Interface Introduction

Note: all interfaces can be charged and discharged! ① Charger interface (3-pin airhead，GX20) It can also be used for small current discharge （less than 20A）. ②③ 8mm terminal output interface (red is +, black is -) The current is not more than 100A, and the power is not more than 1200W, please connect this terminal. Suitable for connection with 8 mm diameter copper nose. It can also be used for charging. ④⑤ Square terminal output interface (red is +, black is -) If the current exceeds 100A or the connected load exceeds 1200W, please connect this terminal. Suitable for connection with 6 mm diameter copper nose. It can also be used for charging. ⑥ Battery power and voltage display Note: the data displayed during charging and discharging is not accurate. Please use it when the battery is still.
