This Video is our 15 ton Lithium Battery locomotive for the China Railyway group, and they used this locomotive on tunnel construction.
The Reason why choose the lithium battery as the locomotive power supply is that the battery has the advantages of quick charging, matain-free and long service life.
Usually, the service life of the lithium battery could up to 5-8 years, which is 5 times more than the lead-acid battery. It doesn't need to add the bath solution, which is labor-saving.
