48V 20Ah Ebike Battery 48 Volt Lithium Battery for E Bike Electric Bicycle with 30A BMS 54.6V 3A Charger

Works well. It has lasted months now with many charges. Easy swap on my bolt pro e bike

I used this item in a DIY boombox project. It powers a 12-36 volt chip amplifier; this battery has a maximum charge of slightly over 40 volts, and the 36-volt amplifier seems to handle it well with ample runtime. I am very pleased with the product's quality, although it is rather expensive. I was disappointed by the lack of detailed technical specifications, especially considering the price. It felt like a risky purchase without more information; however, a quick message to the seller provided the answers I needed. I believe sharing the specifications I received would be helpful to others. The cutoff voltage is 25V. Recharging is recommended when the voltage drops below 30V, and it is safe to allow the BMS to cut off the output at 25 volts before recharging. Additionally, I was pleased to see that it came with a connector with stripped bare ends to wire to whatever you needed, meaning there was no need to order an additional connector or cut the factory connection to make bare wires, especially considering how unsafe that would be with a battery of this size.

It showed up fairly quick. Does everything I needed to do, I’ve used it with a couple of different projects now.

Battery holds up very well so far.

I actually ordered the wrong battery for my ebike it won't work with it. But I'll keep the battery for now

These worked perfectly fine while the project they were in ran. Broke that, but these held up. Too bad they're only good for about 720 watts each.

Battery seems like it decent quality. I will update as time goes by. "Charger" has a little fan in it which is nice because these high amp PSUs get hot. I'm mostly writing a review already because I was so excited to see they included the other end of the xt60 connector with leads attached to it. I thought maybe I was gonna have to order one or cut the other one off the battery and wire it directly to the controller, nope, they through one in the box for me (: I love it! So I wired that to the controller, now I can unplug the battery from my build if I need to. UPDATE: BATTERY WILL NOT CHARGE ANYMORE. Either a connection broke inside the battey or the BMS blew. Only had the battery a few month and used it o ly a few times. I'm trying to eventually sell my builds so this is absolutely unacceptable. Probably going to start building my own packs I think.

I can get about 20 miles out of this battery on my E bike if I pedal a lot
