Modular batteries are advanced energy solutions that can be connected in parallel or series to increase capacity or voltage. They are widely used for devices that require high capacity or high voltage in order to operate.
Grepow’s modular batteries are LiFePO4 (Lithium Iron Phosphate), and they carry a BMS in order to provide a long lifespan and high level of safety. They are a great drop-in replacement for lead-acid batteries.

Where one power module fails, another takes over. You can replace single faulty units while the rest of the system continues to function flawlessly, increasing the reliability of the system.
Compared to a regular packed battery, a modular battery can extend your system as you want. You can add additional units as your power and business needs change and grow. The battery has an internal BMS that can be supported in multi-series and/or -parallel (up to 4S10P), which allows your capacity and voltage to be easily expandable.
The pack consists of environmentally friendly and safe LiFePO4 cells with long cycle life and deep-cycle discharge. It does not require frequent replacing. The battery is sealed with ABS plastic that has an IP66 rating. It allows the battery to be waterproof and shockproof.
Grepow Modular batteries are advanced energy solutions, widely used to requiring high capacity or high voltage devices. Such as solar and wind energy storage, portable medicial equipment, marine, RV, off-grid or micro-grid systems, communication power system, UPS systems, security system and emergency lighting power.
A: Yes, 327x172x217 mm is the size of 12V 7Ah lead-acid replacement. If you have additional requirements on the size, we can customize it for you.
A: Lithium iron phosphate battery (LiFePO4) has the advantages of large capacity, lightweight, environmental friendly, safety, and more cycles. This is an alternative to lead-acid batteries, and it is safer than LiPo batteries.
