The primary difference between LiPo charge mode and LiPo balance mode lies in how the charger manages the voltage across the individual cells in the battery pack during charging.
In LiPo charge mode, the charger charges the entire battery pack to the target voltage (usually 4.2V per cell) without paying close attention to how balanced the individual cells are. It monitors the total pack voltage and stops when the overall voltage reaches the appropriate level. This mode is faster than balance mode but does not ensure that each cell ends up at the exact same voltage, which over time can lead to imbalances between cells.
In LiPo balance mode, the charger charges each cell in the pack individually and equally, using the balance lead to monitor the voltage of each cell. If one cell reaches 4.2V before the others, the charger will slow down or pause charging that cell while continuing to charge the others, ensuring all cells reach the exact same voltage. This mode is slightly slower but much safer and healthier for the battery, especially over the long term, as imbalanced cells can degrade performance or even become dangerous.
