battery Question

[-Savage-]

Forgetting about fitting it in for now, but would it be possible to wire another battery in parallel to the one already in my bike, and have it charge alongside the normal one?

I have fitted new lights to the bike, and when at low revs the bike nearly stalls, but only when these new lights are turned on, so im presuming they are taking too much power from the battery. So the only thing i could thing of was to pop in another battery (i have one here which is in working order).

If you have problems running with new lights how do you expect it to be able to handle chargeing 2 batterys?
Your alternator cannot handle it!
Get rid of the new lights and fit a higher wattage bulb to your original head light.

how about try and adjusting your tick over so it runs at a higher RPM.

How about just getting 1 decent high capacity battery instead of messing around with cheap low capacity ones?
