    Help debugging Kelly KD controller

    I'm currently trying to get my setup with a PM motor and my Kelly KD 72401 controller to work and having some issues with it. Basically I have it wired as shown in the manual. The only problem is it does not give me enough voltage from the RLY terminal to run my 12v-24v nominal contactor. With...

    Help troubleshooting with Goodrum BMS v2

    Long story short I have a Goodrum BMS v2 which I've assembled and I'm stuck trying to test it. Unfortunately I'm stuck and my electrical engineering skills are pretty rudimentary. What I have is a rather nifty 72v Headway battery pack which I am trying to charge with a Zivan charger specially...

    Advice Needed - Headway vs Thundersky

    Ok, this is a question that I've been flipflopping on for about a year now. So far I've been able to put it off by saying "Oh, well I don't really need the batteries until X is finished" but now it is the home stretch, I've got everything I need except the batteries. So for my motorcycle with a...

    Zivan Charger:What kind of plug is this?

    So I have a Zivan charger I want to use for my LiFePO4 pack, I had it sent in and rechipped. Unfortunately I never though to ask them what kind of plug it is using for output. I was told it was an anderson powerpole but after comparing it to a powerpole it does not appear to be one. Can somebody...

    Stringing 36v chargers in serial

    I am having trouble picking a good 72v charger to test my open BMS on. I may just take pgt400's advice and string together 2 36v chargers to make a 72v charger. If both are identical with the same current and voltage limits it seems like it should work. My question is would they share voltage...

    Choosing a 72V? charger

    So this weekend I'm putting together the Open BMS that I just received in the mail and my thoughts are turning to how to test it once all soldered together. I don't have my cells yet so that would be a problem and I also don't have a charger once I get the cells. So I'm looking for a charger...

    How many parallel LifePo4 per BMS

    I'm still struggling with either buying a Headway battery pack or buying the individual cells and using Gary's BMS. So that leads to this question. I don't want to build, test, and debug multiple kits especially since I'm planning on going 24s6p for my full pack. So in the headway thread Greg...

    Headway Pack or Thundersky Cells?

    The time is nigh for me to make a decision and finally decide on a pack to buy. So I'm looking for some advice on what I should do. I'm trying to decide how to build my 72v 60ah pack for me eMotorcycle. My constraints are that I wanted at least 100A continuous and 40mi range. Originally I was...

    PMG132 or AGNI Motor?

    I'm getting to the final stages before I go ahead and order my motorcycle parts. I know these typically aren't used on ebikes but I've seen both of these mentioned here before. In particular I've heard that the Agni is more reliable and more powerful. Unfortunately I have no information to back...

    Managing Thundersky Batteries

    I've posted before about doing an approximate ~5 kWh pack and this is just a continuation of solutions I'm looking at. So I was wondering if Thundersky LiFePO4 batteries were any good. I've read different blogs on E-motorcycles which successfully use them and they seem to be fine. My main...

    Running Ping Packs in Parallel

    Is that a smart idea. I'm trying to build a really big system ~5000 watt hrs for a motorcyle and I just worry about SLA being too heavy. So I keep coming back to LiFePO4 and Ping batteries are the ones that people can't stop talking about. I know he sells 36v 16ah packs, so would it be possible...

    Quality of Different AGM batteries

    I was thinking about going LiFePO4 but I've realized that I'm not as limited by weight on my motorcycle and can go with the cheaper AGM batteries. However I don't know which kind of 75ah AGM to get. Could anyone tell me anything about the quality of some of the following brands. For reference...

    Regen questions

    I'm building an E-motorcycle for my 30 mi commute and am wondering if I should get a controller with regen capabilites. Clearly recovering a bit of power every time I slow is an attractive deal but I want to know a little more about how it would work. When using regen from a controller to a DC...
