That’s pricey per kWh - lithium tech generally is. I’ve just installed an off-grid solar system, and ended up putting together a spreadsheet of a whole bunch of battery options, got prices per kWh, and then built in a factor for lifetime/max cycles.

Ignoring max cycles, the cheapest lead acid I found was £87/kWh. Lifetime was poor, however.

The best bang for buck was OPzS lead acid cells - £115 per kWh, and a long, long lifetime and high cycle count. They’re the most commonly used cell in new grid-scale solar installs, and it turns out there’s a reason for that - over 15 years, they cost less than 20% of lithium over the same period.
