Default three 6V SLA for powering TPA3116

Hi there,
has anyone tried to power TPA3116 or TK2050 with 3 x 6V sla batteries. That gives us 18V (acutally 3x7.5 = 21.5V) which should be pretty good. And they are cheep...8A are about 10eur = 30eur or 4.5A for 23eur.

My question goes to to charge them?... is it possible to use 12V charger and step it up to ???.

Thanks ,
