    In looking at LifeBlue's website, it appears that their 200AH, and 300AH batteries both have the same specs:

    Discharge Current: 150A continuous, 200A for 30 Minutes, 300A for 3 seconds

    What gives?

    Also I'm curious about which Charge Controller is supplied in the package.  Is a MPPT or is it still a ZAMP PWM? They don't mention a shunt so it may only be a Zamp model. Since Lithium batteries needs to be charged at a constant 14.6 volts and I'm wary of the Zamp ZS-30A / ZS-40A controllers as their Absorption charging voltage is preset to 14.4 +/-0.2 VDC for LiFePO4 batteries.

    If I'm reading something incorrect in all this, please enlighten me.

    According to LifeBlue, the discharge current is the same between the 200AH and 300AH models, and is correctly listed.  The difference is the storage capacity, i.e. amp-hours — 200 for the first and 300 for the second.
