FEATURES
> Input voltage as low as 10 volts.
> Auto charging current adjustment for voltage peak region with auto-cutoff when battery cells are fully charged.
> Load polarity protection,short protection and input polarity protection.
> Parallel pack cell charging.

The Supermate 4 charger is designed to independently control the charging. Each individual cell of a battery pack (parallel charging) up to 4 cells. This type of charging requires that your pack have a separate parallel-charging connector. The advantage of this type of charging is that it eliminates the interference between cells of a battery pack during charging. For example, in series charging, if one of the cells in the pack is defective and is capable of taking a charge of only up to 2.8 volts or less, that extra 1.4 volts will be added to the 4.2v charge of the good cell(s). That means that if you were charging a 2-cell pack, the good cell would receive a charge of 5.6 volts or more. this, at the very least, would ruin the good cell and increase the possibility of its venting or catching fire
