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...

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...

Yes I am considering the 60AH TS cells. My vehicle calculation spreadsheet tells me I'll be drawing about 60amps continuous when cruising so it seems that 60Ah is the minimum. The problem is I don't know how much current will be needed for acceleration. There will be points where I will need to...

Yeah, while I'm glad this thread has gotten attention it hasn't quite been the attention I'd been hoping for. I still am a bit at a loss as to if Thundersky's would be underpowered for my bike. If I should go with Sky Energy cells. Or if I should just get the Headways. Here is the thread I...

Has anyone found any other ways to make/buy bus bars? For my project I'd have to make more than 40 for the cells in series and that makes me hesitate on headways a bit. I suppose I could pay more for a 1" wide copper strip from mcmastercarr and then use a bandsaw to cut it into 2.5" lengths...

Oh, no way am I going to consider cellman cells. They look amazing but the foil tabs look like hell to deal with. I'm going for something that will provide the "easiest" solution. @ahambone. I have to say that I've seen your pack here and on diyelectric car and the headway pack I envision...

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...

That does seem like a serious issue. I'd be interested in hearing if this is a problem for more users as I decide if I'm going to get headways or not. By the way, Lock, where did you get those cell holders and did you make those aluminum buss strips yourself?

yeah my Zivan is secondhand off ebay. It ended up being 75 dollars to ship it in and get it rechipped but even with that additional charge I ended up saving about 200 dollars on the charger overall. Still that doesn't answer my question of what kind of connector is that? Am I going to be put...

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...

While the 12v pack from ElitePowerSolutions is cheaper , buying 4 individual cells is cheaper from evcomponents for 40AH and up. Of course this is disreguarding shipping. Personally with these price drops I'm still torn between getting the headway or the TS cells from evcomponents for my 72v...

Ok, here is a simple one. I just got a used zivan 72v charger, what kind of plug to I need to interface with the dc out?

I got lucky and managed to snag one off of ebay for $300. It has the following sticker on it. "Micro Upgraded, I2 Increased, T3 Extended" Trojan : U1 85.3V : I2 4A : I3 2.6A : Ur 76.8V: Restart 7 day: 130Ah. I'm wondering if I can use this if I change the voltages but I'm not sure how to manage...

I'm not sure I understand, how does one isolate a charger? Does it mean severing the connection to the ground plug on the input side?

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...
