I did hope i'd found the ideal source for these packs.. supplier called pt. besitang beng, based in indonesia. Found through the alibaba international trade website. Claimed to be able to supply me with 100 dewalt packs, including shipping to the uk for $3900. basically 30 dollars each plus shipping... unfortunately during my lengthy negotiation for sample shipments (i wasnt going to get burned) he sent his bank details, which were under a different name. searching for this name showed a few fraud warnings under various company names.. so i told him where to go.
I did think immediately that the price was far too good to be true, but hey, you have to investigate at least. if they were available at that price.... wow.
i wonder how much they actually do cost in indonesia / where the cheapest price might be had..?

Subject: [EVDL] Dewalt 36V battery packs
I'm buying a used EV, and I'm thinking forward to upgrading to M1s out of
DeWalt 36V packs.
If I've done my math right, at 3.3V x 2.3Ah per cell, a single pack
represents 75.9Wh. It would therefore require approximately 13.2 packs to
build a 1kWh pack and 132 packs to build a 10kWh pack. I can purchase brand
new packs all day long for $105 (shipping included) on eBay. At $105/pack x
132, it looks like I'd end up at $13,860 for my 10kWh pack. Is there a
better source/price for A123 batteries at the moment?
An area in which my thinking is very unclear is design, cost, construction,
and integration of a bms. Is there a tried and true open-source design
available (my father is an electrical engineer but he'd balk at designing
something from scratch)? If so, how much should I expect to pay in materials
for a bms for a 10kWh pack? Is there a reasonably sophisticated
off-the-shelf bms available for M1 cells? If so, who sells it?
Lastly, who needs a kidney? I'll need to sell one to pay for all of this...
