Happy Breffast!
Some server rack batteries actually have a buck converter and will regulate the current. Usually it drops it to 10 amps.
I've not encountered this. I've only dealt with Pylontech and Trophy interfacing directly with a GX. In those cases, they effectively regulate current, but that's outside of this context.
In the case of a buck converter, then they simply present themselves as a load to the charger, no? The charger will simply deliver whatever voltage and current the converter draws within limit. I have a hard time imagining this would cause an issue with the way most chargers operate.
These cheap 12 volt batteries only have on and off switch though.
Yeah the power supply is wise to have. Especially in these situations. And especially when people put them into series
I can't fathom living life without the tools I have for this stuff. I know lots of folks just want a basic setup and don't want to be anymore involved with maintaining a battery than they are with the 12V in their car (Install. Replace when needed. Nothing in between), let alone learn the nuances about the "drop in" LFP batteries, but the right tools and process boosts confidence and can eliminate a lot of headaches up front.
