I'm not saying that compressing is bad. It's just a waste of time and materials.Yes it could be argued that compressing with non compliant fr4 sheets etc is creating pressure hotspots in the face of the cells. So in that case having the cells freestanding with some insulating material between them would be better. I think the Victron LFP batteries are just cells in a plastic case.
A vote for the orange man would hopefully result in less red tape for us DIY ESS folk.Soon battery compression is going to become a political issue too, like abortion and climate change
So why would anyone pay a premium for EV grade batteries for storage vs less expensive “grade B?”It's not.
For solar storage, calendar aging is the only enemy.
But, if you are building an EV, then compression might help.
I know when people bought the grade b aesc 305?Ah cells from 18650batterystore back in the day quite a few had problems with bloat?So why would anyone pay a premium for EV grade batteries for storage vs less expensive “grade B?”
Better quality is better quality, no matter what the use.So why would anyone pay a premium for EV grade batteries for storage vs less expensive “grade B?”
Ya, but can buy a lot more storage with the money saved…Better quality is better quality, no matter what the use.
True, and some do go that route.Ya, but can buy a lot more storage with the money saved…
I was at $78 per cell for rept 280Ah. For me it doesn't make sense to pay $95.50 for an eve 280k v3.Ya, but can buy a lot more storage with the money saved…
A little birdie told me, that a new battery technology is waiting on the election results. Present powers at be, won’t protect patents from foreign competition. If it remains status quo, it’ll just move to China to start with instead of getting screwed by both countries and going out of business. “Paraphrasing”A vote for the orange man would hopefully result in less red tape for us DIY ESS folk.
Meanwhile the dedicated/solar refugees are moving to Kansas where NEC requirements are way back in the dark ages.
Kinda wondering what the performance difference and degradation is like between these. Any data yet or too soon?I was at $78 per cell for rept 280Ah. For me it doesn't make sense to pay $95.50 for an eve 280k v3.

True, waiting is a risk. However if you have spent millions on unique anode or cathode treatments, without proper backing and planning, submitting a patent is simply an open supermarket for thieves. Many have gone broke defending their patents.There is ALWAYS a new battery technology waiting in the wings regardless and the people with patents generally want to make money from them now before it is stolen. Doesn't matter what happens certain patents won't protect the knowledge. And with any new tech the time from release to copy is about 6 months
