ElectroMaax LiFePO4 G31 12V 128AH lithium battery with Active Cell Balancing! *** TEMPORARILY OUT OF STOCK - Please contact us for details *** By removing the internal BMS and replacing it with our proprietary Enhanced Capacity Active Balancing (ECAB) technology we have managed to increase the capacity, lifespan and performance of our already hard to beat G31 114AH LiFePO4 battery. Active Cell Balancing Active (though slightly more expensive) versus Passive has numerous advantages: • Increased Battery Life span • Increased Battery Capacity – 128AH in 100AH size • Safety - Less Battery generated heat • Safety – Improved voltage regulation • Safety – “Smart” Variable rate balancing • Reduced “Stand–by” power drain • Reduced charging time ECAB (Enhanced Capacity Active Balancing) is the next technological step for Active balancing! Here's what's new: The capacity has increased from our standard 114AH LifePO4 battery to 128AH. The ECAB keeps cells active and prolongs their longevity. Multiple batteries can now be connected in series, to create a 24V battery bank. By managing the battery externally we are able to provide higher charging rates up to 1C. *** Requires external BMS These batteries are designed, developed and manufactured in Canada and weigh in at only 34 lbs (15.4 kg) each! The battery dimensions are 11-7/8" x 6-1/2" x 10" (300 x 165 x 254mm)
