So it won't work with my VRLA batteries with six sides? 

Hi Guys,

I received my 2 HA-02's yesterday (Thanks @Chris-R, Great service). I've got 8x102Ah's in two strings. Should I connect one balancer to all the batteries (like in the manual) and keep one for spare or should I connect one HA-02 per string?

One per string.  I have pretty much the same setup and they work wonders!

Would also go for one per string

Great. That was the plan initially when I ordered them but saw the Chinglish manual stated otherwise.

I'm going to install a small voltmeter to each of the batteries as well. Hopefully they will still arrive today then I can install tonight. I cannot believe what difference the Extra 100(ish) Ah is doing to my system. Everything is just smoother.

What should I do with the 2 sides issue though? should I order another HA-02? then I'll have one HA-02 for every two sides of my batteries. I've got the same problem as @Chris Hobson, my batteries all have 6 sides. 

HA-02 for that is overkill, If need be, an HA-01 will suffice for balancing 2 banks, yet the two banks are coupled togeter in Parrallel, so no chance of the two bank going out of balance if that is your actual setup

So it won't work with my VRLA batteries with six sides? Fortunately the manual's English bears no relationship to the unit's effectiveness. Chinglish does provide a bit of mirth but one must bear in mind that English is a difficult language to learn and China has only recently been thrust into the international arena. My brother teaches English in Lanzhou, which is in the middle of the country on the old Silk Route. It is a city of just under 4 million people and to date the only Westerners he has seen is my sister-in-law and a colleague from the school he teaches at. 

LOL. I'm sure one HA-02 per string is more than enough to equalise @Riaanh but we still have to problem of our batteries having six sides and the HA02 only compensating for two sides. The Chinglish manual clearly explains it.

I'm lost. What do you mean with the HA02 only compensating for two sides?

Bahahaha. Bit of sarcasm there. Get it? Six sides? top side, bottomside, leftside, rightside, etc? facepalm!! Aaaaah forget it!

I was pretty sure that's what Chris also meant, but since you also got excited about it, I thought I'm missing something. Technically the HA-02 only compensates for 1 side then.  

Sh@t. So I need 4 more?

If you decide to connect one HA-02 only, fuse all connections between batteries.

 

Never tie batteries together as in the diagram below - refer to the document I've uploaded regarding one string or parallel strings.

2 balancers for 2 strings will work perfectly. The 2 strings connected to a busbar cannot go out of balance and hence the 3rd balancer will be wasted. A good KWV would be a much better way of spending the extra boodle

Hi guys,

I installed the balancers and voltmeters last night after work. Wiring is starting to look like a spaghetti warehouse but seeing that my whole installation has to move soon i figured to just get it installed and working and do the tidying up later. This morning all batteries was on 13.8v and if I check through my S60's FLIR they're all the same temperature as well so I'm very happy with the outcome. The balancers are a must have, especcially when your batteries aren't matched perfectly. Excuse the crooked line of the meters. I cut a piece of trunking to house them. Everything is going to be redone soon.
I'm actually thinking of upgrading to an infinisolar so if anyone knows about someone in the market for a 5kva axpert, let me know. Maybe the lotto comes my way and i can upgrade to the blue stuff. [emoji12] Not likely[emoji85]

@Czauto, do the voltmeters have presets which can be used to calibrate them? I've bought 4 meters about 2 years ago, but unfortunately they did not have the option to be calibrated - lately most of them do. Back then I've connected all of them to a variable bench power supply all at the same time and varied the voltage and there was almost 1.5V difference between the meter with the lowest reading and the meter with the highest reading - needless to say, they are still lying somewhere in a box waiting to either be modified or scrapped.  

Maybe a bit too late now, but always a good idea to connect them all at the same time to a variable power supply and add a calibrated multimeter or oscilloscope in the mix and calibrate the meters before you install and connect them to the batteries. Even if you don't have a calibrated multimeter or oscilloscope, it is still better to get all of them to give the same reading when connected to the same source, that way you know that when they are connected to the batteries, you can actually trust their readings, even though it might not be spot-on they will all read the same amount too low or too high.

I connected them simultaneously to the same powersource to check them. They all showed exactly the same and I confirmed this with my digital voltmeter. This is only for reference though. The balancers should do their work but I can now clearly see what batteries suffer under load. They did cost R34 a piece so I did not expect much more from them. It looks cool in the dark though. LOL. My son calls it my High tech wall of Shite

@Czauto We need some pictoral evidence to support your son's view

I think I must build a set of voltmeters like that. My system is working so well now, there is nothing left to fiddle with! It might make a nice arduino project. 

I'm just waiting for some relays and contactors to automate my loads even more. Watch this space. I've found some very nice items but i want to see it first then i'll keep you posted

Hope you don’t mind me resurrecting this thread.

Some questions to do with connecting the HA-02 battery balancers.
We have 3 banks of 8 Trojan T105(6V) Batteries and 3 HA-02 balancers to connect.
1. Do we connect 1x HA-02 to one bank. For example the first pair from the HA-02 will go to battery 1 and then be connected in parallel to battery 2.

or

2. Do we connect 1x HA-02 to 2 banks. For example the first pair from the HA-02 will go to battery 1 in bank 1 and then be connected in parallel to battery 1 in bank 2

Do we only fuse the positive wire to each battery?

Connect one HA-02 per string

i.e. wire pair A battery 1&2

      wire pair B battery 3&4

 wire pair C battery 5&6

      wire pair D battery 7&8.

Because the positive and negative ends of each string are connected each string will be in balance with the next one. The HA-02 will ensure that each battery in an individual string is balanced. So with a little help from physics battery 3 on the first string will be within 20mV of battery 2 of the third string in spite of no balancer across the individual strings.

 

 

 

 

 

Thanks Chris

Will be connecting them this weekend.

Am I missing something? 

Started connecting the HA-02 ( wire pair A to battery 1&2)

Connected Battery 1 without any problems.

However connecting battery 2 to wire pair A is a problem. Connecting the negative of the HA-02 to battery 2 caused the cable to burn off.

The positive blows the fuse immediately.

This is how to connect it.
