Análisis de causa
When the rider is on the vehicle and in motion, the battery pack experiences a power drop under load, unable to provide sufficient electricity to propel the scooter with the rider on board, or the motor may stall and run unevenly under load.
This could be due to the battery pack aging, wearing out, or experiencing internal faults. Además, issues with the charging system may prevent the battery pack from charging properly.

Deep Charging
|
Sometimes, a lead-acid battery pack needs a deep charge to balance the cells and help restore capacity. Try charging the battery pack for 48 a 72 hours and then see if it helps. It’s good practice to perform a few deep charges annually or when significant capacity loss is noticed.

Testing the Battery Charger Port
|
If the battery charger is plugged into the wall, unplug it. Plug the battery charger into the battery charger port on the vehicle and check if there is an illuminated indicator light on the battery charger. If the indicator light on the battery charger lights up, this means the wiring and wire connectors connected to the charger port are good, and the charger port itself is also good. Not all battery chargers have an indicator light that illuminates when the charger is only plugged into the vehicle, so if the light does not come on, you should perform a secondary voltage test with a multimeter as described below.

Testing the Battery Pack
|
Remove the battery pack from the scooter and take out individual batteries to load-test their cells.
You can then test each battery using an automotive battery load tester.
Most entry-level automotive battery load testers apply a 100-amp load to the battery, which is too high, so a variable carbon pile battery load tester should be used and adjusted to apply a 30-amp load to the battery.

Testing the Battery Pack Voltage
|
After reading the voltage, you can use the battery charge state chart page to determine the percentage of the charge state.
A good battery or battery pack will be at 100% charge state after being discharged and left for a few minutes, or if stored. If the battery pack does not rebound to a 100% charge state within a few minutes after being discharged, it indicates the battery or battery pack is faulty or worn.
When a battery pack has been charged to a 100% charge state and its voltage drops below 100% charge state after being left for some time, this indicates the battery pack is faulty or worn.
Good batteries and battery packs will recover to a 100% charge state within a few minutes after the vehicle has been driven.
