Brass bolt terminals have good conductivity and corrosion resistance, reducing voltage distortion and transmission losses
Brass copper material is more conductive than other materials. If your battery is lithium batteries, you must choose a brass terminal. It is better to keep the same metal for the cell plates and the terminals. But if your battery is lead-acid batteries, I would recommend you choose a lead terminal, because lead is more corrosion-resistant to sulfuric acid.
