Why did the balancers have to be changed?

The first one was replaced because the center was cracked and made less tension on the belt which caused the battery to die. It worked for about a month, Then the second one started wobbling like it was a defect and now the third one is doing the same like something is bent. Hope this helps on giving me advice on how to fix

That's pretty much unheard of. I would question whether something is wrong with the crankshaft leaving the Balancer loose on the shaft but there is no reason for a tight balancer to fail like that. The only way they fail is if the rubber attaching the 2 parts rots away and that's not happening on a brand new balancer.
