My first Ebike.

I recently bought a Goplus 36 volt 350 watt bike. I'm wondering where I can buy an extra battery for this. I've been checking the web with no luck. Can anyone help please.
 
Welcome to the site.
Contacting the original builder is sometimes an option.
The key to finding a second source for a battery is identifying what connector is on your bike. The dimension between the pins, the pin diameter, and a picture could help experts to identify it. Vernier or dial calipers are handy for this.
If the battery has a custom mount, and you wish to maintain that, then the original vendor is the only source likely. If you could hang a bottle or shark battery from your frame, then more options are available.
What country you live in will guide who are the most reliable generic battery vendors. In the US I've found a couple of pushers of ****, and one good vendor who was expensive but worth it.
 
See this thread about battery repair and repacking: https://electricbikereview.com/forums/threads/electric-bike-battery-repair-repacking.16033/
You have to be within driving distance of the repair facility in Denver or LA, because you are not an authorized hazardous material shipper.
If your battery connector is one of the common XT90 or ANDRSN type, then you could attach such a connector to a stick, mount it down in the tube, and run an extender harness to a shark or bottle battery hung on the frame. I would use insulating NEMA-CE material for this, formerly micarta/garolite/textolite, but some types of hardwood may be tough enough even under rain abuse.
OTOH, I converted my bike in the avitar for $830 of which $630 was a 50 mile capable 17.5 AH 48 v battery: seen encapsulated in plastic foam & aluminum on the front of the bike. I mounted it from the yubabikes breadbasket mounts.
 
I originally thought the battery was built into the seat tube, but this is what Google shows for the Goplus,

If you bought it on amazon, you will note that in the Q&A section, owners talk about buying an extra battery from the vendor.

It looks like a pretty common battery, sold on ebay and aliexpress, but there are probably some many variations of it, you should get it from your original seller.

Looks like a nice bike, congrats!

I agree with Harrys, get the battery from original seller. Then it should be plug and play.
 
Yes, looks like a nice bike. Where did you get it?

I would wrap a plastic bag around the LED control on the left side if the bike is parked in the rain. Might be good idea if caught riding in a storm too. Water gets inside any of these devices, the circuit boards will corrode. Circuit board inside the motor too, but you have to submerge it or pressure wash it to get water in it. That still happens to some people.

If you can't find that battery for sale from original seller, take it out and take a picture of it. Send that to battery sellers. GoPlus is likely one of many vendors putting their decals on a generic chinese bike. No one makes a battery case like that unless there's a big market for it.
 
One more question. The back wheel has a cap on the cable that goes to the motor. I take it that this pops off so you can take the wheel off to change the tire or what have you
 
Probably not. The cap is probably just to protect the wire and runs through the axle. The wire probably disconnects elsewhere on the bike. At least on my geared and direct drive hub bikes.
 
Have you found your spare battery source? Come to find out, a neighbor has been building and re-building batteries as a business for a year or more. I knew he had an e-bike but didn't know this till we saw each other recently. You might check with him. He's been into ebikes for quite a while, he might have or know where to get.

Any ideas
Many of the lower cost eBikes do not have a quick-disconnect for the rear hub motor...pictured below is the quick-disconnect on my rear hub motor

Your picture has camera shake, but I believe the rubber cap will come off and expose the hex nut that holds the axle. I also think there will be a connector plug further down the cable.

If there were no plug, there does not seem to be enough slack in the motor cable to allow the wheel to have the wheel installed. The wheel has to drop 14"-16" to clear the frame. That requires about a foot of more of slack.

Here's a brightened up GoPlus picture. Also showing a picture of one of my ebikes that shows the connector.
