Re: [electricboats] LifePo4 build questions

Sorry, these are the bars with nice rounded sides:

(Not that rounded sides are necessary.)  Aluminum 6101 is claimed by McMaster as 'Highly Conductive'.  I've used this McMaster part for buss bars in the past.

But 1/4" is the smallest thickness it comes in.  Overkill for just 100 amps.  In the 3/4" width it comes to 1.5x the cross-sectional area than my earlier suggestion.

The Aluminum 1100 material I used on the 10kWh battery in the video.  Had them built by eMachineShop (I have no access to CNC).
