Thank you, im not very well off, so i have always just looked a stuff i have and figure out if i can do anything with it.
The battery pack i did buy though and it cost me 79 pence lol.
I didnt know that the PCC didnt have a status light. Hmmm that sucks.
Well, it has one red LED. It lights when you're charging the PCC and goes out when the PCC charge is complete. I think it may also light when the PCC needs charging. But there is no indication when you've got a battery on to charge. It's all just guess work on the state of the battery you're charging.

I read a while ago that they were considering a MKII PCC for the Tornado that would have more indicators (like the Titan PCC I guess), but I haven't heard any more about it.
