Expensive and absolutely unusable, if I calculate correctly even with 176 Ah such a small charging voltage it is only 0.6424 kWh. With a classic 105Ah lead-acid battery with a voltage of 12Ah, the battery has an output of 1,26 kWh. I have photovoltaics and such batteries are useless.

You miscalculated. There are 16 units, that's for a voltage of 48v x 176ah, you have almost 8,5kwh, which at 80% utilization of the capacity you have over 6,7kwh of usable energy. And your 12v battery with 105ah has 1,26kwh, but it can be used at Max 50% if you have traction, that is, 0,6kwh can be used, which is about 9% of this.
