Reviews
Below are some critical reviews about HAILONG 48V 10AH Lithium Connectorthis battery drains ridiculously fast and now its not even charging i got mine 2 months ago and its already dead i would ride my ebike for about 20 minutes and the thing was already out of power and needed to charge and now my charger is always on green that means its not charging anymore. dont waste your time with this its not worth it. >:[@#$%$]
The specs are wrong. It is not a 14ah battery. It's 2/3rds the size of other 14ah batteries. When tested side by side, it is obvious that it is not a 14ah battery. I doubt is the other information by this seller is correct.Pass this up.
This battery killed two different controllers on my ebike.... expensive mistake to buy this battery.

DAY 15 - BIKE METER DEFECTIVE - NOT THE BATTERY - Bike meter won't measure new or old battery correctly.DA ENERGY has sent me 4 emails explaining that the correct operating voltage for this battery is 42 to 29 volts and that near the end of the charge the voltage drops. GOOD COMPANY OFFERING SUPPORT.They also wanted to know how far I could ride with one charge. GOOD MEASURE OF A BATTERY!Apparently the meter on top of the battery is a voltage meter. Which is why I got incorrect readings about the "charge"Charging fills up the battery capacity to deliver amperage.SO, I am now riding my with a voltage meter across both wires and have split one wire with an amperage meter to judge actual performance.So far I have done a 5 mile ride with no voltage loss and amperage going from 2.5 amps available at the start at full load to 1.8 amps available at the end of the ride.I now plan to connect my old and new battery in parallel to see the performance of the combinationDAY TWO - THREE PROBLEMSBattery won't charge. Today is Thursday Sep 9. Received battery Tue Sep 7.There were minimal instructions and I read them carefully. They said to charge battery fully before first use. Meter on the battery showed 1 blue light (low 25%)Plugged in the charger, light on charger went from green to red indicating charging was occurring.In 1 hour, meter on the battery showed fully charged (four blue lights). WRONG READING. My electric bike battery took 4 - 6 hours to fully charge and this is a bigger battery.(1) DEFECTIVE (FAKE) METER ON BATTERY. Also light on charger still red so battery is still charging.At 2.5 hours, charger light turns green. Still TOO SHORT A TIME FOR FULL CHARGE. AMAZON WEBSITE AD IMAGE #6 says CHARGING TIME 6-7 Hr.(2) THIS BATTERY/CHARGER COMBINATION WON'T TAKE A FULL CHARGE.Connected battery to bike. Bike meter shows 50% charge. Tried 4 more times to fully charge battery (in short bursts to avoid heating and overcharging problems). No progress.Took a short ride. Bike Meter at 50% went to 30% in 1 minute and then 10% in 10 minutes.And the defective (fake) meter on battery still shows it is at 100 percent.(3) REPLACEMENT OR REFUND REQUESTED.Amazon Website image 6 says:1000+ (charge cycle image) , 12 months warranty , 3 year+ (Warranty Shield image.)The Amazon page is First Class American Marketing!But what kind of company is DA ENERGY?And do they have NEW batteries, that can be fully charged with meters that accurately reflect state of charge in battery?I request a refund or a replacement.Day Seven:The seller is offering some communication and their response was timely (within the two days.)I am still learning about the Amazon message system (found it under Account) and trying to learn about their new automated message bots that prevented me from contacting the seller (an Amazon representative had to get involved (when I finally found the hidden phone number) and was extremely helpful as usual.)The email the seller sent went to a wrong folder in my email browser (my mistake) so I did not see it until today. I have sent a copy of my detailed review (above) of my experience to the seller DA Energy.In addition, I have purchased two multimeters to try to measure battery and charger voltage and amperage while charging and while not charging to see if I can better describe what is happening.So far the reading indicate a problem, but the cause is confusing, and may also be my test rig.Review now 2 stars.
Built my disabled Dad a 3 wheel bike to give him some freedom. It is powering a 36V 750W Electric Wheel. His first ride was 28 miles round trip and still had about 25% This battery was worth every penny so far.
So far, so good with this battery. I will have to see how well it lasts.
