Re: Laser battery processing

I've been really impressed with that style of interconnect for prismatics. Great joint strength that tears the bus bar metal apart trying to remove it (unless you hole-saw from above right on the weld nugget area). :bolt: That prismatic looks like its got both terminals aluminum, very convenient.

Re: 75-5 ZERO MOTOR REWIND

The single controller idea i see as a temporary loss of sanity Doc. I for free will send you a second BAC8000 my friend to help you find rationality my friend. You have no excuses in asking for higher phase current controller options if you would choose not to double phase current by running a seco...

Re: 75-5 ZERO MOTOR REWIND

If you can find a controller with more phase current, perfect time to go 3 turn. . I plan using one of my BAC8000 and max it out. The last specsheet 2022 from october mention it is now max 86V instead of 90V so i will use 20 or maybe 21s ( if at 4.15V) The max batt current is also mentionned to be ...
