Why Lead batteries do not need balancing?

In fact, sealed lead acid batteries need very strong balancing on every charge cycle --- in order of 100 to 1000 times stronger than what li-ion needs. 6-cell (12V) SLA is the biggest usable unit that can balance itself through the slow recombination of H2 and O2, but even then you need to regulate voltage and current very carefully.
