Sample is available. You can pay the sample fee by Paypal or Western Union.Once the bluk order happened, we will pay back the sample fee to you.
Normally we send sample by UPS, FEDEX and so on. But it is battery built-in product, someplace it may be some difficult to ship to by air. Some places like these we normally suggest shipped by sea for test small order.
For samples, 15 days we can arrange the shipment.For bulk order like50-200pcs, we can finish it with 45 days, if for 200-1000pcs, we can finish it within 60days.
Yes, we can offer all Customs clearance documents.Such as CO, FORMA, FORM E and so on.
Yes, we can offer CE for ebike, CE for battery and Adapter. Besides, we can also offer EMC, LVD for adapater and UN38.3 for battery.
Keep your bicycle in a dry location away from the weather and the sun. Direct sunlight may causepaint to fade or rubber and plastic parts to crack. Before storing your bicycle for a long period oftime, clean and lubricate all components and wax the frame.Deflate the tires to half pressure and hang the bicycle off the ground. Don’t cover with plastic as “sweating” will result which many cause resulting. Please notice that your bicycle warranty does not cover paint damage, rust,corrosion, dry rot or theft.
It is advisable that the following steps be taken to prepare for and help prevent possible theft.
A.Maintain a record of the bicycle’s serial number, generally located on the frame underneath the bottom bracket or on the head tube.
B.Register the bicycle with the local police.
C.Invest in a high quality bicycle lock that will resist hack saws and bolt cutters. Always lock your bicycle to an immovable object if it is left unattended.
Yes, you should charge the batteries fully before first using them.
Yes, the batteries will need to have a “break-in” cycle consisting of ~ three discharge/charge cycles before they will reach optimum performance. This involves three complete discharge and three complete recharges. After this initial “break-in” cycle the batteries will have maximum possible performance and less line voltage fluctuations under load.
All the batteries will self-discharge when not in use. The self-discharging rate depends on the temperature at which they are stored. Excessively cold or hot storage temperatures will drain the batteries faster than normal. Ideally the batteries should be stored at room temperature.
Batteries naturally loose their charge over time. To keep the batteries in optimal condition and extend their life. It’s recommended that a top-off recharge be performed at least every 90 days.
If you have left the power switch on or your product has not been charged for a long period of time, the batteries may reach a stage at which it will no longer hold a charge.
No,once the batteries are fully charged(as indicated by the light on the charger) it is best to unplug them from the charger. Leaving the batteries charging longer than necessary is called “overcharging” and will not increase performance. Currie-supplied chargers are designed to avoid over-charging a battery. Still we recommend that you always unplug a charger after the unit is fully charged to avoid the possibility of unanticipated circumstances such as an unexpected power surge from a lighting strike (or other power line anomaly) protentially causing damage. Only use Currie-supplied chargers.
Yes,it is normal that the batteries will become warm to the touch during the recharging process. This is because the increase of the internal resistance and less energy conversion efficiency from electric energy to chemical energy.
Average battery life depends on use and conditions. Even with proper care, rechargeable batteries does not last forever.
