AGM charge...

From the reports I have seen from owners, it seems that the lithium’s are being charged using an AGM charge profile rather than the other way around. Not optimal charging for the lithium’s but good...

Yes, very true.

There is still the issue of powering electric battery heating pads from the underhood generator or shore power or solar for a cold van with the lithium battery bank below operating...

By “the battery “, I guess you are referring to the AGM battery or are you referring to the lithium battery?

In the scenario where the van is cold with the Ecotreks off and at a low enough...

The battery heaters seem to be powered at the charge port so the relay is not going to effect it. The procedure for initiating battery warming was to simply start the engine and the underhood...

As I recall, the addition of the AGM to the Ecotrek system was done pretty soon after the introduction of the Ecotrek. But my memory is not that good these days so I may be mistaken... :)

It has another purpose, it is needed to excite the alternator or solar charger (or shore power charging in this new configuration) when you need to power the battery heaters if the Ecotreks are shut...

It would seem there is no other control available to the BMS than to disconnect the ports?

As far as I can tell, my Mastervolt lithium system has all the components on a network with the lithium...

With the inverter moved to the charge port then shore power charging would get disconnected from any Ecotrek that is fully charged but the AGM would always be connected to the shore charger.

If all the charge sources are now connected to the charge port, the BMS prevents overcharging by simply disconnecting the charge port. After the batteries reach some discharge point the BMS...

The likely reasons for the shift are to prevent overcharging when on shore power or to allow the battery heaters to be powered from shore power. The inverter will always see the AGM battery on the...

I would hope that they shut down the charge connection when they get to some low voltage to prevent complete discharge. I expect they decided that preventing overcharging on shore power by moving the...

In any case, the total run time for the Air Conditioner is the same for either voltage trigger point. You get the energy prestored in the batteries and the energy from the VoltStart cycles and as you...

Very good, I don’t have Ecotreks or VoltStart so I base my guesses on owner reports and you have the results to show the Ecotreks shut down before the inverter. Since RT has control of the BMS design...

I think they increased the voltage trigger for VoltStart in order to avoid having the inverter shut down due to low voltage when there is a high load from the air conditioner. In the end, it really...

I won’t attempt to conjur up Roadtrek’s reasons for not including SOC info in the basic Ecotrek system but I would guess it is a matter of cost (due to the modular design) and their assumptions that...
