Hmm, that's a good deal. Any clue on these modules cycling before.salvage? Do they have balance leads/ports for implementing a BMS?

That *is* a great deal.

LTO could take any regen current I could throw at it, too, making it great for braking performance....

If they just weren't so big and heavy they'd be a great replacement for my SB Cruiser's aging pack, but I'd need to have two modules installed in the trike at a time for enough voltage to run the system (presently 14s2p EIG NMC for 52v 40Ah), and that'd be 126lbs and about two cubic feet of volume. (I think my present pack is about half that volume and a third that weight).

Still...gonna have to think about this (haven't seen any other good options that are worth getting yet, but I don't know how much longer my present packs can run the trike without carrying them all in parallel, which will be about the same as a pair of these LTO packs without the other advantages).

Yes, uses common plug. Comes with pigtails and acquisition pcb.

How much does a single module weigh?

Per the linked document in the OP, 28.4kg, or 62.6lbs.

Thanks for posting. Those look ideal for off-grid house power.
