To power a 50W speaker, a large capacity battery and stable output voltage should be used to provide sufficient power. Here are some suggested battery models:
1. Lithium batteries: such as 18650, 26650 and other models, with large capacity and stable output voltage, suitable for high power consumption equipment, but you need to pay attention to safety issues when using and loading.
2. Nickel-metal hydride batteries: such as AA, AAA and other models, which have no memory effect and are easy to obtain, but have a small capacity and require the use of multiple batteries in series.
3. Lithium titanate battery: Compared with lithium batteries, lithium titanate batteries have more stable performance and are safer, but the price is relatively high.
4. Lithium iron phosphate battery: comparedCompared to other batteries, lithium iron phosphate battery has higher safety and stability, longer life, but smaller capacity and requires the use of multiple batteries in series.
You should choose a suitable battery model according to the actual situation and pay attention to battery usage and charging safety issues.
