Yeah, as Eric noted, I meant to say 40c/wh.
These are surplus modules for 2011 THINK City electric cars (which I own/drive).
Since I wanted spares anyway for my THINK, I decided to get a couple modules, configure them for 48v & use them in my boat.
Retail price for the 2 Enerdel modules inside each THINK module is $1.3k for nom. 1.5kwh, which is quite expensive.
For $1.3k each, I bought 2 THINK modules (each includes 2 Enerdel 1.5kwh nom. 42v modules (48v fully charged)).
So for now I have a nom. 6kwh pack and will probably double that with another purchase in the next few months.
Hopefully these spares don't get bought up in the meantime…I really do want spares for my car and my boat.
Here's a pic of the 3kwh (nom. 42v @ 70ah) THINK module in my boat at this time (need to secure it, complete the wiring, get BMS boards wired to 12v, etc.):
Here's what an Enerdel module is like: http://liionbms.com/cgi-bin/moin.py/CustomProducts/EDI/EnerdelBattery
Again, the THINK module above includes 2 of these (on THINK City, they're wired in series---mine's wired in parallel above).

I picked up an escape hybrid pack for $350.00 after I had a bad experience with lead acid batteries.
it is 5.5Ah cells, total volts 325. = 1787.5watts i believe.
I guess I paid 195.80 per Kwh.
If you could direct me to your source for .40/ Kwh with BMS, I would be interested.

Hi Myles,
I'm not sure what "40c/kwh" is, but if it's 40 cents/kWh, then I wish had I that deal instead of the $418/kWh (without BMS) that I paid for my 180Ah CALBs!

"my only question on the ford escape cells is why use sanyo 5.5 ah cells when the tenergey ones are rated at 10 ah?"
Why stop there?
e.g. "why use 10ah Tenergy cells when you can use 17.5ah Enerdel cells"
Or, "why use 17.5ah Enerdel cells when you can buy a 35ah, 48v Enerdel module complete"
Or, "why use any of those cells when you can bet CALB 40ah or 100ah cells"
It's nice that we have lots of options with Lithium these days.
For about 40c/kwh (including BMS), my pack's Enerdel modules have some of the highest quality (and power) cells.
Better still, I don't have to mess with cells since the modules are already configured for 48v at the factory.
Had the deal with these modules not presented itself, I'd have likely gone with 100ah CALB cells.
But then, I don't know anything about these Tenergy or Sanyo cells.
Are folks going with them because of some good price point?
