Battery Configuration

House, engine, emergency parallel and thruster switches are located in the mid-berth. Inverter battery switch, Automatic Charging Relays (ACR), and House circuit breaker are located in the port-side lazarette. Thruster Battery Switch and Thruster ANL Fuse are located in the starboard-side lazarette.

Standard: 2 house batteries (320A/h Lead Acid), 1 engine & 1 thruster battery (Group 27 Deep Cycle). ACR #2 is connected to the House batteries. ACR #1 is connected to the Engine and Thruster batteries.

Lithium Upgrade: – 2 (300A/h Lithium) total lithium house batteries, 1 engine & 1 thruster battery (Group 27 Deep Cycle). ACR #2 is not present on the lithium upgrade. ACR #1 is connected to the Engine and Thruster batteries.

Due to supplier shortages, some versions of the C-248 Coupe may have 6 100A/h lithium house batteries instead of two 320A/h lithium house batteries. This configuration has the house batteries split up (3 on the port-side lazarette, 3 on the starboard-side lazarette).

*The EMERGENCY PARALLEL switch is used in the event that the engine battery drops below the level of charge necessary to start the engine. Use only for EMERGENCY starting of the engine. Once the engine is running, turn the EMERGENCY PARALLEL switch to the OFF position.
