This manual contains variuos sections: Section 2 is for LOW VOLTAGE APPLICATION Section 3 is for HIGH VOLTAGE APPLICATION In case of product upgrades or other reasons, this document will be adjusted accordingly.

  • Page 7: Preface

    You can request technical support from service@wecobatteries.com. WeCo offer two types of warranty on its products, the Manufacturing defects also called functional warranty and the performance warranty. More information can be found in this manual and on the specific warranty document available for each battery model.

  • Page 8: System Design

    Operating Temperature and Thresholds Many chemical reactions are affected by temperature and this is also true for the reaction that occurs in a WeCo storage battery. The chemical reaction of a lithium ion is slowed down by the lowering of the temperature of the electrolyte contained in the battery, which results in a lower capacity and a higher rate of long-term performance decay in direct proportion to the departure from the optimal temperature prescribed by WeCo.

  • Page 9: Charging

    All WeCo batteries produced from the beginning of 2019 can be equipped with a WiFi system for connection on WeCo Cloud, this solution ensures that they are always updated to the latest FW version notified in the APP, the Upgrade function must still be driven by the user as during the update the battery must be turned off for safety reasons and it is therefore necessary to plan this action in such a way that no inconvenience is created for users of the system.

  • Page 10: Warranty

    WeCo APP. From time to time, WeCo will release a new firmware to improve the functionality of the battery, if your battery will be equipped with WiFi (Paid accessory) and you will be registered on our APP, the new firmware will be visible in the APP and updatable with a simple click from your phone.
