5/5

posted Jun-20-2011

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.
