36V 48V 60V Ebike Battery 10AH 12AH 16AH 20AH 25AH 30AH 40AH 50AH 60AH Lithium LiFePO4 Battery Pack with 3A/5A Fast Charger and 20A/40A/50A BMS fit for 3000W-250W Motor

The hate BTR gets online had me worried at first when I learned of the bad reputation prior to ordering. My battery is the 48v 20ah lifepo4. To my surprise, this battery is serving me very well. I can’t speak on their lipo batteries, but I would by their lifepo4 again. The listings now says 40 amp bms. When I bought mine it said the 48v 20ah had a 50 amp. I am running mine with a fardriver controller and I have only had it cut out try to run 90 amp and over. At 70-80 amps it runs like a champ. I don’t drive long periods at top speed mind you. I have to wait up for my kids frequently, so ymmw. Either way, the high amps is on take off anyway so I don’t see maintaining high speed as an issue because it won’t pull full amps. Battery life seems legit. My sons 16ah dies while mine has plenty left in the tanks and I am 295. So I’m all. Great battery.

I got this into the bottom battery tray of my MX500. I cut the lip of the front end of the tray because otherwise the battery is a half inch to long, although you could just rest the front end of the battery on the edge of the tray. I put the controller in the top battery tray. I reused parts of the original battery harness and fuse, but hooked the new charger connector directly to the charge wires on the battery. It's got great range and power.

Used the battery on a Razor MX650.Due to 2022 shipping delays, the seller's large battery shipment took over a month to arrive in order to replenish his inventory; however, the seller's communication was great during the delay, and he offered a discount due to the delay.Once the seller's battery shipment arrived, the shipment to my house was fast. Connected battery and everything worked great. Seller was very helpful with additional correspondence about how to connect the battery and charging port.Highly recommend the seller and his LiFePO4 batteries.

Let me just start out by saying I had purchased my first BTR battery roughly a year and a half ago and roughly 6 to 8 months in had a BMS issue okay they sent me a new battery I was thrilled, on the flip side it was a different style battery using battery cells instead of the packets and secondly the original battery I had opened to figure out what was wrong with it because it was still holding a charge but it wasn't allowing anything to go through it when I throttle all my scooter and found out that instead of having a 50 amp BMS it had a 30 so I would beware that if you're looking for certain current draw not to go with this company because hey they stand behind their batteries but b they don't exactly say what's in them because I've used the same controller with the same setup and this is the second battery in the same time frame that has gone bad so either they're using cheaper ones with bigger capacitors for somehow him hauling it to work at 50 amp but it's definitely says straight on the old one that I open it's 30 amp and I'm kind of taking back by that considering I spent over $300 for the battery.

Was able to ride over 25 miles on first charge.A substantial increase in miles over the SLA batteries I was using.The new batteries charge faster than the old SLA batteries.Will buy again from them when I need a 48v battery for a different bike.Customer service response was fast.

I’ve used it for a few weeks now and it’s still going strong. I gone 10 miles and the battery meter still on full and still moves my scooter at full power. The old lead batteries lasted only 9 miles with a noticeable drop in power at 6 miles. The lead acid batteries were also much heavier.

Changed out the kids 36v atv batteries with this and the ride time went from 30 mins to hours, honestly, the kid gets tired of riding before the battery dies.

Pulled SLA batts out of modded Razor MX500 and added 36v 20ah. First battery I received was defective and they immediately sent another. I now need to get one of their 48V for another bike.
