PSA: Battleborn

Yes, but on a short run from a charger to battery, say 10’ at 100 amps, you can use AWG 4 to be at 3% drop. That’s still lots smaller than the 1/0 that BB call out as adequate in their paper.

I don't put much faith in BB engineering.?This is the same company that suggested 30 min of extra absorption at 14.6V for every additional batts in parallel.If they are in parallel they will all hit absorption at the same time soil 30minis fine for one batt it is fine for four in parallel. The next hit to BB is all the folks suffering from capacity degradation..

BB admits this is a novel approach, but doesn't claim it to be patented (or maybe I missed it). If it is such a good idea and not patented, why aren't more battery manufacturers using it?

One more curious thing - they say they used PA-765 inside the terminal because that type of plastic will soften at just the right temperature and in just the right way to open the circuit and let the aluminum oxidize. They also say having the lid in place is critical to the safety of the design by holding the terminal assembly in place. But then they say the enclosure is also made of “PA-765 ABS injected with a flame-retardant additive”. So wouldn’t the same heat that could melt the “fuse” also melt the case, disrupting the stability of the terminal just as badly as removing the lid could?
