lanesteele240 Posted May 8, 2015 Posted May 8, 2015 I see two types of lego battery boxes. The ones that come in the 60052 set are higher priced than the other one with technic arms molded into it. Is there any diffrence in the circuitry? Could i just use a cheap battery box off ebay with a mini on off toggle. Quote
dr_spock Posted May 8, 2015 Posted May 8, 2015 One takes AAA batteries, the other takes AA batteries. Size is the main difference. What are you planning to do with the battery box? Quote

Thanks for responding. Im going to run the power functions train motor and ir receiver. The current 60052 uses the aaa box and train motor. Quote
marook Posted May 8, 2015 Posted May 8, 2015 AAA is smaller cells = lower runtime. Unless you can find some high-energy mAH cells somewhere.. ? Quote
davidmull Posted May 8, 2015 Posted May 8, 2015 I can't keep batteries in my trains lately. Just ordered 8878. Quote

In addition to less run time on the AAA battery packs, you also may experience a bit of performance degradation as well when compared to that of the AA battery packs. For trains, which are typically meant to be "slow" compared to race car models built by the technic builders, this is not typically an issue. And personally, any gains in performance on the AA battery box is quickly offset by the weight of 6 AA batteries when compared to the weight of 6 AA batteries. But that is my opinion and YMMV. Quote
dr_spock Posted May 8, 2015 Posted May 8, 2015 Also take into consideration of the scale of the trains you're building. The AA box can be a bit too big to squeeze into six wide locomotive. The AAA or the rechargeable box (same size as the AAA) may be the only option if you chose to stick with a pure LEGO solution. I think runtime can vary depending on the weight and length of your train and also the amount of friction in the wheel sets you used. Quote
cgarison Posted May 10, 2015 Posted May 10, 2015 I think runtime can vary depending on the weight and length of your train and also the amount of friction in the wheel sets you used. Very true. Light weight trains and wheel sets with the least friction are the best friend of runtime for any battery box. And for the record, I can not build trains that are light weight or have reduced friction wheel sets. Look at my last 53 stud long behemoth. Quote
