277: Thursday 26th February 2015

Today I received new batteries. 38 x CALB 180Ah giving a 21.6kWh pack. I have ordered a JLD 404 to monitor the amp hours in and out and I need to send my charger back to have a new microprocessor put in so I can select Lithium. The microprocessor I have at the moment only has charging curves for Lead Acid batteries. I also need to make new racking, lots to do now.

  1. James,

    Pretty cool! Those batteries will turn you car into a real screamer. I couldn't believe the difference Lithium batteries made in my Fiero, I think the combination of less voltage sag and less weight will surprise you.

  3. They are the Better Place Packs that EVTV sold. That same cells that are in a Nissan Leaf. They charge to 4.2 volts per cell and the nominal voltage is 3.7 volts, a little higher than LiFePo4. I actually think your cells will have less voltage sag under acceleration that mine will. They are LiMn2O4 chemistry made in Japan, Automotive Energy Corporation.
