Large capacity lithium cell LiFePO4/LiFeYPO4 - 3.2V/700Ah
Professional lithium cell for energy storage and other high power
applications. Produced by the Winston Battery company
(formerly Thunder-Sky) – product codes WB-LYP700AHA, TS-LFP700AHA,
TS-LYP700AHA. The large capacity monolithic cell – consists of
a single cell structure.
Store easily large amounts of electric energy
the most safe and secure lithium technology.
High energy efficiency
: minimal loss of energy
during the charge and discharge cycle.
Long time reliable performance
over many years.
The cells have very high internal stability and well work for
many years and decades.
High cycle life
: the cell support thousands of
cycles 3000, 5000, 7000, or more.
Reduced toxic risks
: no acid electrolyte, no
dangerous gasses during normal operation, low fire risks
High power applications
: extreme power rating
for short time discharge current - up to 10C (thousands of
High power rating
for deep discharge cycles –
support discharge currents of 3C continuously.
Minimal self-discharge rate
- no memory effect
– the energy charged to the cell will stay for many months. The
cell can be charged at any state of discharge.
The high capacity cells are especially suitable for
making battery banks
. It is very easy to make a battery
bank of 12V, 24V or 48V
. The large capacity
cells reduce the need for cabling and make the installation very
Basic technical specification
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)
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 260Ah cell is 130A.
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
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.
