I have a ping 36V, 20aH battery on my older e-bike. I have been riding the new e-bike, working the bugs out, determining range, etc. and sort of neglecting the older bike for a couple weeks. I topped off the battery on the older bike and took it for a ride after I'd depleted the charge on the new bike and was waiting for it to charge. I can go about 35+ miles per charge on the old bike, so imagine my surprise when the battery died at 25 miles. The analyzer showed 15 amp hours used and at 38.1 volts.
When I got home I put it on the charger. When the charger shut off, only 11 of the 12 LED lights were on, #5 was dark. I ran it just long enough to bring the charger back on and the results were the same, #5 LED still unlit. I'd guess I have a dead cell. I don't want to pay the shipping(over $140.00) to return the battery to Ping in China for a replacement under warranty, but I don't think they have any service providers anywhere near me in NW Pennsylvania.
Does anyone have any ideas? I e-mailed Ping and explained the situation. Do you think I could replace one cell in a LiFePo4 battery? I haven't taken the case apart because I don't want to void the warranty, so I really don't know how these things are constructed. I appreciate any help.
