hi everyone
I know the best way to power class d modules are probably lifepo4. but they are too expensive at 20euro each batteries.
what are my option for around 50$ in order to have, some of, the best way to power my modules?

for $12-20 dollars, depending on amp hour rating an SLA would work fine.

Use this with 10 1.2v AA rechargeable Batteries.
