Effective Cell Balancing in BMS: Maximizing Battery
To assemble a usable Lithium battery, individual cells are connected in series to increase the voltage. For example, a nominal LiFePO4 12V (12.8V)

One of my LiFePo4 cells'' voltage spikes above 3.37 volts is
If the connection isn''t good enough it will have a higher resistance and that will cause the BMS to see a higher voltage. You can double check things with a multimeter to see if the voltage is actually spiking

Simulation of voltage imbalance in large lithium-ion battery packs
In order to reduce load currents and consequently ohmic losses within battery packs and charging infrastructure, system voltage is usually increased by connecting cells in series.
-
One cell always higher
Due to the nature of lithium cells connecting them in parallel will not provide sufficient voltage top balancing. The current that flows between the cells at your 3.3xx volts is almost nothing.
