Batteries

[jodawill]

What kind of rechargeable batteries do you guys recommend? They're really expensive in stores and I need a bunch of them for my Brickworld display.

I'm looking for some cheap ones on eBay, but I don't want to buy anything that's dangerous. The brand name batteries don't seem to be any cheaper on eBay than in the stores.

What about buying a control centre module V2 then connecting your displays to mains power?

V2? Do you mean there's one newer than this? http://lego.wikia.com/wiki/8094_TECHNIC_Control_Center?file=8094_Technic_Control_Center.jpg

I'm going to be using both types of power cables though, the old 9V and the new RC style.

Yes, there is a newer one, though it came out many many years ago 8485-1

It looks like that would be even more expensive than buying batteries.

I use standard chemical batteries but people usually recomend Sanyo Eneloop.

you could build your own power supply, I use an old PC switch mode 400W. Also I use smaller 1a switch mode power supply for charging my Litihium Ion packs and powering Lego PF, just requires a little soldering.

I might try something like that. I could use a 9V AC adapter.

Make sure it's DC output. AC output would cause motor to spazz out trying to run in both direction and it may damage IR receiver.

I recommend the Amazon Basics, purchased on Amazon for a fairly low price. They are among the best in terms of performance. These batteries are Eneloops, but with impressed mark from Amazon

NiMH in the largest mAH you can find or something custom.

http://www.harborfreight.com has there brand @ 2200 mAH. Their brand heavy duty non-rechargable are excellent. They seem to last forever. As long as you don't let their rechargeables go dead, there great too.

I use these in my Unimog:

If your creation is stationary, you should consider a 9V DC adaptor. Strip the wires, solder a couple of alligator clips and attach inside the battery box. Make sure to attach the + with the + and the - with the - and that your adaptor puts out the required amperage (maybe someone who knows what that is can chime in).

I'm sure there are more elegant ways of doing this, but nothing will beat being plugged into a wall socket for running an exhibit all day long.

I use quite a few of these;

They hold their charge well.

I'll add one more voice to those saying that a mains-power solution is full of win.

I knocked something together from an old PC power supply. It does require a bit of soldering, but once you're done, you have as much power as you can eat. I wrote up what I did here http://www.lugnet.com/~2801/PowerSupply.

If you don't want to go so far (which you probably won't unless you're using several motors at the same time), it's relatively easy to hot-wire a battery box to plug into a standard 9v adapter. There are lots of resources on the internet (including plenty of threads from this forum) to help.

Good luck!

Owen.

If you can build the custom power pak that is the way to go.
