Multi-Parallel Battery Charge

Hi all: Could someone shed some light on my idea of charging a chain of batteries while still connected to the load..?

I mean this:

|--12V Charger--| |--12V Charger| |--12V Charger--|
|------Battery-----------Battery------------Battery----|
|---------------LIVE LOAD DC Motor-------------------|

Do you think it may work? Anyone foresee any reasons why I should not try that?

There would be all LifePo4 Cells in series nearly up to 100V, and multiple 12V alternators..

any thoughts on this are appreciated

Thanks,
TechieatWork

The first question that comes to mind is "Why?". If you have a load and you have a power outlet, why cycle the batteries? Isolate them and charge them if needed, but ???

thanks dcb for the reply.
the main reason is: I wanna go completely off grid.. In normal petrol cars, alternators re-charge the single battery.. for my setup I will need multiple batteries and the mega mamoth DC motor (the load).. I am contemplating recharging with generators similar to the ones used in solar installations.. each generator for each block of 12V cells

I hope I am making sense..

There's not enough specifics to really say much here.
