Charger
The DNA 200 has a built in 1A USB charger. It automatically detects the type of USB power supply it is
connected to, so it can be plugged into standard PC USB ports or higher power chargers. The max charge
current is based on the cell capacity as programmed in EScibe.
Cell-by-cell monitoring
The DNA 200 runs from a three cell battery. Because lithium polymer cells can be damaged by excessive
discharge, with multi-cell series batteries it is important to measure each cell in the battery
independently and stop firing the atomizer when any of the cells reaches the cutoff voltage. The DNA
200 uses the battery pack taps to monitor each cell.
Cell Balancer
During charging, is vital that none of the batteries charge beyond 4.2 volts per cell. If one of the cells in
the battery has more charge than the others, its voltage will be higher. During charging, the DNA 200
will turn on a “balancer” to charge that cell slower than the others.
By monitoring and charging each cell individually, the safety of a multi-cell pack is equivalent to using a
single cell. Many products, from power tools to laptops to electric vehicles, use multi-cell packs. All of
them use cell by cell monitoring and balancing to operate safely.
