No addition fees for the battery for my bike 52v17.5Ah and I also bought a ebike kit for my wife's bike at the same time she got my old 48v11Ah battery. The shipping was free and there were no additional fee for any of it all bought during the virus at the end of April.offroadscholar wrote: ↑Tue Jun 30, 2020 2:52 pmDid you have to pay import tax on the battery ?beaker wrote: ↑Tue Jun 30, 2020 12:23 pmThey are usually li-ion 18650 cell that are just as problematic to have imported in sufficient quantities for an ebike and usually hard to source and expensive $5+ each. Companies who make lots of ebike batteries get them for less by buying 1000s at once. A person would also need a spot welder, pure nickel strips, battery case, BMS and the experience to make.whatwat wrote: ↑Tue Jun 30, 2020 11:51 amSorry, they are 18”.beaker wrote: ↑Tue Jun 30, 2020 11:11 amWhy would anyone want a 16" wheel ?
The biggest problem to overcome when selecting an ebike parts provider is getting a company that can and will ship the battery to Cambodia.
Beware many sell you a battery and kit only later to inform you that they can't ship the battery to Cambodia this has happened to me with several sellers.
There is only one company I have found they sell ebike kit and batteries my first batter had to be shipped to Vietnam then brought into the country by a very small courier company. The latest battery I got from them was sent by FedEX and the shipping was free.
There are also ebike parts suppliers in Thailand these days so when things open up again for travel one could go there to get a bike or parts and actually set eyes on the product you are buying. Thou flying back with a battery may be problematic some have said that putting them in carry on luggage was acceptable but not in luggage going into the planes hold. Returning by bus/taxi would be my choice to bring back the goods/ebike.
Compared to most electric scooters that’s a big wheel.
But as we are taking about E-bikes it’s a mute point. I looked on AliExpress and yes no batteries.
Aren’t they just the same as normal batteries just packaged up in a container?
My battery is 52v17.5Ah so takes 98 Samsung batteries @ $5 each so it would be $490 plus the shipping which is expensive because it is considered hazardous material so it was cheaper just to by completed battery with warranty for $600
I suspect in this time of Covid19 the GoC will be looking to maximum revenue where they can.

You must be a very young man indeed if you can wait for new technology like graphene batteries. Then there will be sodium-ion batteries, silica-based cathode for lithium-sulfur batteries, and batteries made of hollow nano-materials too but I can't hold my breath that long too old for that I want to ride now.whatwat wrote: ↑Tue Jun 30, 2020 3:16 pmGraphene anything is a long way off.Ravensnest wrote: ↑Tue Jun 30, 2020 12:46 pm Graphene batteries will change the whole e-bike industry and everything else that runs a battery.

Did you have to pay import tax on the battery ?

Good to hear.
On a side note, I'm looking at khmer24 and https://www.facebook.com/groups/2621016 ... __tn__=C-R for a donor Mtb.
There's seems to be a lot of Khmer privateers (ie not established bike shops) importing bikes . Wondering what the scam is.
Backdoor sales from the big bicycle factories near the Viet border ?

Some great used mountain bikes, I think they come from Japan, at great prices on Facebook.
