Re: Moving to Lithium

I use a 4Ah pack in boner and they use about the same

Re: Moving to Lithium

Thanks for the offer of help Gary, I haven't got MSN though so I'll collect info through other means of pestering..

I thought Li-Fe was more powerful than Li-Po but more stable?

We plan on giving Bitza a spinning weapon, so there will be quite a draw there.

No, because they are more stable the amount of energy per gram is less than with Lipo.

Re: Moving to Lithium

Even with a spinning weapon you won't empty a lipo pack unless it is a very small pack. I could happily get five fights out of the pack in boner, maybe six, before charging if I want to.get yourself a five cell, four ah pack and you will have no capacity or current draw issues. Just follow all the safety guidelines in the rules and use a decent charger

Re: Moving to Lithium

Interesting....

Looking at getting a 5cell then around 2500 - 3000 mah.

Can anyone recommend a charger? Minimal cost, remember it is called Bitza!

Re: Moving to Lithium

Hobby King has come up a couple of times now, the prices look great but what complications (extra cost. price changes) does shipping the to UK incur?

What do people suggest for a PSU?

Re: Moving to Lithium

Obviously postage is more costly, get an account on the site and it'll tell you how much. You can usually get around customs fees but delivery takes longer.
For similar chargers follow Gary's link, can always click 'UK only' for location if you're concerned about importing.

Re: Moving to Lithium

That's more like my kind of pricing!

Do I need to buy a balancing lead separately for Li-Po's ? Or is this everything I need?

Well it seems Hobby King have warehouses in Europe main land so customs should hopefully not be an issue and postage seems reasonable thanks to Li-Po's being so light!

Re: Moving to Lithium

That'l do fine as long as your lipo batteries have the same (JST-XH) connector

Re: Moving to Lithium

I think I'll go with the one Jonny posted earlier;

Although I'll most likely change everything to Deans connectors anyway.

EDIT: Your referring the balancing connector, got it!

Re: Moving to Lithium

don't use cheap lipos

Re: Moving to Lithium

Regarding chargers, I have yet to use (or buy) this one yet but I've been looking at this model from GiantCod for a while:

http://www.giantcod.co.uk/power-a606-du ... 05325.html

One of the reasons I like it is because it can connect straight to the mains, no need to have a separate power supply (I don't like the fact that a lot of chargers need one to work, it's just another piece of equipment to faff about with that takes up space, but that's just me)
Downsides are that it only has the capacity for 6-cell lipos (but that should be more than enough for most people) and that it is supplied with a non-UK power lead, but a simple computer kettle plug would suffice.

There are also a few different models on the site worth looking at, as well as the links provided by others. Definitely worth having a good look around to find the best deal

Re: Moving to Lithium

I never understood why getting the PSU is optional either, its like buying a car and then finding you have to supply your own seats......

6cells is what we're looking at using.

Would advise against the Zippy Li-Po's? What problems do cheap Li-Po's suffer from?
