The ACOPower 12V 200Ah LiFePO4 Deep Cycle Lithium Battery is a 12.8 volt lithium iron phosphate battery with 2,560 watt hours of energy and a built-in 200 amp battery management system. It can deliver up to 200 amps continuously, enough to run a 2,000 watt class inverter, and ACOPower rates it for more than 4,000 charge cycles.
LiFePO4 chemistry is one of the safest and longest-lasting lithium types for deep cycle use. Compared with lead-acid, it is much lighter for the same capacity, holds a steady voltage as it discharges, and can use nearly all of its rated capacity without being damaged. That makes it a strong upgrade for RV house banks, off-grid solar storage, boats and backup power.
At 12.8V and 200Ah, one battery stores 2,560Wh. That is roughly the usable capacity of four 100Ah lead-acid batteries discharged to 50%.
The built-in BMS protects against over-charge, over-discharge, over-current, short circuit and out-of-range temperatures. It supports 200A of continuous discharge for a maximum output of about 2,560W.
ACOPower rates the battery for at least 4,000 cycles, many times the cycle life of typical lead-acid deep cycle batteries.
Connect up to four batteries in series for a 48V system, or connect multiple batteries in parallel for more capacity at 12V.
The battery charges from 0°C to 50°C (32°F to 122°F) and discharges from -20°C to 60°C (-4°F to 140°F). Store it between -10°C and 50°C.
RVs and campers. Replace heavy lead-acid house batteries with more usable capacity at a fraction of the weight.
Off-grid solar. Store daytime solar for evening and overnight use in cabins and tiny homes.
Boats. Power electronics, fish finders, trolling motors and house loads.
Home backup. Pair with an inverter to keep essentials running during outages.
Versus lead-acid and GEL batteries. Lead-acid batteries cost less up front but weigh much more, offer only about half their capacity for regular use, and wear out sooner. LiFePO4 usually costs less over its lifetime.
Versus two 100Ah lithium batteries. One 200Ah battery means fewer connections and a single BMS. Two smaller batteries are easier to lift and fit into tight spaces.
Versus other lithium chemistries. LiFePO4 is more thermally stable than NMC lithium, which is why it is preferred for RVs, boats and home storage.
This may be a good fit if
Use a charger or controller with a LiFePO4 or lithium setting that charges to about 14.4V. Lead-acid settings with equalization should not be used.
No. Charge it between 0°C and 50°C (32°F and 122°F). It can discharge down to -20°C (-4°F).
Up to four in series for a 48V system, or several in parallel for more capacity. Use batteries of the same model and similar charge level.
Divide 2,560Wh by your load in watts. A 200W load runs for roughly 12 hours, allowing for inverter losses.
The ACOPower 12V 200Ah LiFePO4 Deep Cycle Lithium Battery combines high capacity, a 200A BMS and thousands of cycles in one 12V battery. At Outbound Power, we help customers size battery banks and match chargers and inverters. If you have questions, our team is happy to help.
