EVE LiFePO4 280Ah 3.2v Battery Review
Thought for those interested I would give a run down of the batteries which recently landed - I will try and update with more info over time, as they are not even in the boat yet.

I have 1120Ah @ 12v which is 16 x 280 x 3.2v which were purchased on Alibaba from a supplier recommended by a friend - He has been running the same for the last year and has had zero problems with them - He also lives aboard.

Cost of batteries including shipping, duty and GST was USD $1865 whilst other upgrades to accommodate them on the boat is around USD $2000.

Purchase to delivery in Australia was 8 weeks (Lithiums have to come by boat into Australia), this would have been 6 weeks if TNT had not delivered to the wrong address, who was a mine worker and was away from home for 2 weeks.

A thorough physical inspection revealed no issues and all walls, seals and terminals are in good condition, so from that front I am very happy. I did order larger bus bars, but China being China they had to stitch me up on something - Instead of the 20mm x 4mm Busbars they gave me 20mm x 2mm and only 20 of them as well, so that was a bit annoying.

I checked the voltage of each battery and they appear very well matched with 10 @ 3.304v, 2 @ 3.303, 2 @ 3.305, 1 @ 3.302 and 1 @ 3.307.

After Paralleling them all up to create a whopping 4480Ah bank @ 3.2v I proceeded to Top end balance them - Firstly up to 3.4v, which took around 5 days and then to 3.5v and then 3.6v which I did over several hours - At 3.6v every one of the cells is reading 3.600v.

I am pretty happy with everything so far and will update as things progress.

Don't to forget the capacity. Some vendors state 280 AH and the cells only deliver 224 ah. Just pick a set of 4 cells and see what you got.

224 AH is 80% of 280 AH and any cells that come in at 224 are likely pulled from use and not new.

I have a set of 280 AH cells advertised as new but averaging 224 plus or minus. The vendor is being a pain in regards to testing. I'm asking for a partial refund.
