Im living in 12V land. What will happen with 24V la and lfp series combo?

Different resistance etc. The LA will limit the LFP. Same principle as a shaded panel in a series array. Your performance only as good as the worst performer.

But will it work or will it explode when trying to run a pvr Dstv decoder?

It will work but you will kill the LFP quicker since the LA will drop faster. Also charging will be an issue. Old and New LA in series would make the new battery age very quickly as the older one will charge and discahrge much quicker, not sure if the same principle will happen with new LA and new LFP.

1. You can’t kill lfp.
2. LA will perform exactly the same as
it’s the lowest common denominator.
3. It works as your doing 0.1C already.
4. Replace next LA that dies with LFP.
5. We not talking about mixing old and new LA’s in series.

Noone in their right mind would connect LFP and LA together in series. How will you charge them?

And why buy LFP and have it limited by LA? Some things are best not done.

Sure, but it can be done. All operates as before. Im tempted to make a YouTube video seeing no one has been crazy enough to attempt it. Then I can be YouTube rich.
 
Yea i think a person can mix LA and lfp in series

Not that scenarios will come around often that require it

And i don't think anything will go wrong apart from losing half the lfp capacity. If you only use 50 soc to not hurt the LA

But yea sure it will be a nothing burger

Unless you run balancer then all hell will break loose

Would have to manually top balance from time to time

I don’t think it will just work. LA has voltage drop and Peukert effect under big loads. The lithium battery voltage will remain relatively stable while the LA keeps getting pulled down worse and worse.

Will it damage anything? Maybe not but you won’t get much out of it.

Yea sure it does but the amps is constant irrespective where you measure it on the series line

So yea it will just work the voltage
Of the 2 batteries will differ as they go througb there soc and vkktage graph

Sure some.drift will happen as it is with any micturenog batteries and that is where the manual adjustmemy or ballance would have to come in

You can't slap a balancer on that

But yea i doubt it would be broken immediately

How long it will take for the drift to affect operation o fon't know

By that logic no remote would work with an old and new battery mix

And yet they do
the weak battery is still the weakest leak
