Here is my work in Progress. 48v 60kw split phase 5k and RS450
progress.
No BMS on the cells?
Looks like it!!
That’s a ticking time bomb!!!
You absolutely need to retrofit a BMS!!! For example, a REC BMS or another BMS that connects via Battery CAN and supports a master–slave configuration!!
The battery compartments need to have protection against accidental contact fitted in front of them!!
No cell compression needed for these prismatic cells ?
Yes, yes, it is clearly stated in all the manufacturers’ documentation.
No BMS, no cell compression, an epoxy interlayer only on one cell bank—I find that particularly daring, if not downright dangerous.
But then again, it’s not at my place

Patrick.
