(4PCS) 3.2V 280AH LiFePO4 LITHIUM IRON PHOSPHATE BATTERY CELLS BOAT RV SOLAR

Description

Brand new grade "A" REPT
3.2V, 280Ah, LiFePo4 Battery cells (4 pcs.)
with four copper busbars
and eight stainless steel M6 nuts.
REPT cells produced by the one of the leading manufecturers- RUIPU Energy Co., LTD.
Constant discharge current up to 1C (280A)
4000+ discharge cycles (80% discharge)
Equivalent to the capacity of 2 regular 280 Ah lead-acid batteries
LiFePo4 battery technology offers much longer lifespans than lead-acid batteries, while offering more safeguards than traditional lithium-ion batteries. This translates into reliable cost savings in the long-run.
Other advantages of LiFePO4 batteries:
Much lower weight
Maintain constant voltage throughout discharge cycle
Low self-discharge (0.02V/month)
Safe for indoor use
Four cells in series connection form 12.8V 280Ah battery
It is
necessary
to add a BMS circuit board
Please do not hesitate to ask should you have any technical questions!
The actual capacity of these cells is exceeding 290Ah, please take a look at the results of our own test on the picture.
The voltage on the cell's terminals at this moment was 2.91 V.
