Subject: Re: [Electric Boats] Battery specific energy and power in relation to volume and density
Light catamarans come in many sizes? Is your 14 feet or 40 feet long? Sailing or not?
2kW sounds small for a battery pack used for propulsion, unless your cat is also small. Or is this a house battery?
Lithium doesn't like to be fully charged all the time, but there are different ways to deal with it. Set your charger to stop at 80%, or slow the charge rage.
Lithium is probably the lightest battery formulation you will find. Depending on the size of your boat, your battery's weight may be a significant factor.
For example, my former lead acid battery was more than 10% of the total weight of my boat. My new LFP battery (larger capacity) is about 5%.
