House banks more than bow motors
Battle Born is often used as a house-bank lithium on boats that keep a separate lead-acid starter. Parallel rules, bus bars, and a charger that can be set for LiFePO4 still matter. A tray that physically accepts the module is step one, not the whole job.
Float and the charger
Lead-acid chargers that hold a float voltage will keep a lithium pack sitting at a voltage it does not want. Battery University is explicit: LiFePO4 does not use a conventional float, and float shortens life. If the slip charger cannot be reprogrammed, the charger is part of the visit.
Charger program on the visit
A Battle Born house bank needs a charger that can be set for LiFePO4 and that will stop at full. We read that charger with the module. Parallel cables and bus bars are part of the same visit when more than one module shares the bank.
Lines we are asked about
Model names below are public line names used to identify batteries already on boats.
- 12-volt house modules — Deep-cycle LiFePO4 modules used in 12-volt house banks, sometimes paralleled.
- Heated options — Some lithium lines offer internal heating; still confirm whether a given module includes it.
We replace marine batteries at the boat. See services and what changes a quote.
