Hello John, Thanks for your response. Often L16's need to be used over T-105's at a certain price point to get more amp hour capacity with less parallel strings. That said, we have found that a properly sized battery bank with T-105's will typically last longer than a properly sized battery bank of L16's.
Could you comment on the build differences between the L16 and T-105 that might illustrate why this is? Jason Lerner Waldron Power and Light Co.
