[QUOTE="AlanT, post: 499386, member: 30185"] Approximately twice the storage capacity assuming a lead acid Depth of Discharge (DOD) is 50% and LifePO4 lithium DOD is 100%. But as mentioned there are other factors. Lead acid will deliver less power (voltage and current) as it discharges. And I wouldn't run a lithium to 100% discharge despite the specs. A claim of twice the power may be some marketing "puffery". One thing to consider is matching your TM max amperage to the battery you select. For example, a 12V 40ah lithium [I][B]may [/B][/I]have a maximum discharge current of 40 amps. It may be higher for short bursts (5 to 30 seconds). Some Minn Kota 55# thrust TMs will draw 50 amps at wide open throttle. Over drawing your lithium battery could result in damage to the battery or TM, so match the specs. The world gets more complicated every day. Good luck and have fun. [/QUOTE]
