i bought 3x12v sla/agm 12ah batteries for the kit. yesterday I took it for a 1km ride (more or less) and had quite a good torque. today I took it for and other ride this time about 6kms. I felt a noticeable reduction in torque after around 3km and the controller started cutting out by the end of the ride, especially going uphill. isn't that two early?!
ps: the controller is standard (not regenerative)
the batteries are new and each had around 12.7V when I bought them so I only gave them a 30 mins
charge just to test the charger. the batteries where making a hissing sound, like frying chips, is that ok?
they're not doing that sound while charging today.
anyway I enjoyed the ride, especially when the batteries where fresh!
