Add up your daily draw
List every load in amp-hours per day, then size the bank to cover it with headroom.
Halve the lead-acid number
Lithium gives full usable capacity, so a 100Ah lithium replaces roughly a 200Ah lead-acid bank.
Match the charge source
Converter, alternator or solar controller all need a LiFePO4 profile.
