Victron 12-165 GEL (24V Bank)

• Type: 12V 165Ah GEL (VRLA), configured as 24V bank
• Use: Legacy/aux battery bank for 24V systems

Installed

• Quantity: 4 units installed
• Bank arrangement: 2S2P (two series pairs in parallel, 24V nominal)

Configuration Notes

• Two 12V 165Ah GEL batteries in series for 24V nominal, with two such series strings in parallel (2S2P).
• Observe Victron recommended charge voltages for GEL chemistry.
• Ensure temperature-compensated charging if available.

Capacity

• Per battery: 12V × 165Ah = 1,980Wh (1.98kWh)
• Bank topology: 2S2P → 24V nominal, Ah sums in parallel: 165Ah × 2 = 330Ah
• Total energy (theoretical): 24V × 330Ah = 7,920Wh (7.92kWh)
• Usable energy (typical guidance for GEL):
• 50% DoD (long life): ≈ 3.96kWh
• 80% DoD (shorter life): ≈ 6.34kWh
