QUESTION: I want to make the initial charge of all the LiFePO4 cells to the same maximal voltage level of 4.0V. How can I do that?

EDIT: This article gives the example of 4.00V charge level. The same information is to applied for charging to other voltage levels: e.g. 3.65V, 3.70V, 3.80V, 3.90V.

Remote LED signalling for the TC Chargers

The TC Chargers support signalling via Remote Dual Color LED.

• Remote LED should be dual color common cathode
• The voltage is recommended to be 3.3V
• Pins 4 for red and 5 for green leds.
• Remote LEDs, it should be totally isolated from other circuits

High Current Charging and Discharging Report for WINA Cells

High Current Charging and Discharging Report for WINA Cells

The purpose of the test is to verify the performance of the LiFePO4 cells in high current discharge and charge conditions:

1) What are the discharge characteristics for 1C to 3C currents? 2) How will the individual cells perform unde

DC Power Latching Relay 100A, Coil 12V and 48V

DC Power Latching Relay 100A, Coil 12V and 48V

High current latching relay designed for AC and DC voltage with a maximum current 100A DC (at 48VDC) or 120A AC (at 250VAC). The advantage of the lachting relay is that there is no need for continueous powering of the operating coil.
