The e-cart / Balkancar manufactured in Bulgaria in the 1960s-1970s is an electric cart that has been exported to many countries. The drive was powered by a large lead-acid battery located under the cargo bed. A filling / charging was usually enough for the whole day. Overnight, he was then recharged on the network. The E-carts are very sturdy and could last up to 30 years in use, a good construction that is still built today.
