Yes, the RT Voltstart works on both AGMs and Lithiums. But they are programmed with different voltage trigger points. Unlke your autostart, it isn't user programmable with respect to depth of...

Why not try leaving one or more of the batteries on line when you plug in shore power and see if the Volt Start no longer behaves the way you describe?

The volt meter RT is supplying is a three...

In what position do you leave the battery off, the individual lithium battery modules and the inverter switch? I vaguely recall a u-tube presentation that indicated that for shore power charging that...

IMO, among the best of the breed are the Balmar units. Perusing their site reveals something of interest which is that they have hot ratings like all alternators, but the percentage of derate is not...

The answer doesn't seem easily arrived at.

DC Power claims only a 10% reduction for running hot which is pretty good.

However, if their figures are correct, the real world AH capacity...

Man, that thing is HUGE !

With respect to discrete BMSs vs. a master BMS, maybe there are some tradeoffs. It's a no brainer that a master control system is going to be more energy efficient. But...

When I previously suggested that hopefully RT would mitigate BMS losses by developing a master BMS, some folks chimed in that a master BMS would not work well but by your description, you have four...

Thanks for the details on the ARV setup. Are you using multiple batteries and if so can you take an individual battery on and off line?

Absent any other load, what is your estimate of what power...

The question was only half serious. Requiring 3 amps to support a lion BMS would deplete the practical capacity of a 200 ah battery about 40% over a 24 hour period which is outlandish if that is...
