I've hit a slight snag. My battery was meant to arrive yesterday and still hasn't come. Now it's a very quick job to hook it all up (there's space and mounting holes for it already, 15 minute job at the very most). Buuut just in case it doesn't arrive by tomorrow (which will leave me with a battery that makes me 90 grams overweight) does anyone have a spare they'll be willing to lend/sell me?

Many thanks.
