"All I can say is WOW! Everything I read about PingBattery building a superior product is absolutely true!!
Ping answered every single one of my questions with honest, caring responses.
I was very concerned about the product and outcome of the transaction but after this experience, I'll be coming back for more when I'm in need.
My 36v 20AH battery has preformed very well! It exceeds expectations, depletes slowly and has more than enough juice to get me to where I need to go.
If I had to say something negative it would probably be the weight but it still beats a lead acid battery ANY DAY!
Overall the energy capacity VS the weight is well worth it. If you are building your own electric vehicle or bicycle, PINGBATTERY is the way to go!!
It's been a great experience, Thanks Ping!!"
"I have owned a ping 48v 15ah since 2009 and used to commute to work (in my ebike) with never a problem. Recently I bought a 5 amp charger to speed up charge time and it arrived in less than a week which is great when you live way down in New Zealand. Thanks again great service.

"I have owned an e-bike since 2006, I bought 3 one for me, my brother and son.
The batteries that came with the bikes where Lithium Cobalt 36v 15ahr and two of them are still working but just barely.
When mine died I bought a Lithium Polymer 36v 10.5ahr , the battery was ok for a year but quickly lost capacity and is now junk.
In need of a good power source I have bought a Ping 48v 15ahr for me and a 36v 10ahr for a friend.
The batteries left Pudong International Airport on June 10 2011 at 11:00pm and where shipped by TNT Express because of a possible postal strike here in Canada.
They showed up at my door June 13 2011 at 2:00pm really fast shipping for only $10.00us more.
I have done some load testing on batteries and the Ping batteries are fantastic.
The testing I have done with my e-bike show 0 to 50 kmh in 12 seconds and incredible torque so much so that you must be very firmly holding the handle bars when you go full throttle or your leaving the bike.
There was one small issue with a 2A charger being sent instead of the 5A I have ordered.
When I e-mailed Ping on this item it turned out to be a packing error as all ping batteries get a 2A charger free.
Ping sent me a replacement the next day and tolled me to keep the 2a charger as a spare.
Ping has answered any questions I have had in a prompt and exacting manner.
Think about this when you need a GOOD power source and customer service that cannot be beat.
My One year Report on my Ping 48v 15ahr Battery
From the above you can see the performance of my Ping Battery when I got it a year ago.
My run to and from work, is 25km each way, 50 km a day.
My best time has been 33 minutes, it cruses at 43 to 47 kph, Up any hill ~ 41kph, down hill you’re in your 50ths.
The battery has the same power now as it did when I got it and it’s the same at the start of the ride as it is at the end.
I keep a record of all rides and at a cruising speed of ~45 kph will take me 51 km, at 32 kph it will take me ~76 km, before cutting off, I have tested this and know it to be true.
The Ping battery is simply the best battery I have ever used, there are NO challengers.
I need my ebike because I have a medical issue with my lungs and this battery allows me to ride like an Olympic rider .
Ping is most definitely a 10 in service and product.

"I ordered the 48v 20ah battery with high rate charger and bms and it is totally awesome.
Running it on my old Nishiki mountain bike with a
Magic Pie motor. After 45 miles on a bike i am worn out, the battery is not.
Li Ping is a great pleasure to work with. Very prompt service and very prompt replies.
To bad you can only give him 5 stars, Li Ping is a 10."
"I bought a 48V 10Ah battery package from PingBattery and received it a few days ago. I'm amazed with the performance of the product, the high quality packaging for intercontinental shipping and the customer support. I'm no pro at electrical stuff and Ping helped me with lots of my amateur questions!
HIGHLY RECOMMENDED! I wish all internet transactions were like this!"
"best money i spent on a battery, moves my trike along well"
"Bought a 36V/15Ah from Ping. Excellent follow up with delivery. The battery is awsome and runs my e-bike as never before. Excellent!"
"I bought a 36v 10ah LiFePO4 battery pack from Ping in 4/10. It has been charged numerous times so far and is still going strong. No problems whatsoever!! Ping has been very responsive to all my questions. The charger that had originally shipped with above battery quit working after the warranty had expired. When I had inquired about a replacement, Ping replaced it for FREE! and I received it in 4 days. "WOW" Now that is what I call great customer service. I highly recommend this seller.
Thanks again,
Richard"
"To: Ebike Dealer from Happy Ping Customer:
The answer to the problem is a Ping 48 volt (10 or 15 ah) LiPo4 battery.
I got the new battery (48v 15ah) and its amazing.
Plenty of power for any hill and I go 30-40 mile without feeling any loss of power(never cuts out ).
The battery is top quality and works exactly to specs with excellent very knowledgeable personal service
(got a complete personalized education to make informed wise spending decisions).
(increased quality at about 1/2 the price per unit of usable power and longevity compared to the original kit battery)
I received the battery in CA in 3.5 days from Shanghai including a day in LA customs.
Just some user notes/experience for reference:
"
"This is the second buy I did from Ping. It's the third LiFePo4 PingBattery I got. One year ago I bought two batteries (48V 15Ah) and they are working great! Last month I bought one more battery (36V 10Ah). It's a very reliable product and I can really trust the seller. Everything is OK. Thanks Ping! Greetings from Curitiba, BRAZIL."
"As ever another perfect purchase of a battery pack from Li Ping.
Li Ping works tirelessly to provide a first class service, to solve any problems and to provide a bespoke configuration, as the customer requires. I had one battery made to order nearly three years ago and it has been brilliant! My latest purchase was made to the size I required and delivered extremely quickly.
The batteries are of good quality and at very competitive price; can’t fault the service.

"My Ping Lifepo4 48/15Ah is used with a 48V/750W controller and a rear hub motor Bafang BPM code9.
Without load max speed is >60Km/h
With load on a flat ground and moderate pedaling speed is 50Km/h
Max Amps peaks is >43A
Max power peaks is > 1600W
The weight of the battery pack is definitly higher than a Lipo, but it works very well !
when I pull 1500W and 40A the battery desn't drop lower than 48V !
This battery pack is exactly what I wanted !
The order follow-up, the help to define the right pack, and the contact was excellent with Mr Ping !
Delivery time and packaging was excellent too ! No surprise !
Many thanks Mr Ping !
Good price !
Good product !"
"I bought a 48v 20ah LiFePO4 battery pack from Ping in 8/08. It has been charged about 500 times so far and is still going strong. Ping has been very responsive to all my questions. I also bought the 5A charger to speed the charge cycle but ran into a problem. After a couple months, the pack would stop after a few miles! After several rounds of troubleshooting, it turns out I wasn't leaving the charger on long enough to balance the cells, even thought the charger light was green. Lesson learned. Ping was great the whole time, I highly recommend him and his battery."
"I have been very satisfied with Ping Battery. I have ordered many products from this company and I would recommend them to anyone looking for high quality lithium phosphate batteries and accessories. The manufacturing and shipping time has been very timely. The customer service has been outstanding! "
"Purchased a 60v, 20Ah LiFePO4 pack with a 5A charger. This is my second pack. Last year purchased a 48V, 20Ah with a 4.5A charger. Both packs have performed flawlessly. Last year Ping sent a 1.8A charger by mistake and when informed promptly sent a 4.5A charger for free. From my research and conversations with folks on the endlesssphere and my own experience, Pings prismatic cell packs are the best value in this category.
I have not tried A123 or thundersky as their form factor is inappropriate for my application which is a velomobile.,"
