I have bought batteries from ctechi several times, and their sales are very professional, and they will reply to my questions quickly; I encountered two small problems, and they quickly solved them for me.And most importantly, the batteries are of the best quality. No mechanical issues. Not only flexible busbars were delivered, but also foam sheets which can be packed between the cells. I would do my next order here again with a good feeling.

I highly recommend this seller. They are a reliable supplier, quick to find solutions and offer advantageous alternatives for the buyer. Fast delivery adds to the overall positive experience.
