A few issues at first
First This has turned out to be an awsome battery.
When I first got it it wouldn't charge some times unless I wend direct with it and when charged it would work great then turn off for no reason at all.
The turn off was the meter wires had to much solder and were touching intermittently and the bms was sensing a short circuit and shutting down.
The charging problem was when they built the battery 3 of the sensor wires weren't hooked up.
must have been built on Friday.
When problems were corrected all has been well.
I have been using this battery for over a year now with over 20k miles on it and it is still going strong as new. I am getting 30 mile range out of it and it is recharged every night.
Very Happy with it.
