Good morning Everyone,
Quite new here, and I would like to ask for some advice / opinion from the community.
I am in the process setting up an off grid solar system. I am planning to use 32 pieces of 280 Ah EVE batteries, with two banks of 16 pieces. I am planning to use Seplos BMS system, mainly because they promise compatibility with several ready-made battery systems. ( https://www.seplos.com/sale-1370706...ttery-smart-monitoring-management-system.html )
My current to be battery supplier is Amy from Shenzhen Qishou Technology Limited, amy@qisocell.com . , and the product is “US EU!!Brand New EVE brand 280AH 280K 6000 cycles lifepo4 battery”. After some iterations we agreed upon $104 per piece price plus $656 for shipment to Hungary . The package would include the bus bars . She promised the this price will include all tax and VAT to my country.
This package seemed promising to me. But after following the advice from this forum I asked for “ spread sheet form EVE that shows the capacity, all 3 volt readings and all 3 ohm readings for the cells including their case ID”. The price changed to 128 / pcs.
I am wondering wether the batteries in the original offer were not grade A, and requesting a test data She has to deliver the real grade A cells, or do they really have further costs ( 25% !! ) getting it from EVE ?
Any advice appreciated,
Regards, George
