Shoprider cadiz scooter, batteries show full charge when first charged up but when driving scooter battery power runs out after about 3 miles. brakes work fine, no noises from motor or gearbox, what's wrong with it?

Question edited for a lot more clarity.
Question moved from Cars and Trucks to Make model category.

Is it tripping the breaker? If so it is likely an issue with the motors or the controller.

Circuit Breaker (Reset Button)
Your scooter is fitted with the latest in electronic controls that are programmed to protect
the electrical system from abnormal overloads. Provided for extra protection is a circuit
breaker, located on the battery pack. Should there be a situation where your scooter stops
for no apparent reason, please check that the circuit breaker has not popped.
NOTE: To preserve battery charge, your scooter may go into sleep mode after being idle for
a few minutes. To remove from sleep mode, turn the scooter switch off and back on again.
Check List
If your scooter fails to operate, please check the following:
• Unit is switched on.
• Drive/Freewheel mechanism is in the drive position.
• All plugs and connectors are clean and firmly connected.
• Battery level shows full charge.
If the free wheel device has been operated with the scooter switched on, then the scooter
will not operate until the ignition key has been switched off and then on again.
Please consult your dealer if your scooter does not run after checking these points.

Check the speed control on the handle bar.

have the batteries load tested as it appears that they have bad cells

The "H" bridge in the drive electronics is bad. Need to replace the drive. Your old battery is probably good - To test my idea, run it at your "low" speed then check the battery temperature with your hand. Is it hot/warm? if yes, then the battery has been working very hard due to the "H" bridge being bad and taking current

Check the wiring from the controller to the motor, disconnect the wire ad clean the connections with a contact cleaner or WD40 , and make sure the scooter not in freewheel mode.

Things to check: Drive/Free wheeling switch, brake release lever (this activates an internal micro-switch that enable power to the drive system, battery box connectors (condition of contacts - corroded, missing, loose. etc.); main control cable (corrosion. lose or missing pins, etc). If all these are OK, could be controller or drive control potentiometers (speed, forward, backward) on the handle-bar (tiller).
Good luck!

Hi,im disabled myself.when it comes to batteries,they gotta be treated as manufacturer says,please let the charger charge the batteries for the time given.Then go from there.I have a shoprider milan scooter.& even if i go 1/2 a mile i put them on charge so they are fully charged,my batteries are the Gel kind.But please read all info on Batteries.You can visit:shoprider.com & see what info you can download as a PDF File,print & keep for future ref,Colin.

Hi Susan, I repair power wheel chairs, Its possible that your chair has a bad battery on it , all p/chairs have 2 batteries.And even though you show a full charge one battery may have a bad cell in it you need to get both batteries load tested . I think you my find one of them bad. take them out of chair and have them tested.You can get replacement batteries , and have yours tested at a store that sells batteries only, look in yellow pages for a battery store . Good luck, Erik

hi Richard,

Does the scooter actually lose power after the 3 leds show ?

If it is losing power then a suggest to try some other batteries to confirm dodgy batteries, check the terminal connections etc.

If it does not lose power then the volt meter is at fault, if you can check the voltage before riding then after it shows only 3 leds , if there is a big drop, check the charger first to make sure the batteries are getting fully charged.
