24V Lithium Battery 100Ah Buying Guide:
A 24-volt battery is used for a wide range of purposes. Utilizing a solar
power system, a 24v lithium-ion battery is perfect for storing energy for a
residence. When electricity prices are high, having a solar power system at home
is advantageous.The 24v lithium-ion battery can be used to store energy for
electrical tools like the electric drill. Because it can store power for longer
periods of time, the battery is perfect for electrical instruments.
Additionally, lithium-ion batteries are quite lightweight, which is exactly what
you need while using electrical tools.
RV lithium batteries, or recreational vehicles, are growing in popularity in
the automotive business today. The main drawbacks of RVs have been eradicated
thanks to technological improvements. Owning an RV used to be expensive because
it required fuel to operate (oil). Fuel is not environmentally friendly because
it costs a lot and cannot be recycled. Its price also changes drastically and
abruptly. The RV solar system can also power all the devices you need to use in
your RV, just as a household solar system can. By using the sun during the day,
you can charge the lithium RV battery for free and enjoy its stored energy at
night.
Buy the right size battery
Purchasing the proper sized battery for your application can be intimidating.
Too small, and you find yourself running out of juice too soon. Too big, and you
may be spending extra money when you didn’t have to. To understand calculating
our perfect battery size, we must first learn a few basic definitions.
VOLT OR VOLTAGE (V):
Voltage is the pressure from a power source that is pushing electrons through
a loop, enabling them to do work such as power a trolling motor or turn on a
light bulb. Batteries are marked with a nominal voltage that is fixed (such as
12, 24, 36, or 48 volts). On the other hand, electronic devices will always
operate when receiving a fixed voltage. For example, a 12-volt device needs a
battery that supplies 12 volts to operate.
CURRENT – AMPERE (A):
If voltage is the pressure, current is the flow rate. An ampere, or amp, is
the international unit used for measuring current. Amp's measure how much
electricity “flows” per second. As the rate of current goes up, the measure of
amps will also go up. An electronic device usually works on a fixed voltage, but
the number of amps it draws can vary. One example is a dimmer light switch, as
you slowly raise the dimmer switch you are slowly increasing the amps being sent
to the light bulb. The voltage does not change, but the increase in amps will
increase the brightness of the light bulb. The same holds true with operating a
trolling motor.
Example: I have a 55 lb trolling motor running on speed setting 4. The
trolling engine runs on 12V and draws 15A at that speed. If I increase to speed
setting 8. The motor still runs on 12V but now pulls 30A. The voltage remains
the same but the number of amps increased.
POWER – WATTS (W):
Power is volts multiplied by amps, or W = V x A. Power is generally measured
in watts (W). This is the amount of energy consumed by a device and therefore an
indication of how powerful it is.
Example: I have a 12V trolling motor that draws 30 amps. The power
consumption is 12 x 30 = 360W.
It is important to note that power can change on the same device if the amps
are increased.
Example: I have a 24V trolling motor that I am running on speed setting 3.
The motor runs on 24V and draws 10A. This would give it a power consumption of
240W (24 x 10 = 240). If I increase my speed setting to 5, the motor now draws
15A, but still runs on 24V. The power consumption of the trolling motor is now
360W (24 x 15 = 360).
CAPACITY – AMP HOURS (AH):
Amp hours, or Ah, is a measurement of battery capacity. The Ah rating of a
battery tells us how many amps the battery can deliver in one hour. Higher Ah
rating means more runtime. As an example, a 12V lithium battery with a capacity
of 100Ah can deliver 100Ah to a 12-volt device for one hour. This also means
that the same 100Ah battery could operate a 12V device for 4 hours if the amp
draw was 25 amps (100 ÷ 25 = 4). When measuring capacity, we see two values:
rated capacity and usable capacity. When shopping for batteries, it is important
to understand lithium batteries have a significantly higher proportion of usable
capacity than lead acid batteries. For more information about the differences
between these two battery types, check out this article.
Example: I run my 55 lb trolling motor at speed setting 4, drawing 15A at
12V. I have a 12-volt battery of 100 Ah. My total run time is now 6.7 hours (100
÷ 15 = 6.7). When I switch to speed setting 8 the motor draws 30A. My total
runtime is now 3.3 hours (100 ÷ 30 = 3.3).
CAPACITY – WATT-HOUR (WH):
Another commonly used terms to measure battery capacity is Watt-hour, or Wh.
Wh is calculated by multiplying battery voltage and amp hours. For example, a
12v 54Ah battery would have 648Wh (12 × 54 = 648). A 36v 100Ah battery has
3600Wh (36 × 100 = 3600).
