We have a 21/2 year old Ezee 36v 10amh battery . Used fairly lightly for occaisional assistance by my wife.Terrain is undulating with a couple of steepish hills. Charge every time after use. (16 to 20 miles)
Recently going up the steep ones, pedalling as well, the battery lights go from green to orange and then quickly to red and the motor cuts out.
The battery charges up to 41.6 volts, each cell reads 4.2v. After 8 hours the reading is 41.5v. I did a test ride today, 1/2 mile circuit up a gentle climb and down again and measured the voltage. Each reading at the connector to the controller was 41.1,40.8,40.5,40.2,40.1 and a bit steeper 39.2,38.6. I then checked each cell, they read 3.9v. I turned the bike upside down and let it run at maximum until it stopped. The cell readings were 9 cells at 3.7v and one at 3.4 The reading on the connection to the controller was 25v and after an hour it had recovered to 35.1
Having bored you all with that could it be the bms is cutting out the power on the hills or the one cell at 3.4v.Possibly d8veh will have a suggestion but anyone who has thoughts please reply.
