Great to hear the battery is still going strong!
Our batteries are more expensive than generic Chinese cells and should last if properly looked after for many, many years, especially our latest big Samsung batteries with all the clever software. Our small battery is now £299.00 so pretty good value considering there is dealer margin involved and a solid 2year warranty.
If anyone is considering importing batteries from China, you should be paying 6% duty and 20% VAT plus documentation charges when the battery lands in the UK. It is not a great idea to evade paying the tax man!
WARNING
Most importantly, anyone importing batteries must make absolutely certain they have the correct certification and that they are insured against any damages caused if the battery being imported over heats and catches fire after it has entered European territory. The importer is 100% responsible for any damages a faulty battery causes inside Europe. Imagine if the battery overheated in the ship and destroyed the contents of the container, or worse. The importer is responsible. If a faulty battery causes a house fire in the UK, insurers will ask to see certification. If it is not available, the insurers would probably kick the claim out. If however you buy a battery from a business in the UK they are the importer and are responsible for ensuring the correct certification is in place.
If the batteries are are shipped by air (if they arrive in anything less than 5 weeks they will have been), the transport is completely illegal. This would mean that the Chinese battery seller has falsified the paperwork and declared the battery is under 100Wh. The IMPORTER would be found responsible if the falsified records were discovered in the UK. This is a criminal offence.
Passenger and cargo flights will not accept any lithium battery over 100Wh even if it is connected to the bike. We can all imagine the consequences if a battery overheated and caught fire mid flight. The IMPORTER of the battery would be held responsible.
The cheaper prices available from unscrupulous sellers on EBay may seem great value but please consider carefully before buying and ask to see the current certification, which to be legal must be under 12 months old. Make absolutely certain the battery is being declared properly to the shipper, if they are flying the battery they are falsifying the documentation.
Also consider proper battery certification costs $4,000.00 per battery size per year. We pay $8,000 per year for the certification of two batteries. A lot of these cheap battery sellers will not have spent the money getting batteries properly certified, the importer has the responsibility to ensure the correct certification is in place.
Sorry to sound doom and gloom but if you are buying batteries from China you are the importer and responsible.
