200Ah Lithium Battery - 12V, 24V, 36V and 48V Models

200Ah lithium batteries are able to store and release large amounts of energy and are often used as individual batteries or as part of larger battery packs for powering trolling motors, electric vehicles, as RV house batteries, as inverter batteries, as off-the-grid batteries, etc.

200Ah lithium batteries are deep cycle batteries based on the Lithium Iron Phosphate (LiFePO4) chemistry and can be found as 12V, 24V, 36V, and 48V batteries, but can be also custom made with even higher voltages.

 200Ah Lithium Batteries Features and Specifications

Lithium Iron Phosphate (LiFePO4) batteries feature a nominal voltage of 3.2V per cell, with the maximum, recommended charging voltage of 3.6-3.7 volts and minimum recommended discharging voltage of 2.6-2.8 volts.

So, in order to create larger battery packs, manufacturers connect several cells in series:

- 12V nominal voltage: 4 cells in series, actual voltage 12.8V,

- 24V nominal voltage: 8 cells in series, actual voltage 25.6V,

- 36V nominal voltage: 12 cells in series, actual voltage 38.4V,

- 48V nominal voltage: 16 cells in series, actual voltage 51.2V.

In order to create larger battery packs in terms of capacity, thanks to the developments in chemistry and technology in general, manufacturers use larger and larger individual customized cells.

For example, in order to create a 12V 200Ah lithium battery, manufacturers can use:

- 4 (four) 3.2V 200Ah cells connected in series (4S1P), or

- 4 (four) 3.2V 3Ah 18650 cells connected in series and then 67(!) such groups (268 individual 18650 batteries) connected in parallel to create a 12V 200Ah (actually 201Ah) battery pack (4S67P).

Note: this is just an example. But, it shows that it is much easier to design and manufacture a 4S1P lithium battery and create Battery Management System (BMS) that will control and monitor such battery.

Battery Management Systems (BMS) that come with the lithium batteries monitor the battery condition and charging/discharging currents, voltages, and temperatures and if certain thresholds are met, BMS disconnects the battery from the electric circuit in order to protect the battery.

Individual 200Ah cells are not small and 200Ah lithium batteries are not small - most 12V and 24V 200Ah lithium batteries belong to the BCI Battery 4D (6D) groups, while 36V and 48V 200Ah lithium batteries are made as custom, non-standard, battery packs.

Note: BCI Battery 4D group feature maximum dimensions of 20.75 x 8.75 x 9.875 inches (527 x 222 x 250 mm), while BCI Battery 6D group feature maximum dimensions of 20.75 x 10 x 10.25 (527 x 254 x 260 mm). Most of the 200Ah lithium batteries that are labeled as 4D batteries are somewhat wider and technically belong to the 6D group.

We have really tried to verify every single bit of information in this chart, especially allowed/supported parallel/series connections, but things may change over time...

Of course, there are other lithium 200Ah batteries, too, these are just some of the most popular ones.

Parallel/Series Connections column lists recommended parallel/series connecting options of individual batteries, as recommended by their manufacturers. Since things may change over time, before buying the batteries, please check this, but other values as well.

Note: When connecting lithium batteries in parallel and/or series, always connect them as recommended by their manufacturer - this can not be emphasized enough. Also, always use the very same models from the same manufacturer, preferably from the same batch.

If higher voltages or larger capacities are required, larger battery packs can be made using the batteries that support connecting in series and/or parallel.

However, it is also possible to order custom individual packs from certain brands, but that is another story.

200Ah Lithium Batteries as Inverter, RV House, and Trolling Motor Batteries

200Ah lithium batteries are used in many marine, automotive, industrial, and off-the-grid applications.

By analyzing how these batteries behave as inverter batteries, RV house batteries, and as trolling motor batteries, it is easy to conclude how they can be used for other purposes as well.

200Ah Lithium Batteries as Power Inverter/RV House Batteries

Power inverters are often used in off-the-grid applications, in cars, boats, and RVs to convert the energy stored in batteries into 120V AC and similar.

In order to calculate the maximum required power that the battery must provide, one must know the output power of the power inverter and its energy efficiency.

Or, by knowing how much energy can battery provide, one can calculate the maximum output power that a power inverter can provide.

Since 200Ah lithium batteries can provide at least 100 Amps continuously, when they are used to run a power inverter with an energy efficiency of at least 85%, then:

- 12V 200Ah lithium battery:

P(input) = 12.8V * 100A = 1280W

P(output) = P(input) * 0.85 = 1088W

- 24V 200Ah lithium battery:

P(input) = 25.6V * 100A = 2560W

P(output) = P(input) * 0.85 = 2176W

- 36V 200Ah lithium battery:

P(input) = 38.4V * 100A = 3840W

P(output) = P(input) * 0.85 = 3264W

- 48V 200Ah lithium battery:

P(input) = 51.2V * 100A = 5120W

P(output) = P(input) * 0.85 = 4352W

Few Notes:

- 200Ah lithium batteries can provide 100 Amps for almost two hours. This "almost" depends on the battery model and brand.

- if the energy efficiency of the power inverter is >85% output power can be even larger.

- over time, the output voltage of the lithium batteries drops down to 12V (or down to 24V, 36V, 48V) and the battery is unable to provide power as calculated without increasing the current - hence, in real life one may not expect two hours of operation. Exactly how long will 200Ah lithium battery provide 100 Amps and at what voltage is model dependent.

- power inverters usually feature surge power that is ~2x their nominal power. In this example relatively low 100 Amps is used, so almost all (almost, but not all!) 200Ah lithium batteries can provide 200 Amps for at least short periods of time.

As one can see, by increasing the voltage and keeping the current at the same level (100A in this example), cables of the same thickness can be used with the same absolute energy losses, but with smaller relatively absolute energy losses - one more reason to switch from 12V to higher voltages, depending on the application.

200Ah Lithium Batteries as Electric Trolling Motor Batteries

In order to keep the maximum current at acceptable levels (up to 50-60 Amps), electric trolling motors are offered at different voltages:

- 12V electric trolling motors are used for thrust levels up to 55-60 pounds,

- 24V electric trolling motors are used for thrust levels up to 85-90 pounds,

- 36V electric trolling motors are used for thrust levels up to 150-160 pounds,

- 48V electric trolling motors are used for thrust levels of 150 pounds or more.

For example: regardless of the voltage, if any of these motors draw 60 Amps, 200Ah lithium battery can power it for at least 3 hours - just be sure to pick the battery with the right voltage.

However, if the electric trolling motor is pushed constantly at its 100% power, that electric trolling motor is seriously underpowered, with no reserve power for emergencies, like strong currents, winds, and similar.

In real life, electric trolling motors are on average used at 50-60% of their nominal power - if the electric trolling motor draws 30 Amps, then a 200Ah lithium battery can power it for more than 6 hours, and that is a lot.


ampere time 12v 200ah plus w150pxLong Story Short: 200Ah lithium batteries are able to store plenty of energy and release it when required. With the increase of the voltage, one must be more and more careful when dealing with these units - they do feature Battery Management Systems that protect the battery from unwanted events, but better safe than sorry ...

When charging lithium batteries using mains power or power generators, always used lithium battery chargers or battery chargers with the dedicated lithium battery charging mode.

When charging lithium batteries using solar panels, always use charge controllers that are intended for lithium batteries or feature lithium battery charging mode.

And of course, be sure that the voltage is right ...
