Hi

Checking my battery voltage this morning - I have a HA-02 balancer in circuit:

13.1 / 13.1 / 13.1 /13.3

Is a .2 volt difference within the operating specs of the HA-02?

The balancer has been connected for 2 weeks now.

New batteries.  Used as a UPS, so they mostly sit on float - hence the lower than average storage voltage.

I must say I don't "hear" my HA-02's, maybe the bigger the imbalance, the harder they work, i.e. emit noise. or i'm going (high pitch tone) deaf, seeing the wife always tells me!😜

As I have 8 Trojan's & a BMV, I only measure my midpoint, and after almost 3 years, it's still @ 55 mV. In your case it's 200 mV.

Maybe it will quieten down, once your batteries are equalised better?

Mine made a high-pitched sound constantly till it went up in smoke. Like Badly. Got a amp pull/spike and took the hit because the battery didn't have all the supply to give. Just run a fuse on it on every channel that yours don't go up in smoke like mine. It takes day's to get rid of that smell.

Surely the he HA-02 has been connected long enough to balance the batteries?

The sound hasn't got any quieter since it was hooked up.

Gerlach, yes, I have 10A automotive fuses on each line.

It's the battery on the far negative side that is slightly up.  It's only 200mV, but I was hoping it would be better.

Good afternoon

I have 12 x 250 ah Gel batteries on a 48 volt Axpert 2 x 5Kv MKS parallel inverters with 6kw of solar.

Currently i have a HA-02 on each of the three banks of batteries, what would the correct wiring of these batteries with balancer 

Victron are suggesting that you parallel the series bridging of the batteries would this improve the charging and balancing of batteries
