Featured How Much AH for ~ 250 Amps

Blackout67 said:

Have a JP13 (~220 amps, 2050 watts @ 1 ohm) and Recoil 80.4 (~20-30 amps @ 4 ohms) and tryna pick out a supporting battery. Going stock alt and starting batt with big 3 and looking to put an AGM in the trunk.
Screenshot are some decent priced ones with good reviews and decent warranties. Also was considering Everstart AGMs from Walmart

Just want enough to support my amp draw, dont plan on going full tilt constantly just want steady voltage, and will get the better one if the advances are worth it but I'd prefer to stay cheaper and lighter in weight
No I do not want to pay or deal with setting up a lithium battery.

Thanks in advance

When selecting a supporting battery for your audio setup, you want to ensure that the battery's capacity and discharge rates can accommodate your amp's draw. Here’s a quick comparison of the options you shared:

1. Mighty Max Battery (50 Ah, 570 CCA):
- Pros: Affordable, compact size, decent reviews, maintenance-free.
- Cons: May not provide enough sustained power for peak demands, limited capacity.

2. Weize Battery (55 Ah, 650 CCA):
- Pros: Higher cold cranking amps, good reviews, slightly larger capacity.
- Cons: Still may be on the lower side for power needs if used frequently at high output.

3. Renogy Battery (100 Ah, 1100 A max discharge):
- Pros: Significantly higher capacity, better suited for extensive use, can handle high discharge rates.
- Cons: More expensive and heavier—may not fit your preference for lighter weight or budget.

### Recommendations:

• For your needs, if you primarily want steady voltage without going full tilt constantly, the Weize Battery would likely offer a good balance between price and performance.
• Consider the Renogy Battery if you think you might use your system at higher outputs more often, as it offers substantial capacity.
• Avoid the Mighty Max Battery if you anticipate frequent high demand, as it may not keep up.

### Additional Tips:

• Ensure your alternator and main battery setup can adequately support your system.
• The Big 3 upgrade will significantly enhance voltage delivery to your audio equipment.

These choices will help support your amp's demands. Consider how you plan to use the system to determine the best balance of cost and performance.
