Severe Lack Of Run Time With 24V 16.0

[waynerobshaw]

Hi all,

I recently bought a second hand 2012 24v 16.0 and are struggling to get more than 20 minutes run time, infact the leds in the throttle show "low" after about 5-10 mins. Surely i can expect better than this? So far ive tried:

2 sets of new batteries

Checking for excessive drag in the drivetrain (the motor is notchy when spun but i get this is normal?)

Checked the balance of the batteries

Charged the batteries with a car charger as well as the oset one

Any thoughts anyone?

Cheers

Wayne

I would say you have an issue, possibly a short or fault draining the batteries. I have a 24v for my 9 year old and get at least an hour, longer if she is practicing on the flat ground around the neighbourhood.

The only way to diagnose these types of problems is to get yourself a watt meter, they are not that expensive but worth there weight in gold for fault finding. http://www.giantshark.co.uk/product/171035/gt-power-130a-watt-meter-and-power-analyser

Yes, same here. Although a newer set doesn't last quite as well as the originals. Still about an hour.

One set easily does a conducted trial, providing the kids don't ride around too much between sections.

I think I read somewhere that there was a problem with the gauge of the cable that links the two batteries on some of the 16 24v.

Might be worth checking.
