cptkent Posted September 6, 2018 (edited) Hi, I'm looking for a smaller alternative to the traditional PV battery box. Has anybody used part number 4760c01 (Small 9V battery box) with PF motors before? https://www.bricklink.com/v2/catalog/catalogitem.page?P=4760c01#T=C Thanks David Edited September 6, 2018 by cptkent Doh. Part 4760, not 4750... Share this post Link to post Share on other sites
supertruper1988 Posted September 6, 2018 You can use it to power the IR receiver with one of the extension cables (https://shop.lego.com/en-US/LEGO-Power-Functions-Extension-Wire-8886) but as far as I know there is no way to directly power the motors with that box.
