Product Parameters Can be connected in series(up to 4) and in parallel Battery voltage after full charge: 13.4V-13.8V Total Capacity: 100Ah Nominal Voltage: 12.8V Max. Continuous Current: 100A Max. Continuous Load Power: 1280W Max. inverter Recommend: 2000W Charging Current Recommend: 20A-40A Waterproof Rate: IP65 Operating temperature range Charging: 32℉--113℉ Discharging: -4℉--140℉ Storage temperature: 14℉-122℉ Product size: ( L * W * H ) 12.9 5* 6.77* 8.42 inches Note: The charging voltage shall meet 14.2v-14.6v, and battery voltage will drop after being fully charged, which is a normal phenomenon of LiFePO4 battery. After standing for one day and one night, the voltage of the battery will stabilize between 13.4v-13.8v (100% capacity). If you need to use the battery in series, follow the steps below. Step 1. Fully charge each battery separately. Step 2. Connect the fully charged batteries in parallel and place them for more than 2 hours. Step 3. Disconnect all batteries and measure the voltage of each battery separately. If they are equal, connect them in series. Otherwise, repeat steps 1 and 2. The above steps can improve the discharge performance and service life of the battery after series connection. Parallel connection can be directly connected without any operation.
