HINT: Do you need 4 cells, 8 cells or 12 cells?
Or multiples of 4 cells? Consider buying the 12V block batteries to get the pack of 4 cells. Check details at the GWL/Blog
. See the offer for the 12V block batteries
. You may also wish to buy the 12V batteries if the individual cells are not on stock
This is the original 143mm (145mm) size 90Ah cell. Please note that Winston Battery (ThunderSky) is producing other dimensions as well. We can deliver the other sizes if specifically requested by customer for larger order quantities.
Nominal voltage of the cell is 3,2 V and the operational voltage is 2,8 V - 3,8 V.
The maximum charging voltage for initial charge is 4 V.
Recommended subsequent charging is to 3.8 V.
The minimum voltage is 2.5 V.
Maximum discharge current is 3C continously.
Operating temperature -45°C up to 85°C (discharging)
These battery cells are suitable for all traction applications
including electric vehicles. Fully complies also for stationary applications
- such as energy storage.
There is no Selfdischarging effect.
Can be recharged at any state of discharge - no memory effect
LiFePO4 is a very safe technology,
not spontaneous combustion, does not react with moisture or with oxygen.
All goods we supply is new direct from the manufacturer.
The batteries are charged conservation.
To be able to use it must first be charged with a low current.
The first charge should not exceed 0.5 C - eg for 90Ah cell is 45A.
FAQ: Initial charging information
For initial charging multiple cells, must be connected in parallel and the charger outputs should be connected to both ends of the parallel rows of cells, exactly as it is described here:
FAQ: The initial charging of the number of cells
Please see practical examples of installing cells and recomended SBM protection of operation:
the Simple Battery Management.
Example of the 16 cells in series with protection module SBM16.
Check recommended accessories:
the terminal connectors.
Flexible terminal connector for safe connection of cells.
terminal covers for the LFP cells
They protect the terminals against dirt, damage and short-circuit.
