【Long Lasting & Charging More Than 4X Faster】Our 12.8V 100Ah lithium battery has 1280Wh energy (12.8V×100Ah×100%DOD=1280Wh), which is close to the real energy of 12V 200Ah lead-acid battery (12V×200Ah×60%DOD=1440Wh), as the depth of discharge (DOD) of lead-acid is about 60%. It means a 12V 200Ah lead-acid can run an 100W TV nonstop for 14.4hrs while 12.8hrs as our 12.8V 100Ah battery can. And it takes 10-20hrs to fully charge a 200Ah lead-acid battery while 1-5hrs of our battery. How efficient!
【1/5*Lightweight & More Flexible Applications】Rock Power Master 12.8V 100Ah LiFePO4 battery has a lightweight of 25.55lbs, only 1/5 of a 12V 200Ah lead acid battery (about 130lbs). Meanwhile, our batteries support Max 4S or 4P connections to get more capacity (200Ah, 300Ah, Max.400Ah) and higher voltage (25.6V, 38.4V, Max.51.2V). No more worries about overweight and limited capacity, it’s perfect for trolling motor, camping, RV, solar & off-grid, and makes your trip as easy as plugging in at home.
【Top Protection & 8X Lifetime】Rock Power Master battery is made of automotive grade LiFePO4 cells and built-in 100A BMS to prevent overcharge, over-discharge, over-current, overheating & short circuit. Compared with the 200-500 cycles and 3-year lifespan of lead-acid, our battery has more than 4000 deep cycles and a 10-year lifespan, which means that the lifetime of one of our 12.8V 100Ah LiFePO4 battery is equivalent to the total lifetime of 3-8pcs 12V 200Ah lead-acid batteries. What a huge difference!
【Automotive Grade Lithium Battery】Rock Power Master adopt Automotive Grade LiFePO4 Cells with higher energy density, more stable performance & greater power, and insist on providing customer with environmentally friendly green power solution. All Rock Power Master battery meets UL Testing, CE, FCC, ROHS, PSE, IP65 certifications. Highest grade of battery cell and authoritative accreditation enable Rock Power Master battery growing as LiFePO4 battery leader.
【BMS Protection & IP65 Waterproof】Rock Power Master LiFePO4 battery has built-in 100A BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, and short circuit with excellent self-discharge rate. Built-in high-temp cut off prevents charging over 167 °F (75 °C). Without memory effect, no matter what state the battery is, it can be used as soon as it is charged. Rock Power Master LiFePO4 battery is IP65 level waterproof, which set you free from worrying to install indoors or outdoors.
【Deep Cycle Lithium Batteries】Rock Power Master Lithium Iron Phosphate Battery can be recycled up to 4000~15000 times and provide up to 10 years of service life, which is more than 8 times comparing with Lead-acid batteries. Due to its safety and stability, LiFePO4 battery can perfectly replace the traditional lead acid battery.
【Capacity Expansion & Widely Used】Rock Power Master 12.8V 200Ah Lifepo4 Batteries support connecting up to 4 identical batteries for up to: 48V (51.2V) 200Ah battery system (when in series)、 12V (12.8V) 800Ah battery system (when in paralel). Powerful energy expansion system could be widely used for home storage system (avoiding the effects of power outages), off-grid system, RV, trailer, and outdoor activities. Much more flexible to DIY your own battery system accordingly.
【Automotive Grade Battery Cells & Upgrade 200A BMS】Rock Power Master 12V 200Ah Plus LiFePO4 batteries have exceptional quality since they are manufactured by 8 Automotive Grade LiFePO4 Cells with higher energy density, more stable performance & greater power. With the built-in 200A BMS to protect it from overcharge, over-discharge, over-current, over-voltage, overload and short circuit with excellent self-discharge rate. Highest-level safety, nontoxic, renewable energy, eco-friendly for environment.
【Highest Energy Density】Rock Power Master 12V 200Ah Plus is not only 3 times the energy density of lead-acid battery, but much lighter and more powerful than comparable LiFePO4 battery on the market. For example, the energy density of Rock Power Master 12.8V 200Ah Plus is 51.61Wh/lb (2560Wh/49.6lb=51.61Wh/lb), While comparable LiFePO4 battery is 46.55Wh/lb (2560Wh/55lb=46.55Wh/lb), Which means the energy density of our LiFePO4 battery is 11% higher than the energy density of comparable LiFePO4 battery.
【Max. 40.96kWh Energy Expansion】Rock Power Master 12V 200Ah Plus batteries support up to 4 in parallel and 4 in series (Max 4P4S) to get more capacity (400Ah, 600Ah, 800Ah) and higher voltage (24V, 36V, Max.48V). Max connected in 16 batteries to build a 48V 800Ah battery system, with 40.96kWh energy, max. 40.96kW load power. This powerful energy expansion system could be widely used for our home storage system (Avoiding the effects of power outages), solar power system, RV, and outdoor activities.
【95% Efficiency & Long Service Life】Rock Power Master LiFePO4 battery’s flat discharge curve holds above 12V for up to 95%* of its capacity usage. Low self-discharge rate and low-capacity loss. Providing sufficient energy for multi-application. Our Rechargeable 12.8V 200Ah Plus lithium battery provides 4000+ cycles (10 times longer) & a 10-year lifetime compared to 200-500 cycles & a 3-year lifetime in lead-acid battery, and provides 2500 cycles longer than other LiFePO4 batteries on the market.
