Thinking of going to a Lithium Iron Prosphate (LiFePO4) Battery

[mcspeed]

"Without the maintainer in the off season (which is short here in TX) the battery would fully discharge and die in a year."
But this would be true regardless of the battery type..........

True however lipo has bms which better protects the battery from total discharge unlike LA which will go totally dead and do damage. In this situation lipo has an advantage but I don’t think it is worth the extra cost due to the harsh environment annd the following….. lipo will not get a full charge from a LA designed charging system. Internal cells never get balanced and shorten the life. Just some well know differences in battery chemistry.
