Replacing an ebike battery usually comes down to voltage, capacity, and how the pack mounts to your bike. The four packs here are all HANIWINNER lithium-ion replacements, but they are not interchangeable: two are 48V 10Ah packs, one is a 48V pack with more capacity, and one is a 36V rear rack kit.
Quick take
If you ride a 48V folding-style bike, either 10Ah pack can be a direct starting point. If you want more capacity at 48V, the 13Ah pack is the middle option. If your bike runs on 36V and you can use a rear rack mount, the 20Ah rear rack battery kit gives you the largest capacity in this set.

Product notes
48V 10Ah Folding E bike Battery Replacement

This silver 48V 10Ah pack is listed at USD 188.99 and is the option whose title explicitly highlights folding ebike use. The listed model numbers include Samebike 20lvxd30, Samebike XWXL09, and Nakxus 20F063, so it is a reasonable match if your bike is in that family. The description also mentions an aluminum housing and BMS protection. The limitation is capacity: 10Ah is all this listing offers, and the other 48V 10Ah replacement in this guide carries a lower listed price. Choose this one if the folding-specific wording matters to you; otherwise, the lower-priced similar pack may be enough.
48V 10Ah E Bike Battery Replacement for NAKXUS / SAMEBIKE / KAISDA

At USD 179.26, this is the lowest listed price in the comparison. It still gives you a 48V 10Ah lithium-ion pack with the Samebike-family model numbers, but the title adds KAISDA to the NAKXUS and Samebike names. The shared details include a silver finish, lithium-ion chemistry, and BMS protection mentioned in the description. The limitation is that it is still a 10Ah pack, so it may not cover long-distance riding if your motor draws heavily. It is a sensible first choice when you want the most direct replacement at the lowest listed price in this four-pack set.
Battery 48V 13Ah Replacement for ENGWE / CMACEWHEEL

This middle-priced pack is listed at USD 207.99 and steps capacity up to 13Ah while staying on a 48V system. The title calls out ENGWE Ep-2 Pro and CMACEWHEEL RX20 folding bikes, and the attributes list universal bike-type compatibility. The description references a 30A BMS and notes that the 10Ah and 13Ah models have different dimensions, so this pack may take up a different space than a 10Ah replacement. That is the main limitation to weigh before buying, alongside the higher listed price than the two 10Ah options.
E Bike Battery 36V 20Ah Rear Rack Battery Kit

The highest listed price here is USD 359.98, and it buys the only 36V pack in the set. This rear rack battery kit offers 20Ah, which is the largest capacity listed, plus a BMS protective plate and an LED battery level indicator described in the listing. CE, RoHS, and MSDS certifications are listed as well. The limitation is system voltage: a 36V pack will not work on a 48V bike, and the rear rack form factor is different from the folding-bike packs above. If your bike uses 36V and has a rear rack, this is the option to consider.
Final recommendation by use case
- For a 48V 10Ah replacement at the lowest listed price: choose the 48V 10Ah NAKXUS / SAMEBIKE / KAISDA pack.
- For a 48V pack with 13Ah and a 30A BMS: the 48V 13Ah ENGWE / CMACEWHEEL replacement is the match.
- For a 36V rear rack battery with 20Ah: choose the E Bike Battery 36V 20Ah Rear Rack Battery Kit.
- If you prefer a 48V 10Ah pack whose title explicitly mentions folding ebike use and you are comfortable with its higher listed price: the 48V 10Ah Folding E bike Battery Replacement works as a Samebike-family option.
