hello all
I recently changed a bottle battery for a dolphin on my ebike,
they have different connecters .
I realised that my bottle battery was fully charged, but had no easy means of discharging it a little

so I have seen reference to discharging battery by connecting bulbs in series.

and have purchased 3 mr60 12v 50watt bulbs and holders but have hit a snag

cannot seem to find idiots guide to wiring up in series, only normal light bulbs

I do not know which is pos neg on the mr60 nothing on lamps or holder to indicate.


so info on how to wire these up pleaseDSCF0465.JPG

Are they LED, or incandescent MR16s?

Incandescent bulbs don't have a polarity. LEDs do, but since they are diodes, they simply won't work if the polarity is incorrect.

you should use 3 x 12V bulbs wired in series for 36V battery.
