Default Cardboard battery mockups

Took a cardboard box and made 3 battery sized boxes (I'm planning 4). Headed out to coach this weekend for a different project & will "play" with them to figure out best placement before I order. It's amazing that 800 Ah (over 600Ah usable) and 1016 kWh of capacity can be packed into such a small package that weighs only 220 lbs! Obtaining 600 Ah of usable juice from 4d's would require 6 at a 50% depth of discharge and approx 700 lbs!

Model GBS-LFMP200AH - http://elitepowersolutions.com/produ...roducts_id=149
- Nominal Voltage: 12.8V (4X 3.2 V)
- Nominal Capacity: 200 Ah
- LiFeMnPO4 chemistry
- Operation Voltage Range: 11.2 to 14.4V
- Weight: 24.9 kg or 55.0 lbs
- Dimension: 500 X 259 X 142 mm or 19.25 X 10.2 X 5.5 in
- Max Charging Current: 3C
- Max Discharge Current: 3C (continuous) / 10C (pulsed)
- Cycle Life : >2000 (80%DOD)
- Operating Temperature: -20 to 65 C or -4 to 149 F
- Self Discharge Rate: <3% monthly

These are the same cells from Elite that Nina & Paul installed and they're big brothers of the ones I put in my scooter 4 years ago. Called Elite today and their tech answered right away. As others have mentioned, Balqon's are slightly cheaper but it's next to impossible to get support from them . Being able to immediately speak with an exceedingly patient tech on a project like this can be a lifesaver!
