In June 2018, we received an inquiry about Hailong model from Antoine. In the inquiry, he said in addition to the batteries and chargers, he also wanted to order the controllers and install the controller in the battery rack. He has a shop in France, and help the customers modify the normal bike into electric bike. We are the manufacturer of lithium battery, but if the customers prefer us purchase the other things for them, we will try our best to hep them. So we found a controller factory that we have cooperated before, and send the request of the controller to the factory. After the controller parameters were confirmed, we send the prices for the batteries and controllers to Antoine, he was satisfied with the prices,and placed a sample order. Then we arranged the batteries production, chargers and controllers purchase. When the batteries passed our factory test, we sent the goods to Antoine.
Unfortunately, due to the violent shipping by courier, when Antoine received the goods, one battery case was damaged. This is the first time that we have encountered damage to the goods caused by transportation. The battery could work, just the case is broken. At first we want to send the empty case to Antoine, but he said he don’t know how to change the case. So we decided to send the whole battery to him. Then we immediately arranged to re-produce the batteries and strengthen the package of the goods before sending them to Antoine. After that, he received the perfect goods. Probably because of our good products, good service and after-sales, Antoine continued to place the orders to us.
First we received an inquiry about the water bottle battery from the Poland customer. The request of the battery is 36v 11.6Ah battery with Panasonic cells. We asked the customer more details about the battery that him wanted. He said he want 5 pcs as first order for sample testing. After passing the testing, he will order more. The customer wanted to order the battery with charger, we can provide the charger, too. So we send the quotation of the battery with charger to him.The customer checked the price, and he said the price is ok. Then we made the PI for the customer, he arranged the payment. We checked the details of the battery, asked him the motor power for this battery.
Because we need make the battery fitted with the motor power, or the battery can’t work. In generally, this kind of battery is assembled on the electric bike, the least motor power is 250W. What surprised us is that the motor power is 60W. And he send the picture of the application. This battery is for lighting.It is very smart, when using this battery, they can take the light everywhere. It can be assembled on the wall or just leave it on the ground. It is very convenient. After confirming the details about the sample order, we started the production. The customer was very satisfied with the sample testing, then he placed the bulk order. Now we are having monthly orders from this customer.
