You get 2 for about the same price as the one you linked.

are they a better battery or just better cos there cheaper?

I dont know about the performance between these two, but Id rather get 2 packs for the the same price.

imm gunna go slightly of topic here but with the spektrum tx/rx charger (the 2 pin one) what adapter do i need for the uk plug sockets? i have found a voltage dropper one http://cgi.ebay.co.uk/UK-US-USA-Adaptor-Converter-Transformer-Plug-45W-45VA_W0QQitemZ130259491314QQihZ003QQcategoryZ96942 QQssPageNameZWDVWQQrdZ1QQcmdZViewItemhttp://cgi.ebay.co.uk/UK-US-USA-Adap...-45W-45VA_W0QQ itemZ130259491314QQihZ003QQcategoryZ96942QQssPageN ameZWDVWQQrdZ1QQcmdZViewItem
Would this be ok?

If you have a futaba charger you could always just open up the spectrum and swap the positive and negative around on the charge jack.

right. what about charging my 7.2v batts then? im using 2 of them in the robot to make 14.4v but would you charge them as there paired up as 14.4v or charge them seperately?

Yes if in series like you say you add the voltages together, but leave the capacity (Ah) the same as a single cell.

so instead of charging at 7.2v 6 cells on my constellationi put 14.4v and keep it set at 6 cells? will they both charge evenly?

Im not 100% sure on this as I dont use a constellation charger but if you are charging two packs in series it will be equivalent to 12 cells (14.4V) so my guess is you would need to set it to 12 cells rather than 6; hopefully someone can confirm this though

well just spent £121.85 on batteries at component-shop.co.uk. Man this is an expensive hobby. Worth it tho.
