Re: Tesla MIC (made in China) Model 3 will be LFP!

Im sure Tesla have their reasons for this decision, but it begs some questions as to their previous justification for self manufacturing their own cells..
EG..
Superior technology
Lower cost
Quality control
Vertical integration of manufacturing processes
Etc, etc..
And poses the question ....why ?

Re: What trolling motor to start with on sailing dinghy?

Sorry, but i have no experience with these motors.
There must be a fishing/boating forum site somewhere with more experienced users.
However, in my experience hoping something is “just enough”.... usually ends in dissapointment ! :wink:

Re: Lipo vs Lion

Up to a few years ago, we used to have a member on here that worked inside 123 and had all the data on pouch cell compression tests.
Maybe if you search back enough on “A123 compression” you might turn up a few nuggets !
PS: the Leaf pouches are not under compression inside those aluminium cans !

Its no easier than designing an ICE for optional controls...
there is not much direct interaction between the driver and the engine /gbox in a modern auto
the compliance testing for different countries is likely a bigger problem.
