Help required with Rechargable Battery Packs

[TheLegoNewbie]

Hello,

I own the following trains 60051,7938 + 60052 and have just bought rechargeable battery packs for all.

I have noticed that when I insert the rechargeable battery packs into the engine that the hole at the top for the power light can now not be seen.

Just wondering if there were any guides where I can change the trains so that I can see the power lights?

Thanks in advance.

Cheers

We recently finished building 60052 in my house and I noticed the same problem. If you are using the rechargeable pack it should not be much of a problem. It will time out after an hour or so and turn itself off. You lose some power for the IR receiver but since it is rechargeable no big deal. You could probably rebuild it to make a gap to see the light without too much trouble, though I haven't attempted it.

Thanks zephyr I might give it a go when I get time.

Hi,

I'm think about buying rechargeable battery packs for my trains. Is there a particular pack that fits?

Now, im a n00b with trains myself. But you should surely add some more information on what your trains size is in studs.

Searching for power function on the LEGO site, this is what's available. However this was the only rechargable set i could find.

You can use rechargeable cells in all the standard battery packs from LEGO, use their own one, or find custom 9-10V cells and mod a PF connection cable to supply the PF system you use.

If you wanna be 'pure', you only use LEGO battery packs, but who looks inside the models.. ;-)

So the Rechargable battery pack (8878) is the same size as the non-rechargable one (88000) that comes in the set.

Is there any way to hook up to a regular battery pack via Micro-USB? Can you change the lego battery box from USB?

Not without lots of modification to the battery pack as you would need to introduce a charging circuit with protection. If you aren't experienced in this I would suggest against it as exploding batteries aren't much fun.

USB is only 5V. You would have to add an up voltage converter between your USB and the LEGO rechargeable battery box.
