How much battery capacity should a boat have?
A proven rule of thumb is to have 3–4 times your daily energy consumption in battery capacity. That means that boats that consume 120Ah per day of energy should consider having 360–480Ah of capacity. This rule allows you to avoid damaging deep discharges, and it reduces your recharging time.
How do I choose a good battery size?
Proper battery sizing depends on several factors: how much electricity is needed to keep devices powered, how long those devices will rely on stored energy, and the actual capacity of each battery pack. The first step, and most important, is to calculate your energy load profile and estimate the usage required per day in kWh (Kilowatt-hours).
