Kevin,

can you also publish specs for terminals for new 160AH and 200AH cells? Are they threaded holes or threaded posts? What thread size, hole size, etc?

Also, are all cells listed in your table 3C type cells?

Asking a public forum for preferences is a futile effort, there are more opinions than forum members

When you start selling your new cells you will see which ones are more popular, based on orders.

Also, Thundersky and CALB cell dimensions have become defacto standard in the DIY market, so the closer you get to those the easier it will be to compete with them, that also includes terminals standards.

And, as I told you before, having inventory ready to ship from US based warehouse is probably the best thing you can do to gain US marketshare, assuming competitive price of course.

Thanks for sharing your new developments!

Kevin,

in my opinion, all your new sizes seem attractive. You can't go wrong stocking 40AH,60AH,100AH,160AH,200AH cells in US. All these sizes are used in conversions from bikes to cars to boats, etc.

Please add terminal specs, bolt size, thread, etc. to cells documentation.

Any idea of when new cells will be ready to ship from US warehouse and what will be the price per AH ?

I have to agree with JRP3, I don't think you need to copy lead acid sizes. Lithium batteries can generate their own new size standards because they will be so much smaller for a given battery pack capacity. One exception to that may be the Golf Cart battery sizes (GC-1, like the T-105) because there is such a large installed base of a single size. Those are used in more than golf carts and old EVs.

I think you misunderstand Kevin's message. They are not copying LA size, but they want to conform to at least 2 dimesions of common BCI Group sizes and then let 3rd dimesion be whatever it is based on LFP density.
Current prismatic LFP production has pretty well defined density, there haven't been any major improvements, so its just a matter of compromizing given volume across 3 dimensions. You pick 2 desired dimensions and the 3rd is determined by required volume to pack it tight with LFP material.
This makes perfect sense. Remember, EV conversions is a small market, any LFP manufacturer has to shoot for competition with LA in ALL markets, including Golf Carts, solar banks, boat and RV housebanks, etc. All those markets are dominated by standard LA batteries, so if 4 LFP cells fit nicely into LA volume with some room to spare, its perfect for those markets. But their current cells are too tall and don't fit well, hence their desire to change their molds.
