Reviews
Below are some critical reviews about Unit Pack Power UPP BatteryUpdate:After 26 back and forth emails the seller agreed to replace the battery. I did have to send in my battery first. After they received the battery they sent a new one. I received it on June 29th.I received this battery on May 19th. I used it for a couple of weeks with light use on my EBike. It won’t hold a charge anymore. The pictures show the charge with it plugged in at 59 amps and not plugged in at 3.5 amps. It has been fully charged. The charger voltage output is also 59 amps. Contacted seller for a refund or replacement. After sending in the requested picture they want more pictures of the battery cells inside the casing. I really like the sturdiness and design of the battery. I hope the company does the right thing and replaces the battery or refunds me the full purchase price. I will update this review once I reach a resolution with the seller.
6 months in and my power switch stopped working, I don’t leave it in the rain always comes inside with me. I would buy somewhere else. I tried getting ahold of the seller and could never get to anyone
Used battery for 3 weeks. All was great. Rode over a pothole, battery stopped working. Seller recommends sending replacement BMS. I am hesitant as the battery was 3 weeks old, and I dont want a rebuilt battery. Still waiting, over 15 days for BMS, being sent from China. The BMS is not stocked in U.S. warehouse.Update:The BMS arrived, I installed and the battery was good for awhile. In August, the battery would cutoff at 54V.After they told me how to diagnose with a multimeter, it was found that a group of cells died and would need to replace battery. As they did not have battery in stock, I paid $160 to upgrade to Panasonic cells.Everything was good until January. Battery would take full charge to 58.8V but Voltage would drop to about 55V as soon as my ride started. Today on my commute the battery caught on fire...Waiting to see how UPP will handle this now
Below are some positive reviews about Unit Pack Power UPP Battery
First i want to commend the vendor for speedy delivery.. I received it withing the 3-5 day window they advertised. Also, my review will be very limited for now. As i have just received the unit. the battery was a bit smaller than i expected.. But that is ok, as long as it has the wattage it should have.. I pressed the battery status button on the battery when i received it and i think either one LED lit up for a moment and then went out.. So i presume they shipped it with zero level of charger. I am a little concerned about that.. because i have read lithium batteries should not be held at such a low state of charge.. I did measure the voltage and it indicated there was 49 volts of charge in the battery. Sadly, the USB did not produce any change when i plugged in my iphone charging cable with my iphone attached. my iphone showed there was no charge. This was concerning. Later when i pluged the battery charger into the battery and began charging the ibike battery. I noticed the USB charger was producing a charge to the iphone.. and when i would unblug the battery charger from the ebike battery it would stop.. THis is leading me to believe the wiring of the USB charger was mis wired. I contacted the vendor for help to sort this out. I had bought hte battery so i could charge usb devices while out and about using the battery. I will update this review once i have received a response fromthe vendor and the issue is resolved. I ordered the 48v 13ah battery they sell.I dont have anything else to add yet. I have not yet plluged it into my ebike and tested it on a ride. and see how well it works for me. I have high hopes that the usb charging port problem will get resolved. The manual they provide does not appear to mention the USB charging port and explain the specs on it. such as voltage output and amperage output or total capacity , how much total juice that usb port can put out on a fully charged battery.8/24/20 update: I have been in email correspondence with reps at Unit Pack Power.. trying to sort out why i was not getting any power to the USB port. My oringianl review that there is no reference to USB port on how it works and how to make it work is not in the manual (perhaps the vendor will add this to the manual in an update) I got an email, apparently form soneone in China, providingme with some answers to my question on the UBB port and how to turn it on and off. Apparently you need to swicht the battey in "on" position tnot only turn the battery output, but also the USB Port. the USB port produces about 1amp of poer and about 13000mAh.s according to the customer support at the china center for the factory. I agreed to increase my star level to 4 stars for now.. I still need to test the battery some to get a better sense of the quality of the battery. . I think the manual needs more work. The customer service, although very quick to respond, was not very good with resolution of the problem . they offereed to send me a replacement battery then later wanted me to remove the negative rating. I can understand them wanting me to provide or to recieve high ratings. And i am very willing to give high ratings if i feel they are warranted. The battery is very new looking and immaculate .. no scratches or anything. it appears they took good gacre to keep the battery prestine. they provided a slick compact charger and some addicgtional cables for conecting to my ebike. The manual had decent size print.. but i coudn't find any reference tothe USB port and how it works and the specs on it.. I am not sure what happenned.. but instead of the battery being delivered to my door it was left down at bottom of stairs. And strangely. my notification from amazon said someone had signed for it. I had not authorised anyone to sign for it and no one from my home was there to sign for it. THis alarmed me and then also it being left at bottom of stairs unattended and not by my front door concerned me. I don't know what happenned to cause that. I will update this review as i get a chance to propertly test the function of the battery on my ebike.. probably in the next week or so
I've had mine for 2 years now and 1700 miles paired up with a Chinese front hub. It's a well built battery unit. It's taken some hefty impacts and falls with no problem. The wiring and components are a different story. It needs a better storage system.too much stuff to fit in the tiny pouch made for it.
I don’t have a lot of run time but so far this battery is awesome. Tons of power for my mid drive e-bike.
