Well I suppose you could argue about the presence or absence of power sources in a definition of thermal runaway. In electronics thermal runaway , is where increasing temperature causes a situation...

LA batteries if over driven in absorption mode by a powerful enough charger , ie by allowing super high absorption voltages , will induce a failure state where the battery rapidly heats up...

There's no such thing as a" digital" one that can put out 12v under all conditions.

F the source has the power to feed current to the load in sufficient quantities it can determine the load...

The characteristic impedance of LA batteries during recharge at low SOC is such that most alternators will full field . But not regulate ( you may have protective regulation due to heat etc , but...

Re: Alternator Positive Wire Sizing

[

glad to see someone is thinking correctly.

This is why alternators or any current or voltage source do not set battery terminal voltage unless the " battery lets them". At low SOC the...

We are , impedance has a resistive and a reactive component at DC the reactive component is zero, but only in theory as all circuits have AC characteristics due to pulse activity.

, I was addressing the negativity around diode splitters and voltage drop

Maybe I got my English mixed up, I was referring to using diode splitters and sensing from one battery, not 1-2-both...

A large battery bank essentially controls the terminal voltage as its by far the lowest impedance compared to the output impedance of the alternator. In bulk phase the impedance is so low that...

Re: Alternator Positive Wire Sizing

NO,

whats likely to happen is that the regulator will have a lower output becuase the alternator thinks the battery is charged, but since you are charging the stater battery , does this really...

Re: Alternator Positive Wire Sizing

Hang on,

if you battery sense the starter battery ( being the most charged battery), but charge the domestics, all you do is set the maximum regulated voltage at the starter level, ie teh...

Re: Alternator Positive Wire Sizing

Voltage drop causes longer charging times, not undercharging per say.
