This indicates the battery is fully charged.Charger when connected to the battery measures at 54.6V.Contacted the seller. They asked me to do voltage measurement at different points. Did all and Emailed info back to the seller.They like me to do more diagnostic/trouble shooting for them.I am not really an eBike mechanic.When I bought the battery did not anticipate having to trouble shoot the new item and report back to the seller.What if you bought a new car, and the car stopped running after a few miles?Is this a good sign?Are you supposed to run diagnostics and report back to the dealership mechanics?Charger LED! failedBattery is loosing power after fully charged.I ended up pedaling home a 75 pounds eBike.Your be the judge.Alex, Southern CA==========================================================================Received battery in 4 days by Fed-Ex.

I have a DIY e-bike, via doing modifications to my existing GIANT brand bike which I've had for about 30 years. Needing to get into an e-bike as cheaply as possible due to my funds, I bought a e-bike front wheel kit for around $200, which came with everything needed - except for a battery. I decided to be different, so I bought a set of four 12 volt SLA (sealed lead acid) batteries, each 12v 22aH. My bike was awkward and heavy, with four heavy 15 pound batteries attached to various places on my bike, adding nearly 60 pounds of batteries. In hindsight I do NOT recommend doing this, unless maybe for a tandem bike. While it worked well at first, I could not handle the extra weight (the bike weight 100 pounds MORE than when I started (motorized wheel (40 lbs) + controller (2) + 4 lead acid batteries (56) = 98!). I needed to install a double kick stand (like motorcycles where you hold the kick stand to the ground with your foot and roll the bike backwards to engage the double piped kickstand, where the wheel is then off the ground when using the double kickstand for stability. That is how heavy it was! I also had a couple of the batteries come off the bike and crash to the ground being dragged by my connecting wires in my first few rides before I had properly secured eaech of the four 12v batteries to permanent places on the bike, causing damage, and some acid to leak out and evaporate on the batteries, such that by the second season (this season), 2 of my 4 batteries were no longer working with any power or keeping a charge. I was ready to replace those four lead acid anchors with a single 48 volt Lithium Ion. This was just a couple of weeks ago. Wow! I have nothing but GREAT things to say about this battery:1 - It definitely came in less than a week - despite original estimate indicating it could take 2 or more weeks2 - Best price I've seen by FAR for a 48v 1000 watt Li-Ion battery rated at 20AH.3 - There's so much MORE power than my four 12v rated 22AH batteries in series ever had. It might be because this is actually a 52 volt battery, but my top speed of my spinning front wheel (zero friction, when I just lift the front end off the ground and hit the throttle), went from 36 MPH to 40 MPH. On the bike path when I opened her up (with no one around), I got it up to 32MPH. Even right from starting off from a complete stop, I can feel much more power and torque with this battery.4 - No sign of running out of steam. I've taken it out 3 times and between some peddling and plenty of using the motor only, my FULL----EMPTY gauge has not come down even a SINGLE LED PIXEL! Also, even with the old lead acid batteries, even when brand new and charged, when I could hit the throttle wide open from the start, letting it draw over 1,000 watts, I USED TO SEE the LCD display gauge showing starting with all FULL----EMPTY pixels solid, to at least 2 or 3 pixels going dark, indicating a big drain on the battery, but that would return to full again when letting off the throttle. WITH THIS BATTERY, I have never yet seen ANY movement (drain) on the LCD when I hit the throttle wide open from the start at any time. The other area of the LCD shows I am drawing 1,000 watts, for 30 seconds while I am getting to full speed, but the battery "fuel gauge" never moves at all with this battery, as opposed to showing temporary draining during heavy throttling with the OLDER batteries.I know it is early (I have been out 3 times to the bike path, and have not yet even once charged the battery yet), but I hope the performance remains in the current range, because this battery is a powerhouse, and has not yet shown any sign of needing a charge yet after about 60 miles of riding (about half of that was using motor/battery without peddling). So I would guess that this battery would do upwards of 50+ miles if I never peddled at all, and used only the battery (for sure if I stayed in the 12-15MPH range and not always gunning it)

with 20AH rating I get a lot more range on this battery

I use this for my Bafang 750w motor on a mountain bike. After charging and using it on a couple of rides I am completely satisfied with the product. I received the battery well before the shipping information projected. I recently got 40 miles from moderate to heavy useage. The battery stayed cool and really delivered! With a little more planning I’m sure I could top 60 miles!I love GoodPoint Art and will use them again!

good battery, but....

I’m very happy with this product so far.I’m currently using it on an oset 20.0r electric motorcycle. It’s a huge upgrade to the original lead acid batteries. The only issue was my own fault I should have looked at the dimensions of the pack and asked they they could make it in a slightly different shape to fit in the original battery pan. I have several oset model motorcycles so once I have more thoroughly tested this battery I plan to purchase another.

Replaced 4 lead batteries with this one in my scooter and lost 45+ pounds. It came with a charger. The leads for connecting the battery to the motor have 30A Anderson connectors. I added them too to my scooter to get a solid connection. Perform about the same as lead batteries I replaced. Love the fact that this is a light weight replacement.

Nice build very good construction long lasting battery . Would like to see company offer a bag or case to store battery in. Maybe in near future.
