Questions and answers
Adding extra 12volt DC to DC charging So would that be connected directly to the 100 amp/hr leisure battery ? If not where to connect ?
To connect a 12V DC to DC charger to a Sargent EC328 leisure battery system:
1. Disconnect Power: Turn off the EC328 charger switch and disconnect the 230V mains supply.
2. Battery Access: Locate the leisure batteries, which may be connected in parallel. Ensure both batteries are identical if there are two.
3. Inline Fuse: Ensure an inline fuse (max 20A per battery, total not exceeding 40A) is fitted between the battery and the electrical harness.
4. Charger Connection:
- Connect the output of the DC to DC charger to the leisure battery terminals.
- Observe correct polarity: red to positive (+), black to negative (−).
- Do not use crocodile clips; use secure, bolted connections.
5. Safety: Ensure no flames or sparks near the battery, as explosive gases may be present.
6. Operation: Once connected, the charger will supply power based on load priority. The EC328 system allows up to 25A (300W) for leisure equipment, with remaining current going to battery charging.
This setup ensures the DC to DC charger works properly with the EC328 battery system.
