Hi
Looking for my 144 volt 28.8 kw battery pack I stumbled upon this 4.4 ah 36 volt lg mf1 pack
http://www.ebay.com/itm/201916138726
Here's a spec sheet on the cells:

This guy tested the pack and the bms that comes with it

So i figure a 4s45p would give a nice 200 A 144 volt pack @ approx 180 kg.
Much lighter way cheaper than lifepo4 especially as a bms is included.
Also it seems the pack can be hooked to a charger, while discharging

Series hybrid anyone?
I wonder, since lithium batteries do not balance in series but will in parallel (or am i wrong), this should perform better than a lifepo4 pack, which could be 45s2p with 100 ah battery. With the lifepo4 pack one dead cell drops out 50 % of the pack. Where in the other case just a bit over 2% would drop out. So still alot of range left in that case.
But at the price of less cycles (500) and a less safe chemistry?
What do you think. Anyone using these?
