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.
The consumption of the DC contactors
Our tests show the following consumption of the DC contactors:
12V/100A model - 0.45 Amp at 13.4V 48V/200A model - 0.13 Amp at 53.5V

A simple mistake: the cable rolled up on a wheel-cable extension cordused to charge an EV. Never forget that even few loops on a cable can cause severe heating by electric induction.

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
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.
