I have a 8000 rms and a 300rms amps with a 400a alternator does anyone have any suggestions on what kind and size lithium battery I would need to run my music in my car so I have no issues with voltage drop

To determine the right size and type of lithium battery for your setup, consider the following factors:

1. Total Power Demand: Your setup has an 8000W RMS amplifier and a 300W RMS amplifier, which means:
- Total RMS Power: 8000W + 300W = 8300W

2. Current Calculation:
- The current draw (in amps) can be calculated using the formula:
\[
\text{Current (A)} = \frac{\text{Power (W)}}{\text{Voltage (V)}}
\]
- Using a 12V system (which is typical for car audio):
\[
\text{Current} = \frac{8300W}{12V} \approx 691.67A
\]

3. Battery Size:
- Lithium batteries are rated in amp-hours (Ah). To maintain performance without significant voltage drop, you'll need a battery that can handle the high draw.
- A common recommendation is to have at least 1.5 to 2 times the total current draw in Ah.
- For example, if you use a 691.67A draw, a battery bank of about 1050Ah to 1380Ah would be beneficial.

4. Alternator Consideration:
- Since you have a 400A alternator, you'll be limited to how much can be replenished while the car is running. It would be best to have a larger battery bank to run your system when the vehicle is off or during peak power demands.

5. Suggested Battery:
- Look for lithium batteries with a high discharge rating (C-rate) to ensure they can handle the current without voltage drop. Brands like Battle Born, Renogy, or Kinetik offer options that may fit your needs.

### Recommendations:

• Aim for a lithium battery setup of around 1000Ah to 1500Ah, considering your power demands and alternator output.
• Ensure proper wiring and connections to handle high currents, and consider multiple smaller batteries in parallel if necessary.

Always ensure proper installation and safety measures are taken to prevent any electrical issues.

Glowevoltage series 3.

Glowe Voltage – Series 3

Meet the new kid on the block. Clocking in at a blistering 720 amps of sustained output the Series 3 delivers more power on demand than any other battery in our lineup - and does it while being small enough to fit under your seat.

Holy crap that battery is tiny!

They pack a punch way above their weight!

You are not kidding. That price as well is great if it does what their tests claim. All that power and durability in that size, non-gassing, and built in BMS! Just seems like a plug&play pipe dream.

Yeah, the series breaks down as the series 1, higher AH, and lower constant/burst amperage, but still exceptional electrical support, the series 2, somewhere in between storage (AH) and constant/burst current, and the series 3, loads and loads of instant power, depending on one's system needs, there's one for most applications.

When I originally got this and tested it out. I did a battery delete, and the series 1 ran the whole car and the system (at the time, an even higher wattage setup, around 4.5k) for 6 weeks, without a hitch.
