AP681BLC Charger
User Manual 1.0 ref. : 7709
We thank you for buying the Pro-Tronik AP681BLC charger. This high quality product features a high performances microprocessor and a
specialized software dedicated to the charge, discharge and cycling of RC models batteries.
We recommend you to read the entire manual before using the charger. If you have any doubt regarding the product usage, please ask assistance
from an experienced modeler, a specialist, or simply contact our on-line technical support team on www.a2pro.fr .
Overview
• The Pro-Tronik charger features many automatic functions which adjust the charging current and voltage during charge / discharge process.
Regarding the Lithium batteries, a special process is used, reducing significantly the over-charge and fire risks, generally due to user
programming errors. The charger is designed to stop any erratic charge process, when this arises.
• The Pro-Tronik charger uses a sophisticated balancing circuit allowing the charger to check and balance each lithium cell in real time (when
balancing socket is used in).
• The charger program is able to fast charge the Lithium batteries, reducing the charge time compared to standard charging process (please
always respect the cells manufacturer recommendations). The charger is also able to charge / discharge Lithium cells in order to store them for
several weeks without damaging the cells. A long storing time can deteriorate the battery chemistry and performances when they are not stored
at an appropriate voltage.
• The end charge function is based on the delta Peak sensing method. When the cell voltage reaches a programmed value, the charge process is
automatically ended (for some batteries special values need to be manually entered, please check further sections of manual for details)
• It is possible to let the charger decide of the maximum charge current or to input the value manually when charging Ni-Cd / Ni-Mh batteries.
This can be helpful when charging cells with low internal resistance.
• The maximum capacity is always calculated on the charge time multiplicated on the charge current. If a maximum (limit) value is set up, the
charging process will stop once this value will be reached. Use this function only if you are sure about the value you enter.
