For Sale, Surrette/Rolls 4KS25PS 1350Ah 4V batteries
I have twelve Surrette/Rolls 4KS25PS batteries for sale. They are used and have run my house for 10 years, but still cycle well and just keep on ticking. I have switched over to LFP batteries, so am offering the Surrettes for sale. Each battery is 1350Ah at 4V, 20hr rating. I have been running them in series for a 1350Ah, 48V bank. Total power is about 64kwh, and I use them down to 50% SOC. Charging has been via solar with a back up generator (off-grid installation). All indications are that they have plenty of life left in them, but I can't make any guarantees. Surrette warrants them for 10 years (expired), and says the design life is 15 years. So according to them, they should be good for another 5 years.
Also included is a BWT watering system which greatly simplifies maintenance.
As 4V cells, they can be configured for 12V, 24V, or 48V - your choice. My preference is to sell them all together, but minimum purchase is 3 batteries for a 12V system. New these are $1300 each. I'm offering them for $200 ea, or $2000 for all 12 of them.
I can remove them from the house and have a forklift to move and load them, but you will have to sort out transportation. I might be able to help, but it would be in addition to the purchase. They are VERY heavy at 315 lbs each, so multiple trips in a pickup truck. Located in east central Vermont. Picture and spec sheet attached below.
