After reading the LifePo4 discussion on this site for a year, I assembled a 12 cell 600AH bank using 200AH Sinopoly batteries. I took the time to balance them individually then in parallel for four weeks. These were purchased as NOS and have not been put through a complete cycle, so should have the estimated 2000-3000 cycles left.

In the process, we have purchased a newer sailboat, and it has 8 brand new Lifeline 31-XTs at a cost of almost $3k, with four separate solar charge controllers. It does not make sense to replace those and the solar controllers with my LifePo4 bank.

We are putting our current boat in a charter fleet, and they want SLAs on the boat, so I am selling the LifePo4s.

If purchased as a set, I will include the balancers, copper bus bars, and custom aluminum frame and compression package. Cost for entire set is $2,000 plus shipping.

Wow that's a hell of a deal . I already have a 600ah sinoploy bank . Hmmm do I need a second bank .

I think you just might! Yeah, that's less than what I have in them. I purchased them from a company that was working with a California university on an electric car project, but had about 40 of these batteries that were not used. I was really looking forward to seeing how they acted in real life use, after having spent so much time reading everyone's input and success stories.

O yes these batteries are awesome ours have been in use for over three years steady . No noticeable loss of capacity . I will never have lead on the again ! Hmmm maybe I could use a second bank ��

What is the physical size of the battery bank please??

Ooh, that is intriguing. What are the dimensions of the aluminum frame? And do you have any idea what shipping might cost to Maryland?

SVFairIsle · 13-02-2018, 15:13

The actual size is around 18" x 16". Including the all-thread that is used to compress, it may be around 21" long. I used 3/4 x 6" oak attached to the aluminum to make the battery box.

The batteries themselves are are about 16.25" by 14.25".

The think the frame is around 24" x 16". I fiberglassed some tabs on to some stringers, and suspended the span. The alumuinum is 3" structural angle. I am 225 lbs and I stood on the span with no flex. I think the batteries are right around 150lbs, so 75 lbs for each box. I would use that figure for shipping.

I received the batteries in an oversized box filled with some type of material used to ship batteries, approved by fedex. I will use the same material in two shipments of six batteries each, and will ship the frame and all other components in a separate box.

I also have a still in box/never installed Freedom 3012 3000 watt inverter 150 amp battery charger and corresponding battery monitor that can be programmed to charge the lithiums at the appropriate voltages.

....

how tall?

SVFairIsle · 13-02-2018, 15:44

The batteries are 11" tall. If used, the aluminum would add another 1/4". I am not at the boat, but the copper battery connectors arch probably about 1/2" at the height of the arc. With bars, washers, lock washers and balancers on the terminal, I would think about 12-12.5" tall.

By “balancers” do you mean BMS probes? Regardless, I am very interested. Could you give me a shipping estimate to zip code 33426. I have access to a loading dock and forklift for freight shipments.
