Dont worry about number of cycles in life of Lithium battery:
- One Cycle is contiguous use to 100% battery capacity.
- Lets assume boat use every weekend of a year. That is 50 cycles a year if battery is used 100% on weekend.
- Target battery has 1500 cycle life. That’s 30 years at 50 a year. Your kids will inherit the battery.
