Battery capacity on the label is not usable capacity. Chemistry drives depth of discharge, charge acceptance, and cold-temperature behavior. This hub covers how to size a bank for real loads and what changes when you move from AGM to lithium.

What this hub will cover
Guides are published as they clear research and editorial review. Every commercial page cites primary sources for its electrical figures before it goes live, which means this list fills in deliberately rather than all at once.
- Lithium vs AGM for RV use
- How many amp hours do I need
- Usable capacity and depth of discharge
- Cold weather charging limits on LiFePO4
- Converter and alternator compatibility
Before you act on any figure
Electrical specifications are model-specific. Confirm every number against the manual for your exact equipment, and treat wire gauge, fuse sizing, and breaker sizing as safety items. When our recommendation differs from your manufacturer's requirement, follow the manufacturer.
