    Copper Bus-bar

    Hey there, We're making a 13s14p battery composed of a 6s14p pack and a 7s14p pack. After doing some rough calculations, we think that we need two copper bus-bars capable of carrying a peak of 150A current in each with a nominal of 50A each at all times. It's for an electric go-kart. We're...

    ME0909 Screw Size

    Hey, Just wondering if anyone knew what size the terminals are on the ME0909 (i.e what mm holed lugs should I buy?) The datasheet doesn't say/in chinese Datasheet: https://sep.yimg.com/ty/cdn/yhst-129399866319704/ME0909.pdf?t=1523318830&

    Determining Wire Gauge

    Hey, I'm running a 48V battery to my ME0909 motor and KDZ48401 controller. Continious current draw is 100A and peak draw is 300A for 30 seconds. My longest wire length is approximately 1.5m (from battery+ to one motor connection). I also have a 400A fuse. It's for an electric go-kart...

    Choosing Ground

    Hey, We're building an electric go-kart with a 48V main battery and 18V secondary battery. We have an old go-kart chassis with a metal core structure. I'm just wondering - is there a need to connect the negative terminals of the batteries to the chassis metal frame?

    How to connect wire to battery busbar

    Hi, We're in the process of assembling around 195 18650 cells in order to power our ME0909 PMDC motor at 48V. It's rated for 100A continious and 300A for 30 seconds. Our cells will be joined together by massive bus bars and there will be two main bus bars - each being able to carry 150A...

    2/0 AWG max current?

    Hey, I was just wondering. I'm planning on using 2/0 AWG (70mm2) wire for my electric system to carrying 100A continious and 300A for 30 seconds and I'm planning on using a 400A fuse. I just want to make sure the wire won't melt before causing the fuse to blow. Is 2/0 AWG adequete for this job?

    Wiring Help

    Hi, I'm working on a electric project and I just needed some help. I'm using a Kelly Controller KDZ48401 with an ME0909. ME0909 is 48V, 100A cont and 300A for 30 seconds. We have decided we will use two batteries - a 48V main one and a 18V to power just the controller (controller takes anything...

    Thermistor Placement

    Hi, So I'm looking to get a KDZ48400 controller to use with my ME0909 motor. As far as I can see, the ME0909 doesn't have a built in temperature sensor. Kelly Controller's site recommends to use a KTY84-130 thermistor and connect this to one of the data pins on the controller. My question is -...

    Fuse Selection

    Hey, I'm planning on getting the ME0909(48V, 100Acont, 300A peak (30sec)) motor and the Kelly KDZ48400 controller. I'm using 2/0 gauge wire (70mm2) with 8mm stud ring connectors secured in by M8 screws and washers. In an effort to make sure everything is safe, I'm planning on getting a 325A...

    KDZ48400 Terminals

    Hey there, I'm planning on using the KDZ48400 with a Mars ME0909 motor(100a cont, 300a peak for 30 seconds). All at 48V. I'm really confused on the connections for the KDZ48400. Here is a picture of it and link http://kellycontroller.com/kdz4840024v-48v400aseriespm-p-955.html I'm planning...
