Do you know that LiFePO4 cells are the same price (in Europe), longer-lasting, lighter and safer than traction lead-acid ones? They pretty much have no disadvantages to lead-acid, and the need of a BMS (and heater if needing to charge below freezing or run below -4 °F/-20 °C) is no problem since those are a fraction of the cells’ price. The only reason I see behind this move would be acute lithium shortage in China.
