What is the last thing(s) you bought?

[w00p]

Get yourself a pack of R/C hobby spec NiMH or LiPo batteries of around 3700mAh.
In fact make sure you have multitude\'s of how much you need, then put the packs parallel. Yay for 7400mAh and 11100mAh! :o
That should keep you playing for a small week.
And after a few normal batteries have gone through it, it\'ll have you even on your money and afterwards save it for you!
