    CALB cam

    Has anyone used these batteries before http://www.evwest.com/catalog/produc...roducts_id=301 they don't appear to exist on CALB's site and they seem to be considerably better than every other battery except the ones from new energy that I posted about before http://www.electriccarpartscompany.c...RGY_c_133.html which is suspect in my view.

    Does anyone have any experience with either of these batteries? Do they actually exist? Are they legit?

    Any info would be quite helpful.

    They are legit. EVTV tested them and they appear to meet their spec for discharge rates. They are very high energy density for LiFePO4, and discharge rate is respectable. There are cells with higher energy density and/or higher power - but generally more expensive to get both.

    Skip to about 1:00:00 for the test (be prepared for a lot of rambling and bumbling, but there is good info in there)

    Calb says they offer a "power" cell version and an "energy" cell version. They also showed a 25 amp hour cell which would be great for e-bikes.

    Maybe the energy cell is the 80Ah version Jack Rickard mentioned? [edit] Nope - these are the 80Ah, same discharge rates, slightly lower energy density. 246 Wh/L.


    Do you have a link to those? Can't find them on the CALB site.

    they looks a lot like the WINA batteries http://www.ev-power.eu/WINA-30Ah-100Ah/

    Quite an impressive volumetric energy density on these cells - 260 Wh/l
