I believe there is a malfunction of the controller. I have a Revo Travel Scooter, 3 wheeler which has the 2 6V batteries in cases, I replaced the batteries thinking they were older and going soft.
It appears that as the battery has been used for a VERY SHORT period the controller will drop out, I can set for a couple of minutes and it will re-engage but I need to recharge quickly. It is supposed to go 12 miles with the new batteries fully charged, it may go 1 before it starts acting up. The meter will be nearly full right, charge for 5 minutes and the needle will moves a little and the unit will engage and move again.
Is there an adjustment I can make. I would love to get my hands on a maintenance manual as there are no REVO dealers within several miles of me, I am a retired equipment maintenance person and can do more than just tighten a screw. I have a variable power supply that I am going to use to see what voltage the controller drops out and will report back any further information but if anyone has experienced this phenomenon and knows the fix would appreciate the info.Mobility Scooters require 2x 12 Volt batteries. If you’re using 6 Volt batteries, it will not work.
I have3 no idea why I typed in the lower voltage. They are 12 volt batteries and of course are in series and create 24 volts. The problem was correct, instead of getting 12 miles on a charge I only get 1 or 2 at best. I still feel it is in the controller which I am told is a PG (or PNG) S drive. I can’t find any information on how these are adjusted. In spite of my stupid error in the original posting I am a retired repairman and actually can fix things, but hard to do with no information on what the correct settings should be. I do have the general setup for all the units after when mine was made, but nothing on the earlier models. Anyone have any information????
