To Buy a PL8 - Accessories

[martin007]

Hello!

PL8 is an excellent battery charger.

What to buy to be able to charge gel batteries?

What cables and accessories do I have to buy?

[Burgerman]

Do you mean what do you need with the PL8?

Are we talking about on the bench?
In a chair?
24V series via Anderson?
24V series via XLR type charge connection?
12V parallel via Andersons?
How long cables?
What speed do you want to charge? (Amps?)

And do we include a power supply cable here?

You need to clarify a bit!

[martin007]

You need to clarify a bit!

Sorry.

24V series via XLR

[martin007]

Any pictures of how you connect it?

[Burgerman]

Then you will need, a profile from me, that is SAFE for XLR, and gel, since it cannot ever be set above the max allowed 12A RMS current.

And you need to buy a bag of SAFE banana connectors, like these:

Dont use different ones.

And some twin cable, that is 1.5mm sq absolute minimum if say 1 meter long or 2mm to 2.5mm if you make it longer I would use 2 or 2.5 thinwall... this type of cable:

IF you only want to charge lead, you need just a PL8v2, and a USB interface connection for the PC called a FUIM3.

Depending on what you are powering it with you will need a set of conections for that. I fitted andersons to all of my tools, batteries, power supplies, chargers, solar systems, etc.

[Burgerman]

Too expensive. And you also need a FUIM3.

[martin007]

Where do they sell it cheaper?

is it possible to charge a 2x12V pack of Sinopoly 200Ah connected in series through my joystick using PL8 but without balancing wires? How?
These are accessories that I have:

PS24V50A-BL 24 VDC 50A Power Station
SPA-XH Adapter Combo with Cables for Connecting to a PowerLab Charger
MPA-XH Adapter Combo with Deans and Cable for Connecting to a PowerLab Charger
LC08S40A-EC5-MC Cellpro PowerLab 8 v2 with EC5 input cable, 1344W, Multichemistry Battery Workstation

s it possible to charge a 2x12V pack of Sinopoly 200Ah connected in series through my joystick using PL8 but without balancing wires? How?

Lets do a little math.
The max you can put through a joystick is 12A before you melt something.

To replace say 180Ah of your new battery (90% of its capacity) will take 180 div by 12A = 15 hours at CC, plus a couple at CV. So 17 hours....

And without balance wires, connected to the PL8 you coud put SOME back but you couldnt fully charge, because one cell group will go full before the rest. So you need the balance wires connected. Unless you were to use a BMS... And we know what happens to most of those! So the answer is yes, but not very useful!

[Gnomatic]

I got this cable for the PL8, and stuck an Anderson on the end.

http://www.usastore.revolectrix.com/Pro ... ug-Cable_2

Then I made another short cable with an Anderson on one end, and an XT60 on the other. Finally, I made another short cab;e with an XT60 on one end and an XLR on the other. I connect them together with the PL8 and charge my lead brick chair through the joystick, using BM's 24v XLR MK gel preset.

Why did I make a charge cable like that? Its versatile. I can use different segments of it to charge different things.

[sin85]

but i will use the bms for charging only.
i realise that it would take long time to charge @12A but i will probably never go quite so low as 90%. this set up is temporary and simplified for middle aged uneducated carers that have problems operating a microwave.
but how i do it? hyperion for example just warns you that balancing wires are not connected and you can ignore it at your own peril.

[Burgerman]

Simple. Tell it its a 24v lead battery. With 3.55v per cell x 8 voltage. And 12A charge. And around 300thC termination.

OR...

I can do a special no balance wire, lifepo4 profile, with a 12A limit. But for a couple of reasons the lead one is best.

[sin85]

great. thanks.

[Burgerman]

Here you go...
But I cannot limit this to max 12A. So if you choose higher, you will melt something.

[sin85]

thanks again. just as i side what would happened if i were to charge them with 12A mobility charger designed around MK gels?

[sin85]

Here you go...
But I cannot limit this to max 12A. So if you choose higher, you will melt something.

i downloaded but winzip is telling me it is not a valid archive. should the pl8 software be up and running?

[Burgerman]

God knows, because I never found 2 mobility chargers that did the same thing.

But IF it charged at the correct voltage for gel, then that would be too low just, to allow the balance on the BMS to work. Unless one cell was high by a margin. And, it would be 8A which means it will take 50 percent extra charge time, and it will likely terminate too soon at about 1A and go to float, which is too low for balance or charge. So likely safe but we cant know it will do that!

E.G. the new salsa chairs charger I have, has no termination point based on current at all, other than an 8 hour cv timer. And is 29.0v. That would do your lithium no good.

[Burgerman]

Remove .zip from the file name. Thats only to fool the board. Its not a zipped file.

the charger for my optimus is 12A

Dump charger won't fit for the job . It won't restart during BMS balancing . Adjustable PSU is better .

Strongly advise you NOT to use incompetent BMS , which are set way too high to cut-off @3.85V 。 Will kill your cells in a few cycles .


There are programmable BMS , that you can buy and set over-volt-cut-off no higher than 3.60V.

Not expensive at all , with bluetooth , so you can monitor everything on you cell phone . Seperate display too .

£40 or so .

Those only have 8 hour CV and charge at 28.80V. No current sense to terminate at low current. And 27.6 float. They are not good gel chargers. If you connect one to a full battery, it STILL charges at CV for 8 hours!
