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

That's how fast I go up a real hill 16-19mph.

Hi
If I was on one of my regular bikes with 26 inch wheels I would get the same or faster but this is on a small wheel folding bike like a bromtom with a bafang motor, the speed is limited by the wheel size considerably and with a bafang motor much faster RPM and I will get a case of peanut butter gears in the motor.
The RPM the motor is doing when I am at 17 mph is at the limit for that motor I am quite happy with that as it is a bike mainly used when I go on the train or take it camping with my tent as it folds it fits in a very small space.
If I wanted speed I would use my mountain bike with a top speed on the flat of a little over 30mph on the flat with 20 up the good steal hill in my local town.

I order a 24v 1000w 47a. power supply 80.00 and received a 24v 500w 47a supply 40.00 on their website. How close to max. charging will the 24v 550w get me ? I have to contact seller. But might need a second 1420 for my18s and to be build 24s. If the 24v 500w will get me close to top output then I will try to have them send me one. Thanks
Geoff I have slow down I came go 22mph on the beach but 12mph is much better. But the hill is great at 18mph. Wouldn't mine a folder.







Edit: I guess my two 12v 500w adds up to 24v 1000w Opps

Hi
The folder is strictly for use when I go on a train or go camping, on a train it will fit into a small space when others with moutain bikes get left behind as there is no room,with camping some of these sites are big and going to a shop off site for me is hard I can't derive as I have epilepsy. My moutain bike even folds making it Easter to store on a train and get round public transport laws that say only folding bikes allowed.

I have a small strident/pinch sound coming from my hyperion when I bulk charge at 14A. When I reduce to 12 the noise disapear. Is it normal?

Does it sound like it's coming from the fans? I hear a high pitch buzz on one of my 1420i's from the fans around 4A whenever it ramps up the charge current. The noise goes away tho when I reach 6.5A.

Try giving it a light tap

[cwah]

Don't really know from where it's from. I'm afraid to make an explosion if I move it too much lol.

Will try a light tap

[FastDemise]

I put a folded shirt under my charger. I can hear the fans buzz in my garage through the floor.

I finally got my custom balance harness figured out for the darn Hyperion. I've been trying to get my Hyperion to charge the 8s m1 A123 packs I'm building for a buddy. Wired alligator clips to the ends of 10 balance wires. Had to hook up the main +/- of course but connect the balance leads like it was 2 separate batteries. Meaning

1 - Main Negative
2 - Cell #1
3 - Cell#2
4 - Cell#3
5 - Cell#4
**(5 and 6 are on the same lead)**
6 - Cell#4
7 - Cell#5
8 - Cell#6
9 - Cell#7
10 - Main positive (#8)

That has finally allowed the charger to start balancing the pack. Took forever to realize I had to charge in pairs. 12s treated like 2x 6s and any combination inbetween. Hope this helps someone.

Cheers ES,
Lance

Problem with my charger
I just tried to charge and noticed the TCS Cap % terminal capacity selection is not moving up as it charges, thus not shutting down the charger at a given percentage. It shows the individual cells moving up in voltage however the TSC stays at the same %. I tested it trying to stop a charge at 50% and it continued. When I shut it off and start again the % is at the higher voltage however im afraid the charger will continue to charge.(as it did)
any ideas folks? Yes, i have the TSC set at stop.

thanks

I have the same problem. It doesn't stop at the % terminal capacity but goes higher. But it goes up until a maximum and after it goes to balance mode and the voltage decrease gradually until the % terminal capacity.

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.

[hillzofvalp]

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.

[cwah]

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."
http://media.hyperion.hk/dn/pc/ecds-man ... argers.htm

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?

[whereswally606]

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?

[Barry]

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

[Alan B]

...

...

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.
