I need to buy a new battery
Posted by Apprehensive-Spot199@reddit | ebikes | View on Reddit | 3 comments
My kickwey k7 Ebike, which has around 3000 miles, has significantly decreased battery life. I want to buy a new battery but cannot find it anymore. Can someone help me find it? It has the same battery as a thebbike called urbrica k7, it is 48v 23Ah, and the model is SY4824C01N

Yeah, I probably wouldn't build my own as I am inexperienced and even getting a built one is risky. It also is a little more common than you are saying (still pretty uncommon) but thank you for the suggestion, I will look for building my own last resort.

Good on you for recognizing risk! I’d still consider it rare because they don’t sell pre-built batteries of this casing on AliExpress. They sell another fuel tank battery type, but not the Aurora casing, which is really what you want.
Unfortunately, any of the pre-built Aurora casings I’ve found were either not 48v, super expensive, or from a site that would require you to buy a large quantity.
Another suggestion I have is to buy a Hailong Battery Mounting Plate, replace the current battery mounting plate on your bike with the Hailong one and wire the new mount into your controller (you would need a big Phillips head screwdriver to take out the mount, and you might need to take the seat off). If the battery mount fits in the frame, you can buy a 48v Hailong battery and insert it into your bike. The Hailong style batteries are a literal dime-a-dozen, so you can get a high capacity one for under $350. Just be sure you buy from a reputable battery manufacturer though. It should be a mod with minimal risk and will ensure that you can buy good battery replacements for your bike for a long time.
If you ever try that, please let me know! I only ride folding e-bikes and have only used Hailong Batteries as an after-market mod.

I don’t own the bike, so I can’t verify the battery type, but I’ve seen this case around as the “Aurora E-Bike battery case”.
It’s not a commonly sold battery type though, and most of the listings I’ve found seem to be of the actual battery case itself that someone would DIY an e-bike battery into. If you’re up for that or know someone who would build a battery for you, that’s not a bad option, but it will cost you a lot of money.
