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

[deVries]

I'll also provide options for some pre-made harnesses. The 1420s also come with a couple balancing adapters, for most popular RC pack brands. When I get the site updated, I'll start a thread in the "For Sale" section, which will include a way to get the discount coupon.

I found these for 179.95 w/free shipping, but I'm waiting for your "ES coupon" instead.

Looking forward to some news about the Hyperion ESC with the higher HV. Anything new on that, or when these HV ESC's will be available?

Thanks for all the electronics gifts you provide ES...

Gary, thank you for your review. I have been curious about this charger since it came out. Good infos here.

I bought an iCharger 1010b+ because it would do 10s in a serial string, and i thought that was pretty cool, but the convenience stops when i want to go over 36v. 14s gives me the capability to do 51.8v nominal on my upcoming build, which i think is a pretty damn good voltage for an eBike. I think most people would generally be happy at that voltage.

I think these will be VERY popular soon. Who wants to constantly break apart parallel sections of the battery pack to balance charge? what a PITA.... for higher voltage guys, it will mean a hell of a lot less serial disconnecting.. unless you're like.. drbass or steveo

...AND

This 1420 can be ganged for up to 28s (14+14) with full battery charge management.

I've been waiting for a charger like this. I was looking hard at the FMA PL8. The PL8 has some advantages (more than twice the power, much higher balance current) but it is hard to match the convenience of charging without having to reconfigure the packs. I can picture myself making a mistake one time and poof!

The lower balance current of the 1420 isn't such a big deal when you consider the packs don't have to be paralleled to charge

Two of these and a 24V/60A supply would be a very nice setup.

BTW. In Canada, this charger can be purchased from RCFlightStore for $180CDN shipped last time I checked...

[hydro-one]

two of these and two 24v/30 amps supplies you mean..... so you can charge a string of up to 28s without any KFF?

I assumed an isolated supply would be required for each one?

To do a sync charge with two 14s packs, they can't be connected in series, so something is not isolated somewhere.

I have two of these, each setup to charge 1/2 of the 24s3p setup on my bike. I leave the two 12s3p packs connected in series, on the bike. I use two S-350-24 MeanWell supplies in parallel, with each 1420i charger, so that each can max out at 550W. This basically lets me balance charge a full 100V and about 11-12A, max.

Luke said that the iCharger's are isolated so you can use multiple iCharger's without serial disconnecting.

[damonjackson_spl]

Let me know if this is a dumb question?!?!?

If you have multible built li-po packs 6S, 10S and 14S, say a 22v system for a friction drive, a 36v hub motor drive and a 48v system for a hi powered direct RC drive

say one day you want to charge the 14S pack, you obviously need a 48v supply (meanwell SP-500-48 or similar)

but if you want to charge a 6S pack later on during the week do you need to have another power supply of 24v to do the charger to do that pack?

just sounds expensive having to buy 3 meanwell power supplies to charge the different voltage packs if you dont want to break down the different voltage packs to the same voltage and use the one charging supply system?

or am I missing something?

cheers

You seem to be missing the point of this thread which is using an RC Charger (in this case the Hyperion EOS 1420i NET3 14s Charger) to charge your pack(s). You could use it (up to 14s) with one small 12v PS but that would be slower than the method Gary (two paralleled 27v PS's) is using.

Very interesting, but i don't understand how that works at all. Care to explain?
Seems like 1 iCharger would be seeing double the voltage and that could be a problem

[AussieJester]

Totally... The Hyperion isn't a AC powered charger i.e you can't plug it into the mains
(those new wall plugs in Tassie Houses...you may have alight running off one now )
The meanwel is only being used to power the Hyperion, its an RC charger, it will charge
lipos, nicads, a123s etc etc of all combination's, you need ONE psu to power the Hyperion, simply
set appropriate settings on the Hyperion for whatever pack you wish to charger. Gary is using
a pair of 24v meanwels in paralel to power his Hyperion, as Mitch has said above, you could use a 12v PC PSU
if you wished but it would take longer to charge, Mr Goodrum is about the fast charging hence the 2x 24v PSU.

[neptronix]

ha, i think this talk of using meanwells AS chargers has got some people confused..

[damonjackson_spl]

ok so the power supply can be a meanwell 24 or 48 doesnt really matter, and we can tell the hyperion what to charge 22v, 48v etc so power supply doesnt really matter, other than charge time?

[AussieJester]

yes...except for the meanwel having to being under 27v to power the hyperion...

The power supply can be whatever power supply you chose. I have a radio shack one i use for example for my icharger, i could use it for a hyperion, tunirgy charger, whatever.

If the hyperion takes 24v input , you can use a 24v power supply.

Most RC chargers want 10-20v as far as i know, though.

http://www.empirerc.com/hyperion-eos-1420i-net3-charger-1s-14s-20a-max-550w-p-5669.html

A brand-new power supply technology is boosting the charging power to 550W when the input voltage is between 24V and 28V. Of course you can still operate the EOS 1420i NET3 on the typical 12V also but with less overall wattage.

Luke said that the iCharger's are isolated so you can use multiple iCharger's without serial disconnecting.

I'm sorry, I can't explain how it works other than that isolated inputs are the key.

To do a sync charge with two 14s packs, they can't be connected in series, so something is not isolated somewhere.

I have two of these, each setup to charge 1/2 of the 24s3p setup on my bike. I leave the two 12s3p packs connected in series, on the bike.

-- Gary

For example I'm pretty sure the reason Gary can leave his 24s pack connected is that the MeanWell supplies are isolated. So I think I know why it works but if you want to know how it works you need to ask Gary, Luke, Richard etc...

[GGoodrum]

Yes, Mitch is right. The MWs have isolated outputs, so the chargers can then be isolated. In the end, it is all about how much charge power you can get to the pack(s) at one time. "Sync" charging is somewhat meaningless, in my mind, unless you aren't charging at all, but just want to use the balancer mode to balance all the cells to the same point. You can do the same thing while charging the cells, and the cells end up charged and balanced to the same point anyway, so "sync" charging doesn't get you anything, in my opinion.

Having to use separate supplies, to power each charger, is a non-issue, in my case, because in order to get the full 550W out of the 1420i units, you need a supply that can put out 650-700W, and they need to be about 26-28V. By far the cheapest/most readily available MW options are the SP-320-24 and S-350-24 models. For bulk charging my 24s3p setup I've been using four S-350-24s, wired in series. Now, with the Hyperion chargers, I just split the four into two pairs, and wired them in parallel so that I have two setups that can each put out about 26A at 27V. Each of these are then used to drive a 1420i.

Just to be sure:

- You are running 2 hyperion 1420i chargers on separate isolated power supplies (MW in parallel).
- You can charge your 2 x 12s subpacks simultaneously (each on 1 charger) while the whole pack is in series (24s).
- Should you connect the "sync" networking cable between the 2 chargers this would create a short ?

I also don't view the "sync" feature as that important but want to know if it would still work if your chargers are on separate isolated supplies.

[GGoodrum]

Just to be sure:

Yes, that is right. Two MWs per 1420i.

- You can charge your 2 x 12s subpacks simultaneously (each on 1 charger) while the whole pack is in series (24s).

Yes, they are basically permanently connected in series on the bike. I bring out one 18-pin AMP VAL-U-LOK connector for each 12s3p pack. Each of these connectors use 14-pins for the balance wires, and two-each for the main charge + and - connections. All I do is plug in the MeanWells, and then plug the two 18-pin plugs, one from each 1420i, hit start on both chargers, and that's it.

- Should you connect the "sync" networking cable between the 2 chargers this would create a short ?

Yes, magic smoke will be forthcoming.

I also don't view the "sync" feature as that important but want to know if it would still work if your chargers are on separate isolated supplies.

It would work if I wanted to break the series connection between the two 12s3p pack, but what's the point? I can now basically charge my whole 24s3p setup at 11-12A and end up with balanced cells, every time. No muss, no fuss.

[El_Steak]

This is a great solution, at long last I can permanently wire and stop fiddling with those serial-to-parallel adapters.

I almost bought and additional 3 iChargers 206b last week (4 total) so I could accomplish the same thing. I much prefer this solution with just 2 chargers to deal with.

I'll see how your drop shipment experiment goes with Miles and if it works OK, I'll buy 2 from you. If not, I can always source them locally in Canada.

Thanks for taking the time to answer our questions.

Maybe one last improvement suggestion, you could swap the 18 pins VAL-U-LOK connectors for the 20 pins variant and use the additional 2 pins on each connector to wire-in the charger's temp sensor inside your pack. Just an extra safety measure available for free.

[GGoodrum]

It works but they apparently ship via USPS' international Parcel Post option, rather than international Priority Mail, so it could take a bit longer, and it seems pricey, at that (around $35...). I'm still looking into this, so we'll see. Ideally, I'd like them to use Priority Mail and use the flat-rate PM boxes. Otherwise, it might be cheaper to just buy it locally

The 1420i units do have a temp input, but you have to order the sensor separately. I have never used them, as I don't ever have a pack get above room temperature. If cells have a problem, there's plenty of other safeguards that will stop the charge process.

Let me rephrase:

what charge rate could I see when I hook up my 1420i to my 430w psu that has a 32A net max on the 3 12v rails combined (16A individually but they are all hooked up at one)? this is for a 7s2p or 6s2p a123 26650 pack.

Also, how I limit the current coming out of the psu to the hyperion to 10A? (banana posts are rated at 10A, so if I did go higher I would have to rewire)

I can get 384W out of my 3 12V rails combined. MAX of 32A. Other specs here:

In both cases, the charger should max out at 20A. Basically, what you do is take 550W and divide it by the pack voltage the charger will see. For a 7s LiFoPO4 pack, that will be about 25V, and 550/25=22A. The max the charger will do is 20A

Also, how I limit the current coming out of the psu to the hyperion to 10A? (banana posts are rated at 10A, so if I did go higher I would have to rewire)

There's a setup item that lets you limit the input current, but I wouldn't worry at all about putting 20A through a banana post, any banana post.

I can get 384W out of my 3 12V rails combined. MAX of 32A. Other specs here:

You need to have higher than 12V in order to get the 1420i chargers to max out. If they are isolated, maybe you could put two in series.

International shipping update...

It took 14 days for the international Parcel Post shipment to finally reach Miles. This was definitely worst case, sue to the weather, and to the holidays, but I'm still trying to convince them to not only use Priority Mail, but more importantly, use the flat-rate packaging , which cuts the rates significantly.

[johnrobholmes]

I got a few of these chargers for myself, and they are just what we need for a high quality and reliable charger! Much more precise than the current ebike charging kits, and just a bit more hassle to use. If only we could have something that was plug and play for the dumber users that aren't hobbyists.
