triac 12v 220v

I think it's another idea for transformerless power supply. You can try it with resistive load before working with the Batt. And please let us know your experiment's result.
Yea, coupling batteries via rectifie-bridgein serial to 2 KW heater...

don't try this depend of risk for electrical chock and destroy batteries
with overcharging...

12V may be to low voltage for this application.
Better use a transformer, say 220-15V, use this dimmer/triac on the primary and a diode or bridge on the secondary.
So your regulation will occure through primary...
but... check transformer temperature, is increasing to burning
temperature very quickly in half/quart load depend of high
peak current and heating magnetic cores depend of overtones
from Triac...
and for charger, is very small adjusting area for charging regulation
depend of only small part of voltage peak value is usable
to charging batteries - and give very high peak current if
you want 10 amp avarange current..
batteries is not same as heater, halogen light, or resistive loads,
is this elecrical character more simular as big Zenerdiode
around 13 Volt.
