48V Lithium Ebike Battery, 12Ah/20Ah, w/ 30A BMS, for Electric Bicycles & E-Motorcycles(100W-1500W), Includes 2A Charger XT60 Connector and Base (48V12AH (with Charger))

I’ve only had it for about a week. Paired with a Bafang BBS02 and it meets my expectations so far. Battery life seems reasonable for what it is, but this is my first e-bike and I don’t really have enough perspective to know how it compares. It’s a cheap battery and it works. I am considering adding a BBS02 to another bike and will most likely purchase again for that bike.

I seems to be a good battery, I am still in the process of building the bike and have not used this battery.

I purchased this item for my e-bike. Initially, I encountered an issue with the internal connection at the base, which required repair. Furthermore, the battery life was insufficient, as it depleted after a single ten-mile trip, necessitating a recharge. However, the customer service team has successfully resolved my concerns.

Battery quality seems to be great. The charger it comes with is able to tell when the battery is full and stop charging (though you should still unplug it instead of leaving it at full while plugged in, as with any battery). Very simple to install and I feel it did a good job for the price. Very functional

I ordered the 48V 12AH battery. I charged overnight to allow the battery to charge to full and the BMS (battery management system) to balance the cells. I discharged the battery at 0.6A to measure the capacity and the capacity I received was 8.7AH which is only 72.5% of the advertised capacity.

got it to replace my dads ebike battery took it apart found his controller was built into the battery mount after getting this unit i took base apart founds it had just enough space to fit his controller had to solder the new end onto the controller but in the end it fit and works

While the battery accepted a charge and seems to function OK on the bike, I was disappointed with the poor quality control of the battery and components. One of the three screws which secures the cover on the bracket was cross-threaded. The mounting bracket is setup for strain relief of the two conductors which connect the battery to the bike, but neither the two screws nor the strap were included with the bracket. The AC cord for the charger was not secured to the charger body.

Item worked as described and it was good quality
