I forgot to tell you what I ended up ordering:Right on. Thanks for the advice. I'm not putting another BMS order in until I'm sure of the specs.
In the message you posted above from Daly, I'm curious why you want the charge voltage cut-off at 2.5 instead of something higher like 2.7. Wouldn't having your charge voltage cut-off and balancing voltage both at 2.5 potentially mess with the BMS ability to balance. For example, say a cell reaches 2.5 while the rest of the cells are under and the BMS cuts off before it can balance. I was thinking of asking Daly to do the balance of 2.5 like you have, but the cut-off at 2.7 (which would be the natural high-point for the tech).
LTO 24S 64.8V 40A w/common port. Cut-off at 2.7V
This should be the best setup for the Daly's to function properly with these batteries. My advice would be to run your system without any BMS for a year and check each cell for balance at that point. It would be easier to prewire your batteries for a BMS and use it to test each cell with your tester leads. Then, if you find some out of balance get a BMS.
I was told to get a couple of them made and just use on a battery that had out of balance cells after a year. I just didn't want to have to bother with them but it would have saved me unnecessary expense. You can use me for your Guinea pig if you desire.
