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 the c...

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 tailor...

Re: Advice Needed - Headway vs Thundersky

Assuming a decent cap pack I'd go with the lowC TS and parallel an a123 m1 on top of each cell. I'm not sure how well it would boost the Cmax, but IMO it would be worth a shot. You've already got some m1 cells right.. Which TS cells are you considering, the 60's in 1p? For what'd you say 2-300 amps...

Re: Headway Pack Builders thread

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. Unfortu...

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 72V ...

Re: Headway Battery Rust Issue

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?

Re: Zivan Charger:What kind of plug is this?

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.

Zivan Charger:What kind of plug is this?

I was told it was an anderson powerpole but after comparing it to a powerpole it does not appear to be one. Can somebody tel...

Re: 36v20AH Lifepo4 for $312 !!! total

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 pack. I...

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 equall...

Re: Even Newer 4 to 24-cell Battery Management System (BMS)

So I'm still really torn on what would be the ideal charger to match with this BMS. If I order a Zivan I want to make sure I'm using the best possible combination. Would an constant current constant voltage curve or IUa curve of say 15Amps with a voltage of 87v (24 Cells) be the best? Or would it be...

Re: Power supply?

So is there anything special about the 10 Ohm 10W resistor. That would draw 500mA from the 5V line and use 2.5Watts right?

Would it work with a 1KOhm 5Watt power resistor which would just drawn 5mA? I have a couple spare of those but no 10 Ohm resistors.

Re: Even Newer 4 to 24-cell Battery Management System (BMS)

A quick question about transistors.

I have a transistor labeled FAN431 and another labeled KSA931 which are not in the schematic. Do I have the following right.

FAN431 = LM431 = U102
KSA931 = BD136 = Q101

And my Power MOSFET Transistor = Q4

Do I have that right?

Re: The Zivan NG1 revealed

Ahh I think I've got it now. I'll get a 72v NG1 if I can find one. The only problem being the charging curve. How much does Zivan charge for a IUa curve chip? I'm assuming that you can order one and install it yourself. I'm interested in what you've found out about re-chipping.
