The differences that matter
- Voltage, 12 V vs 24 V → the system decides: the two batteries cannot be swapped without modifying it.
- Capacity and current, 120 Ah and 120 A at 12 V vs 50 Ah and 50 A at 24 V → in theory about 1.4 kWh and 1.4 kW against about 1.2 kWh and 1.2 kW: energy and power are close, the currents are not.
- Cold-charge protection, yes vs no → in freezing weather only the 120 Dual is protected while charging.
Which one to choose
Choose ECTIVE LC 120 Dual 12V if…
your system is 12 V and you want a generous reserve in little space: 120 Ah is in theory about 1.4 kWh (voltage times capacity, no losses), in 10.2 kg and 31.5 × 17.5 × 19 cm, lighter than the other. You accept 2000 declared cycles instead of 4000.
Choose ECTIVE LC 50L BT 24V if…
your system is 24 V and you want Bluetooth control and an IP65 rating: 50 Ah is in theory about 1.2 kWh. You accept 50 A at most, no cold-charge protection and 12.3 kg.
