I bought 21700 5000A *h Tesla batteries (gray) individually for my electric bike, the owner Maxim personally advised me, I also needed nickel plates and round adhesive insulators on the ends of the batteries, which were not sold, but were in the battery workshop, but Maxim met the customer halfway and sold what I needed Thank you for diplomacy and compromise, which are very lacking in our country and in the world nowadays
I bought a bicycle kit from them, the specialist consulted and selected it for my needs. I was pleased with the price and the large assortment available. I can safely recommend it.
I can't say specifically about the quality of the product, but I ordered the product twice, a motor wheel, and twice it wasn't delivered on the appointed day. They're making up excuses. They do not fulfill their obligations regarding the delivery time. If you want to waste your time, use the store's services.
