Hyperion EOS 1420i NET3 14s Balance Charger...

[cwah]

I just received my second hyperion for dual balance charging.

The problem is that in the box there is no network cable? Do you know where I can find one? Would this one work?

Also, the second hyperion is not recognized by my computer, I don't know why. The software recognize the first hyperion but not the second. They are however both have the relevant "COM" port assigned.

you have to do the initial setup to assign a serial number to the new one.. read the ECDS manual. Also, I Wouldn't waste your time with the network cable.. I tried using it once and I broke one of my chargers. It's an easy way to make a short circuit and ruin a charger. But if you want the cable, it's the same network cable they use on all their chargers... pushing the buttons at the same time on each charger is very easy.

Thanks Hillzofvalp, I've been to the manual and it is written:
"When you connect two or more chargers, you MUST go through this procedure. This applies whether or not you choose to pair them.

Connect one charger only, start the program and press Yes on the questions about changing serial ID
Unplug the charger, close the program.
Plug in the second charger, start the program and again, press Yes on the questions.
Unplug the second charger, close the program
(repeat if you have more chargers)
Plug in all chargers and start the program."

So I connected only 1 hyperion but I don't see how I can change the serial ID:


Any idea where I can find this serial ID?

CWAH if you dont mind voiding your warranty try going the bluetooth serial route. its not a difficult hack and means you can connect 2 or more hyperions to a laptop without the worries of blowing any of them up or the laptop. mine works great If you follow the guide from burgerman on wheelchairdriver website you will only have spent £10 (5 per charger) and half a solution that works remotely.

anyway something to think about.

[cwah]

Finally made it work. I didn't install the software update... Shame on me

Whereswally, how does the bluetooth serial route work? I don't even know how I can connect 2 hyperion together?

ps: Do I need the network cable (or bluetooth) in order to sync balance/charge my lipo? Can't I just use my computer usb for that?

[cwah]

I'm now using my hyperion for a double charge of my 20s8ah lipo:


I thought having 2 hyperions would be much simpler but actually this is really annoying.

I have to plug 2 main cables and 4 balancer in order to connect it to the hyperion. They go to the program and select individually each of them for charge.

And I don't even have an unified view of the charge!!

Took me a while to find my own post, I did a write up of the install I did some useful pics and links for you Cwah . Congrats on doing it with the cables

[cwah]

Thanks whereswally. I think the bluetooth connection should be quite practical.

But first, I'm looking for a way to simplify the balance charge of my 20s.

Do you know if there a faster way to balance/charge everything at once than what I'm doing now?

[cwah]

I'm about to buy the network cable in order to simplify the balance charge process:

Why would that broke the power supply? Not sure to understand.

Gary's boards and harnesses work great for a "one plug" charging and BMS replacement solution for my 12s8p (44.4v) 40Ah LiPo pack. I use his boards and 2 sets of harnesses and 2 Hyperion 1420i chargers... one set for home and the other set for for the office. After my long commutes to and from work I just connect the one single VAL-U-LOCK connector and start the charger. After 3 hours the pack is charged and balanced and I just unplug the VAL-U-LOCK connector. Like Gary said "one plug charge and balance solution! No muss... no fuss".

The only change I made was to make longer 3.5 ft section of the harness (the one between charger and VAL-U-LOCK connector. The added length allows me to leave the batteries on the bike and still connect to them for charging. Thanks for the elegant solution Gary!

Here's my ebike & charging station at work. Notice the short section of harness that I replaced with a longer 3.5ft secton.

I don't have a specific 4s+4s+6s connection solution, but you could do that easy enough with some JST-XH connectors from Digikey, and some perf board from Radio Shack.

I did, however, finally finish the new 12s charging harness kit instructions, and have now included the new kits on my site here: http://www.tppacks.com/products.asp?cat=26. This finally completes my quest for a simple "one plug" charging and balancing solution for a typical 12s LiPo setup. In addition, cell-level low voltage protection is included, which makes this package equivalent to a full-blown 12s BMS. The only difference is that you don't have to carry around the heat-generating balancing portion. This has always been my preference, especially for LiPo setups, but the messy connection issue was alway a show stopper, for me. This single plug charge/balance solution has been sort of a miniture holy grail quest for me, and I'm happy that it is finally over. I've now converted over both 12s3p packs on my bike, and have two new harnesses for my two 1420s.

Very Nice. May I ask where did you get the connectors and more importantly the wire sleeving from?

Blackssr:

Interesting you got a 3ft balance harness to work. I could not get the balancing wires longer than 12 inches without getting a connection error. Do you have a secret to getting the long balance wires to work?

Barry

[hillzofvalp]

I have a 5-6ft harness for 20S.. made with a parallel cable. 28AWG. works.

hate balance charging though.. putting in bms sometime soon hopefully

...

Why hate balance charging?

[hillzofvalp]

because I can't leave my balance charging setup locked up in the parking garage beneath my apartment.... because it's too sketchy/dangerous and I can't lock it in any way. So I have to carry my 70lb bike up the stairs every day. Looking to do 90%SOC bulk charges soon with bms batter charger until I get linear bms going with telemetry and delta q

Also, the charge port on my bike is not weather proof.. getting rid of it and having simple positive negative input will make it water proof and free up some hassle in the triangle enclosure

Hi Barry,
I'm the one who made that 3.5 feet balance/charge harness ...not Blacssr. I made 2 of them (1 for home and 1 for office). I'm not sure why you're getting a connection error. Try using a multi-meter to check continuity and make sure you have very low resistance in each balance lead. And make sure you use good quality wire and connector pins. I used 18 guage wires for the balance leads and 14 guage soft Noodle wire for the thick black and red.

You know come to think of it... the only time I get errors from the charger is because of a connector pin that isn't making contact. Make sure ALL PINS are pushed into the connector housing and making contact. i"ve thought about putting some hot glue on the wire end of the connector to keep those pins from sliding out.

Very Nice. May I ask where did you get the connectors and more importantly the wire sleeving from?

Thanks Blackssr,
I got the 18-pin VAL-U-LOCK connectors, the 8-pin JST-XH connectors, and their appropriate pins from Digikey.
And I got the 18 guage balance wires, 14 guage main charge wires, and the plastic mesh wire sleeves from a local electronics components store called ORVAC.

The trick with making the mesh sleeves look neat... I just folded 1-inch of the ends of he plastic wire mesh sleeves over itself and wrapped it with electrical tape.

Any chance you would have those digikey part numbers handy?

Thanks in advance.

Also, Slightly off topic, how do you prevent the arcing when plugging the batteries. My anderson connector is taking a beating. I am 20AH 44 Volt Lipo (12S4P) Sorry for the all the questions. New guy here. .

Usually you just need to turn on the charger and wait a few seconds for the caps to charge up before plugging the battery to the charger. If you're asking about the spark when connecting the battery to the controller then research 'precharge resistor'

[cwah]

Just had the answer from the manufacturer. For all of you that are thinking about buying 2 hyperions for bulk charge,
the only way to sync charge is like this:


It's not possible to series your hyperion to simplify the charging process, each hyperion needs to have its own balance plugs and battery plug

[hillzofvalp]

Most of us might just already know this... But to clarify---net cable just let's you use one hand to initiate the charging. If u like using one hand, then it's worth risking damaging yr charger. If you don't mind using both hands at once (for the same amount of time), you could save yourself a mistake

[cwah]

Why is there a risk of damaging the charger with the net cable?

[hillzofvalp]

if you happen to have the packs in series or you plug both chargers into a computer a certain way, you fail

[cwah]

hmm... already purchased my net cable. Don't see much difference anyway.. thanks for the warning

Hey guys, i found this video on youtube about connecting 2 6s packs to charge at 12s. They say that there is a special sequence to plug in the balance taps in the charger. The high side goes to slot B and the low goes to slot A or whatever that means???i'm not sure. They say that if this sequence is not respected, there is a chance that the pack can not balance properly. Any of you guys ever hear of this? Here is the link http://www.youtube.com/watch?v=7I76y8eizm0&feature=related

[999zip999]

I believe the A port is for 1-6 ( 24v) the B port 7-12 another 24v for the high side for 48v. This 1420 is hard to land on the right screen. Yes I'm straring at it. Damm screens. and can't reset it unless I unpluged It ?
