This is a thread started for 7Circle.

I have some saved cash .. and before I waste it I want to buy some good batteries.
Not second hand used one's.
So for $5000 what cells would be good.
But I need a BMS and 6hr charger (C/6).
So what would allow me 195 kW peak (10sec)
And 95W continuous.
EIG SOUND popular for power applications.
Need to do more study.
$1/wh would give me 5000 W.h
50 kW cruise power at 100km/h.
5000/50000 = 0.1hour 6min
10KW at 40km/h gives 30min
Or 20km
So 200 kW peak 5 kW.h 40C rate discharge.
50kW is 10C
10kW is 2C
There are some dream targets of midnight persuasion.
I hope in 2015 they are achievable.
Cheers 7c

$5k maybe less
For plugin hybrid conversion.
So the short answer is NO but the long answer is YES.

103.5kg
8640Wh
~25kW continuous
~50kW peak?!?
So the short answer is NO but the long answer is YES.

40 x leaf modules
$5k ish
152kg
20'000Wh
30kw continuous (probably)
150kw peak (10 sec, claimed)
pushing all the above cells that hard won't lead to overly good service life to be honest

I agree but it wasn't part of the technical specs
