i have been using this battery box for a custom tank i made. it requires four m motors to make (two for the steering and one for each cannon i have mounted on the sides) it can easily cover the power needed to operate it

I bought this to build Technic RC cars (which are awesome). It works with my Amazon Basics rechargable AA batteries and last for many hours of driving, much longer than I thought. So long, that I wish there was a AAA battery pack designed to work with Technic. When I go to build this into our creations, I always find the pin holes are not where I want them. I wish there where holes oriented in all three axis. I also wish the pin holes where near the corners of the battery box. There is a lot of room for improvement on this design, including making it less awkward to mount and perhaps more compact.

A few suggestions for improvement.

By Taris

from Woodridge

Comments about LEGO Power Functions Battery Box (8881):

1. One of batteries is getting fit into a painfully deep slot. You might flip your fingernail if you try to pry it out without any tools. Maybe install a simple cloth thread piece or a flexible film to help out battery extraction? 2. Six 1.5 V batteries are actually making a series connection: totaling 9 V output. So, why not just use a single 9 V battery instead of heavy and space consuming 6 AA batteries? 3. I know this is a toy and needs to be super safe. But the current output is a bit lacking. (I believe it clamps at around 800 mA?) It cannot operate two L motor with 2 kg of load continuously. The fuse kicks in too early. 4. Li-Ion batteries are being used on every mobile devices in these days. You can purchase them (even AA sized ones) in many tech shops or Amazon. Each of them provide 3.7 V of output. So, why not rather make this thing by thinning out 3 of AA slots to use those Li-Ions with a FET to regulate output voltage to 9V? It's gonna save a lot of space while improving operation period a lot!

Comments about LEGO Power Functions Battery Box (8881):

Still working on the builds in question,so the part hasn't actually been mounted yet, the previous one got mounted in a project that is still also in the works, and is leading me slowly to designing and building with the studless technic liftarms which is a very different experience v/s just building by the instructions.

I really wanted a battery box to use with my power functions parts. I like that it can connect to my brothers train along with my MOC cars.

An intriguing design and size

By Volcanorupt

from Undisclosed

Comments about LEGO Power Functions Battery Box (8881):

A reliable power pack that gives a punch to your creations. It's cable plugs are easy to detach and attach. Serving as a weight add-on, it can stop imbalanced creations from toppling over. Giving necessary power to it's other components and serving extra weight, this battery pack comes in handy for both novice and expert creators to use and enjoy with family and friends. I would highly recommend this product!

Fantastic

Comments about LEGO Power Functions Battery Box (8881):

Great battery box. It requires 6 AA batteries. Long battery life, but some batteries are hard to take out and replace. I would get multiple of these for best motor life.
