On a fishing boat or a small workboat out of Hout Bay, Kalk Bay or another South African harbour, the house bank works every day: electronics, lights, maybe a small fridge or a washdown pump, often in salt air and with long idle days between trips. Yards and dealers look for a LiFePO4 battery for fishing boats in South Africa in 12.8 V or 25.6 V that can replace the lead-acid house set, with the starter battery kept separate. This is not a load-shedding page for a house or shop, and it is not a general supplier landing.
LJY Energy is a LiFePO4 supplier and OEM/ODM coordinator in Shenzhen; we are not a factory. We supply 12.8 V 100, 200 and 300 Ah deep-cycle modules and 25.6 V options, and we confirm the charge window and the enclosure in writing. Fitting on the boat, and any local approval, stay with the yard.

House-bank modules
| Module | Nominal energy | When it fits |
|---|---|---|
| 12.8 V 200 Ah | 2.56 kWh | a typical 12 V house bank on a small workboat |
| 12.8 V 100 / 300 Ah | 1.28 / 3.84 kWh | shorter or longer trips on the same 12 V bus |
| 25.6 V 200 Ah | 5.12 kWh | native 24 V house bank; usually preferable to two 12 V modules in series |
| Starter battery | kept separate | lead-acid or a LiFePO4 starter, with a DC-DC charger or isolator; never in parallel with the house LiFePO4 bank |
Energy = nominal voltage × Ah. A native 24 V (25.6 V) bank is usually cleaner than two 12 V modules in series. LJY does not claim a marine classification-society certificate, and it does not claim an NRCS or other South African product mark on this page.
What the yard should close
- House loads and the days or hours of autonomy between charges, including idle days at the mooring.
- Keep the starter battery separate; charge the house bank from the alternator through a DC-DC charger so the alternator is not overloaded.
- Charger profile 14.2–14.6 V per 12 V nominal; equalisation pulses of 15.3–15.8 V are not used on LiFePO4.
- Moisture, salt air and the compartment: enclosure and ingress rating are confirmed per project.
- Documents: a UN38.3 summary and SDS come with the quotation. A class-society certificate or an NRCS mark, if a buyer asks for one, is confirmed per order or is not available; nothing of that kind is claimed here.
For yards and dealers with several boats
The same house-bank model, repeated across a harbour fleet, simplifies spares and chargers. After the first confirmed fit-out, later orders repeat the layout. Figures for price and timing are reserved for the formal quote.

How we proceed
Loads, voltage, compartment and charging sources → quotation → first boat → later orders. Prices and lead times only in the quotation.
