URB6450 | 6.4V


This batteries is a Lithium Iron Phosphate (LiFePO4) chemistry targeting applications typically served by Lead Acid batteries (SLA), providing enhanced cycle life, 100% depth of discharge cycling, and longer service life (less associated maintenance).


Technology Lithium ion (Rechargeable)
Lithium - LiFePO4 (Lead-Acid Replacement)
Nominal Voltage 6.4V
Average Voltage : 5.0V - 7.2V
Nominal Capacity 4500mAh
Energy 29Wh
Volumetric Energy Density 88Wh/l
Gravimetric Energy Density 81Wh/kg
Charge Mode Connect the battery to a DC power source using correct polarity and apply a maximum voltage of 7.2V. Limit the current to the recommended rate of 900mA and hold 7.2V until the current declines to 90mA. Maximum charge rate is 4.5A.
Alternatively, you may apply a maximum charge voltage of 6.8V (limiting the current to 900mA) and hold indefinitely to maintain the battery in a continuous standby state-of-charge of between 70-90%.V
Continuous discharge current (max) 9A
Pulsed discharge current (max) 30A
Maximum pulse width of between 5ms and 20ms.
Protections Overcharge: 3.90V (per cell)
