TIPS
Please use a lithium charger to charge the batteries, other types of chargers may cause damage to the batteries due to different charging stages and modes. If you have related problems, please feel free to contact us.
Storage:
1. Keep your battery in a cool and dry place (preferably between 32°Fand 108°F). charginging temperature: Charge at 32°F-108°F;Discharge at -4°F-131°F.
2. Never store your battery fully discharged, it's best to put a 50% charge on your battery and avoid leaving for a long period of time without charging. Recharge the at least every 3 months. Do not immerse in water.
3. Cleaning: Never use a steam pressure washer when cleaning the battery .Never completely immerse the battery in water. Wiping it off with a damp cloth.
Note for the batteries, when Connecting the batteries In Series or/and In Parallel
1.From same brand and purchased recently time,And same battery capacity(300Ah)
2.Fully charge the battery separately(voltage at rest>13.4V)
3.Connect the batteries one by one in parallel and leave them together for 12-24hrs
