$20, rechargable, normally comes with charger and battery. A charge lasts me about 2 weekends worth of bashing. Usually more. I forget to charge the thing.
It will work with the sub-c cell or a normal C alkaline in a pinch. It's my backup one. I have another that's really long that works for my BB engines better.
defo best thing to do,means if you're bashing with mates you can help each other out too as at the end of the day all glow starts are pretty much the same as far as what they do
