[HELP] 9398 Crawler on 10V using DC/DC Regulator
ddimkin posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi guys, I am just expecting my 9398 to arrive soon and would like to be prepared with rechargeble battery supply. I do have a bike lamp which operates with this Li-ion battery pack here: http://www.ebay.co.uk/itm/Led-Lamp-6400Mah-18650-8-4v-battery-Pack-for-xml-T6-P7-LED-lamp-/251001613660?pt=UK_SportsLeisure_Camping_LightsLanternsTorches&hash=item3a70dcad5c and the charger for it. So, I would like to use the pack also on the crawler. The pack consists of 2 x 2 18650s connected in parallel and then connected together in serial. I am not an electrician but the output voltage should be something between 8,1 volt (measured today after a fully charging) and 7,4 volt after some usage. So I was thinking to use the above battery and increase the voltage on the motors by using 2 of this regulators: http://www.ebay.com/itm/321283653204?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 One regulator after the IR-receiver and before each motor. Possible?? If not, how about connecting the battery pack directly to the IR-receiver? I saw some tests and the crawler performs quite well with the Lego Li-Po battery. What do you think performance-wise?? Best regards, Daniel
