We have the pleasure to introduce our company as "ZHEJIANG BINGO TOOLS CO., LTD, involved in the field of battery power station and battery operated welder to construction, Metal & Engineering Industries and Oil industries sectors. Since year of 2015, after carefully study from abroad brand Fronius, we successfully developed the first battery operated welder in China, built in battery design, capacity around 300Wh. Limited by the cost of Lithium-ion battery cell at that time, sales volume of the first generation was not satisfying. Until year of 2017, after continuous testing, we found the suitable supplier of Lithium-ion battery cells, CATL, they are battery supplier for BMW, VOLKSWAGON, TOYOTA, VOLVO, JAGUAR.
