Description
The Pro-Aqua 300 microprocessor-controlled IP-65 lithium battery charger was specifically developed for harsh conditions where water may be present. With the automatic 4-step charging program the battery pack will be charged safely. The output of the charger is electronically protected against short circuit and reverse polarity connection. The charger is able to recover over discharged batteries. Four LED’s on the top case are used to indicate charging status and errors.
