lithium iron phosphate trolling motor batteries ?

Keep in mind the charging is different for Lithiums, and hard sudden draw (starting) can damage them for the long term from what I have read? Others on here may know more.

Most of the batteries have ratings for maximum continuous draw as well as peak or surge loads, often 3-30 seconds.  The 100 AH batteries usually can support 100 A continuous and surge about double that which should cover many starting applications.
