MMM amp draw vs HV-110 amp question

[Over_revO]

Hi guys,

I am trying to learn about eletrics and had a question about the amp spec of the esc,

on castle it say the MMM have 120A continuous,
it also say the HV110 50 volt have 110 max amp draw....

Is it the same spec? what that mean...

I know it can handle 50volt and the MMM 25.2volt, but what those amp rating stand for?

Some batteries say 150 amp continuous .... im lost on that a little...

Trying to find a good setup for a friend, he want the Neu 1527 1d 2300kv
it handle 26 volt, but he want a good esc to handle that and more if he decide to get something stronger...

Thx for any help and explanation... :)
