Thanks ! that was completely out of necessity ... and the great advice from everyone here on the forum who encouraged me to put most of them directly into service and let the solar system doing the balancing . Thankfully all except one cell was within .008 of a volt which was great . The old...

Thanks to everyone for the advice , I had the 9 banks all wired up on Sunday evening and made the switch over from the old batteries to the new Lifepo4 batteries , I decided to run the generator the first night as I would have done anyways with the old set , to give them a decent charge before...

Unfortunately I don't have the ability to test individual cells

Thanks, looking back at the solar journey of the past 14 years I really wish I had done a build thread or blog but unfortunately I have so many projects on the property that I never had time to put something like that together . I'll try to post some pics over the next few days . Good luck...

Thanks for the advice , never thought of that !

Amy had sent a few videos before shipping showing voltage and internal resistance of all the cells , I don't remember seeing one that was that much different , I'm going to take another look at the videos to see if I spot anything . Going to take your suggestion and set up the 9 banks of 16S...

I have 10 BMS's to connect .

Just finished checking the voltage on all the cells , 159 of them are between 3.288 to 3.296 volts , one is 3.346 ? Haven't checked IR yet . When you say to set the absorb time a little longer , what would you suggest ?

I received all 80 boxes and if I was in the States or Canada I probably would refused the delivery . The plastic pallets that the boxes were packed on both collapsed and more then 20 of the boxes had damage to them . I have to say that I was very impressed with the foam packaging around the...

That's correct , worst case they may go down to 25%, my calculations have them running between 40-85 % most of the time . Trying to get the longest life out of them .

Balancing the sets the way you are suggesting would make things much easier , and also have the batteries in service much sooner . Would you suggest using the generator to supplement power to make sure I'm hitting the target voltage daily, or just let them cycle normally with the solar ?

I'm going to try and do most of the initial charging and get them as close to full with the solar and generator , system consists of 60 x 300 watt panels , 4 x outback flexmax 80 charge controllers , 4 x outback 3500 watt inverters , and a kubota 25kw generator . The tough part is going to be...

Thanks for the reply , unfortunately I don't have a choice on what's being delivered , once they arrived in Miami they were transferred to another shipping company to get them to me here in the caribbean . I'm hoping that because they were on 2 pallets that there was less of a chance of damage...

I'm finally receiving my shipment of 160 x Eve 280AH cells that I purchased from Amy. It took 3 months to get from China to Miami, Miami to Antigua, then Antigua to Barbuda and they are arriving on the cargo boat today ! I've been doing a lot of research on top balancing but I'm not finding...

Thanks for the advice . From past experience it definitely makes it easier if somethings not right or needs attention .
