I'm upgrading my Sea Ark with a 2019 DF4 175 Suzuki to Lithiums . Was told by amped outdoors that I shouldn't us a Lithiumn for a starter battery as it's not reccomended by manufactuer. Got a 36 volt to replace the 3 wet cells and a 100 amp hour to run all the electronics but left one of the wet cells per there advice. Really would like to get rid of that battery but concerned since motor is still under warranty. Advice? Scott
