Hello all
My sister-in-law has managed to leave the battery charger for her eBike out in the rain, and now it seems to not be working.
Unfortunately I haven't been able to go over and inspect it so far, thy are not nearby.
We got her to read out to us over the phone what was printed on the charger, so I could try and work out what would be needed in a replacement.
She managed to confirm that it outputs 42V , 2A, which seems to be a common pattern for charging 36V batteries.
However, despite my best efforts to describe what to look for, she couldn't find anything that defined the polarity of the output.
The bike is a 250W rear-motor. The charger-to-battery plug is that tube type, such as would be used on a laptop.
From my rummagings on the internet, it would appear that most / the vast majority of chargers will have the inner part of the jack as the positive.
Is it safe to assume that ?
I did wonder if the polarity would be written on the battery itself, we haven't managed check with her yet.
Perhaps it might be possible to get a multimeter onto the battery input, but she doesn't own one and wouldn't know how to use one.
So any advice that you would care to offer, would be gratefully received,
Thanks
Best regards
