I have been avoiding using the form again but I'm out of options. Basically, my batteries (which are around 4 months old -- Apex brand) are simply not performing well at all.
The battery back charges to around 27.3 V if I let them fully charge until the charger light goes green. if I let the charger plugged in for 12 hours or more in my get up to 27.5 at best.
I'm using the scooter in fairly flat surfaces with a little bit of an incline here and there, but no serious hils and it has gotten so bad, it barely goes for a 1.5 miles before start running out. And this while using the scooter at very slow speeds, not full throttle.
I tested the batteries after I come back and they read around 26.2 V.
Things I have done/tested/checked:
I got new batteries. 22 ah. Better brand. The problem remains: When I hit the full throttle, it drops to red. It has been like this since I received the parts from your store.
Please let us know if you have any questions.
