No, he doesn't mention that in the vid I linked to, I've never seen an alternative build method and thought that they'd always been built with the plastic spacer, have you got a link?I'm not sure if that videos says, but he checked the original battery and it didn't have the plastic 'spacer', so it seems not all these batteries are made the same.
Absolutely terrible design. At 100A there's bound to be heat generated at that critical joint. The bolt will expand, the plastic will soften and deform and the resistance of the joint will rise. The raised resistance causes more heat and now you've got a runaway effect and the result is self destruction. The critical avalanche point will probably never get reached at lower currents so lighter users will probably escape the problem but ultimately BB rate the battery at 100A continuous and clearly it doesn't meet that spec.
From what I can find it seems that the 100Ah batteries have always been built with the plastic spacer and they use/used an alternative build without the plastic spacer on the larger sized 270Ah.I'm not sure if that videos says, but he checked the original battery and it didn't have the plastic 'spacer', so it seems not all these batteries are made the same.
It seems very odd that they should use what appears to be thermoplastic in that way, you might get away with it if using SRBF, or SRBGF, but even then I not sure you would sandwich it in that fashion.From what I can find it seems that the 100Ah batteries have always been built with the plastic spacer and they use/used an alternative build without the plastic spacer on the larger sized 270Ah.
I've been watching your updates on your Youtube Channel and it is amazing how poorly such a well regarded brand is performing and how this seems to only just be happening recently.
