On a more important note:
A 70Amp alternator is undesized for charging a 220Ah house bank and
will never fully charge the bank, which will lead to premature battery
failure.


Where do we FIND these guys??!! A 10A battery charger, hell even a 2A
battery charger will charge a 660AH bank of beasts! It just takes
longer....

The slower you charge them...the BETTER they charge as the chemical
reaction to charge them is a slow process, itself.

As long as his load is less than 70A, which I'm sure it's much less, those
little 220AH batteries will charge just fine.

NOONE CAN CHARGE A LEAD ACID BATTERY IN 20 MINUTES NO MATTER HOW BIG THE
ALTERNATOR IS! The chemistry is just too slow for this old wives tale.

Geez.....
