The Rhythm P2 Battery System: No Extended Battery, Just Add More

The Rhythm P2 operates on a single 14.4V lithium-ion battery, which provides varying runtime depending on the oxygen flow setting. Unfortunately, if you need more power, you cannot buy an extended battery, instead, you simply purchase additional P2 batteries and swap them out as needed. This approach ensures you always have a backup ready.

The Importance of an External Charger

Since the Rhythm P2 can only hold one battery at a time, an external battery charger is a must-have accessory. This allows you to:

• Charge spare batteries while using the machine—no downtime.
• Maintain continuous oxygen flow by rotating charged batteries.
• Stay mobile without worrying about finding an outlet mid-use.

The external charger connects to a standard wall outlet or car adapter, making it ideal for travel.

2. Invest in an external charger to keep spares ready.
3. Understand that single/double/triple batteries are for the P2-S4 only.

By planning ahead with extra batteries and a charger, you can maintain your active lifestyle without worrying about power limitations.
