Finding a spare Li-ion battery 36v10.4ah

[georgebo2]

Where can I buy a second Li-ion battery 36v10.4ah in USA for a tricycle I purchased? The battery has a three prong power to the motor on the side. Ebay only sells this battery with the power on the bottom.

Unique connector design and case design are how manufacturers maximize their profit. If you want a spare or replacement battery, you have to buy it from the original manufacturer, at their sole source price.
Who you should contact for your spare battery.
Ebay vendors include some dodgy suppliers who change names if they rack up a bad rating. I bought a $300 pile of trash via ebay.

No question that OEMs like to gouge on these things, but there's more to it than that.

Proprietary connectors also reduce the chance that an unknowing user or unscrupulous builder will substitute a dangerous battery, BMS, or charger for the ones the OEM designed/vetted for the bike. Many if not most of NYC's messenger ebike fires come from just this scenario.

Yes, that reduces the OEM's product liability. But it also reduces your chance of burning down your house/building through a stupid mistake.

You want a Silverfish battery with side discharge like this one? They used to be common on ebay, and you can find them on the chinese aliexpress.com site, but I would suggest talking to FTH, a US seller. They may be chinese imported, but at least the seller is in the USA.

The other option, if your old battery is no longer god, is to convert the current mount to a bottom discharge Silverfish,

And if your battery isn't even a silverfish but some other weird form factor with side discharge, then never mind.

Anyone know if this battery would work? Also has anyone use this website?

You have not told anybody what brand bike you have bought. You haven't posted any picture of the battery nor the connector that it has. Litokala had some fans on parts & accessories thread, until they were caught using USPS to ship lithium batteries without hazardous content marking.

I brought this tricycle from Viribus and emailed them about a spare battery but never received any answer.

That battery looks like the battery harrys posted. I don't know how he guessed that, but props to him. So click the link he posted. Since the connector position is described, they must know about the other one.

The link Harry posted the battery is $320 and not sure if I can find that type any cheaper.

Real batteries cost that much and more. The one I ride that is 5 7/8 years old cost me $630. This was not patented, no special shape, had generic XT90 XT60 connectors. The bargains come from people that do not know how to weld, have no QA system, or are selling returned warranty failures.
