FMA’s Cellpro Node Connector is a key part of the system. It enables the charger to monitor individual cells and independently charge each cell to its optimum level.
The Cellpro 10s charger may be used to charge any brand of Lithium pack using either the Cellpro adapters or pigtails. The charger includes two 5s output connectors and includes two simple 5s-to-4s adapters. This enables automatic support for any current Cellpro 2s-4s battery sold in the past. These extra accessories also enable you to connect any of the existing Cellpro 4s adapters for other brand batteries with the Cellpro 10s charger.
Using the Cellpro 10s Charge Control Software, the charger can be set to work with virtually any good, regulated power supply, even if the power supply is not designed for high power. By entering current capability; e.g., 1-25A, the charger will automatically adjust the maximum charge current to protect the programmed power supply. There is also a simple procedure that can be performed at the field to reset the input power supply to the factory default (25A) if a PC is not available. You might need to do this, if for example, you use a small AC power supply at home, but you want full charge current from your car battery at the field. This powerful feature allows you to decide how much money to spend on your power supply.

In addition to the unique features listed above, the new Cellpro 10S charger has all the features found in the FMA Cellpro 4S charger:
Faster Auto Charge rates (1.0C, 2.0C, and 3.0C), permit safe charging Lipo batteries at up to a 3C charge rate. This is only possible with FMA Direct cell-balancing technology which incorporates integrated, highly-accurate cell monitoring and balancing during charge.
