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.

Worked out great for my dead hoverboard. Now I can ride my hoverboard 10 miles with the go cart attachment. We'll worth it.

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

Battery holds up very well so far.

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.

After getting my first ebike and putting a couple hundred miles on it, I wanted a spare and bigger battery than the factory supplied 12 amp pack. I shopped around quite a bit, planning on something which could be moved to a project bike in the future. I built that project bike using this 20 amp battery to power a 1500w peak font hub motor which is not hooked to the PAS system. At 65 years old, I don't care to pedal as much as in my younger years. This 20 amp battery powers close to 75% of all the power used on my rides, which are rarely less than 10-20 miles. I have had no problems with this battery in 4 months of what some may consider moderate to heavy use. It charges consistently, and as long as it is not in the red, it responds as if it's fully charged. I will probably eventually get another of this exact battery in the future.
