Product description Benefits of using 12.8V 100Ah batteries in combination: Multiple 12.8V 100Ah batteries can be combined in series or parallel. When connected in series (+ to -, + to -) the voltage rises; when connected in parallel (+ to +, - to -) the current rises, thus increasing the total power. 1. Increased capacity: Combining batteries in parallel increases the overall capacity, allowing for longer runtime. This can be beneficial in applications requiring extended power supply, such as solar systems or electric vehicles. 2. Increased voltage: Combining batteries in series increases the overall voltage, which can be advantageous in applications that require higher voltages, such as inverters or electric power tools. 3. Redundancy and reliability: Having multiple batteries working together provides redundancy. If one battery fails, the others can continue to provide power. This improves the overall reliability of the system. 4. Flexibility: Using batteries in combination allows for flexibility in meeting different power requirements. You can adjust the configuration based on the specific needs of your application. P.S. Accessories used in combination need to be purchased separately NOTE: Before using in series or parallel, must be make sure that each battery is 100% fully charged. Otherwise, the individual voltages will be unstable and will need to be fully charged individually before responding again. FAQ Q1. Can not discharge？ Confirm the battery is firmly connected.Confirm the positive and negative terminals of the battery are connected correctly.Confirm the battery voltage is more than 12V, if it is less than 12V, please charge the battery first.Confirm the load voltage matches the battery.Confirm whether the load current is more than 100A, make sure it is less than 100A.Make sure the discharge temperature is -4℉~+140℉. Q2: Can not charge? Check that the battery is securely connected. Confirm whether the positive and negative terminals of the battery are correctly connected.Confirm whether the charging voltage matches with the battery and whether the charging parameters are set correctly. P.S. Must Use Charger adapter with a voltage of 14.6V±0.2V. A 12V charger will not fully charge this battery.Confirm the charging current is greater than 100A, make sure it is less than 100A.Confirm the battery voltage is lower than 9V, if it is lower than 9V, please use a charger with 0V charging function to charge. make sure the charging ambient temperature is 0.5V and the charging temperature is 0.5V.Make sure the charging ambient temperature is 32℉ ~ +131℉. After the battery over-discharge protection, disconnect the load and wait until the battery voltage is restored before charging, or use a charger with 0V charging function to charge.

Características

• Shipping Information: Due to weight, our batteries come one battery per box. For orders of two batteries that are placed on different trucks, the shipments will result in not being delivered at the same time. Please be patient
• Compact & High Energy: GRNOE 12V 100Ah battery measures 12.9*6.7*8.6 inches and weighs 22.48 pounds, which is only 33% of traditional lead-acid batteries, and has an energy density of 57 Wh/Lbs, making it a suitable replacement for SLA/AGM batteries. Our battery life is more than 10 years than traditional batteries, saving you more money
• Smart Low-Temperature Cut-off: The 12V battery has a low-temperature protection function. The discharge temperature can be as low as -4. When it is below 32, BMS will cut off the charging immediately. Widely used in RVs, cabins, or off-grid in cold winter. Advanced BMS protection system protecting the battery from overheating, overcurrent, overcharge, over-discharge and short circuit. P.S. Use an adapter with a voltage of 14.6V0.2V. A 12V charger will not fully charge this battery
• Reliable & Safe Battery: GRNOE 12V lithium battery adopts advanced A+ grade LifePO4 cells and is UL/UN38.3 certified, with higher energy density and more stable performance. The internal structure is optimized and new structural components are used to make the battery more compact, improve the high performance of the battery and ensure safety
• Wide Application: The GRNOE 12V 100Ah LiFePO4 battery delivers rapid and reliable power, supporting a max discharge current of 300A for 3 seconds and IP65 waterproof which is very suitable for 12V 36-55lbs trolling motor and can also be used in off-grid systems, RVs battery, home backup, Automotive Replacement Batteries and other fields. P.S. The battery is suitable for Trolling Motors, Marine, Boat rather than Start-Up
• Lifetime Support: Within 36 months from the date of order, excluding human-caused failure events, we will promptly replace the product after confirmation. Welcome reach out to us with any questions, we are always here for you
• Usage Guidelines: The GRNOE LiFePO4 battery is intended for use as an energy storage purpose. Please do not use this battery as starting batteries, golf cart batteries, or jacks. After first receiving the battery or switching it off, you need to charge the battery using a 14.6V lithium-activation charger to activate the battery. Do not use 12V, lead-acid, or automotive chargers, or chargers with a repair/desulfation mode, as they may interfere with the Battery Management System (BMS) and trigger premature protective shutdown, or even damage the battery
• Battery Maintenance: Before connecting batteries in series, please ensure they are fully charged and that the voltage difference does not exceed 0.2V (the battery is considered fully charged when it reaches 14V or higher). To maintain battery health and prevent damage due to inactivity, it is recommended to charge the battery at least once every two or three months
