Be sure to add a 20amp fuse right at the Pos end of each wire . If anything goes wrong, you've got equalizer wires dangling across pos/neg terminals of 4 batteries that will put out 100+ amps before their BMS own would stop them. Does this stay connected or do you have to connect this periodically ?
Is there something like this for 2x24v server rack batteries in series to make a 48v ? My neighbor has such a setup and his 2 24v batteries are out of balance. They are eg4 lifepower4 or whatever 24v the lowest end one that they used to make. Thanks
It can also balance a 24 volt system and balance charge a12 volt system at the same time. To set up on 24 volt battery systems consisting of two 12 volt batteries in series. Connect one set of leads to each of the two batteries individually creating the 24 volts. Connect the two remaining sets of leads onto a single 12 volt battery. This will push or pull about 6 amps max with two lead sets connected to the individual 12 volt battery. It's a simple solution when using a 24 volt inverter, but still have 12 volt junk that needs to be plugged in. Note all batteries connected need to be of same chemistry. A 12 volt balance tap can also be achieved with 36 volt system consisting of three 12 volt batteries. Simply connect one set of leads to each of the three 12 volt batteries creating 36 volts. And the fourth set of balance leads will connect to the individual 12 volt battery. Don't expect more than 4 amps trickle charging with a single balance lead set. To create a 48 volt to 12 volt balance charging you will need two units. The 48 volt system needs to consist of for 12 volt batteries. Using two units consisting of eight balancing lead sets. Each balancer will have two of its balancing lead sets connected to the individual 12 volt battery. The remaining two sets of balancing leads from each balancer will connect to the four individual batteries of the 48 volt system . This configuration will allow a 12 volt system to push close to 3 amps to a individual 12 volt battery of the 48 volt system. As the load is balance charging the individual batteries needs. And the 48 volt system will be capable of 10 amps of push on a good day to the 12 volt system when balance charging at maximum.
As always you sold me Ian. Just ordered one.
All the question marks in my mind have been cleared thanks to you. thank you
You are most welcome
Several people that I see on fb solar pages I tell them this one is the one one that works
So, this will or will not keep 2-24V batteries ballanced? Using 2- LiTime 24v 280AH batteries...
So one you install the balancer, do you leave on all the time or take off when all are balanced?
Nope. Leave them on all the time

Thank you Ian!
How about you only have 6 12v batteries how would you wire the last two batteries?
very test. thank
