I am a 6th-level Life-domain cleric. I have 1 hp left in the pool of 30 HP from the Channel Divinity: Preserve Life feature:
Starting at 2nd level, you can use your Channel Divinity to heal the badly injured.
As an action, you present your holy symbol and evoke healing energy that can restore a number of hit points equal to five times your cleric level. Choose any creatures within 30 feet of you, and divide those hit points among them. This feature can restore a creature to no more than half of its hit point maximum. You can’t use this feature on an undead or a construct.
I use the 3rd-level spell Beacon of Hope which allows maximum healing on anything:
For the duration, each target [...] regains the maximum number of hit points possible from any healing.
Will giving 1 HP worth (of this pool of 30 HP) to someone heal them 30 HP (the maximum for that pool)?
