Battery Packs for Breast Pump Makers
A breast pump battery must run a small motor quietly, stay cool against the body and charge safely at home. Jetray builds custom rechargeable lithium packs for portable and wearable breast pumps, for device makers.
What the pack must do
- 01Run the motor. The pump motor draws steady current, with peaks at start.
- 02Stay slim. Wearable pumps sit inside a bra, so shape and weight matter.
- 03Stay cool. The pack sits near the body, so heat control matters.
- 04Charge safely at home. Protection against overcharge, over-discharge, over-current and short circuit, plus a temperature check. BMS design
- 05Show charge level. An LED or a data link to the device. CAN, UART, RS485 and Bluetooth can be set up to your requirement.
Wearable or portable
Tell us the motor's voltage and current, and how many sessions you want per charge. We select the cells and layout. Cell options include Panasonic, Samsung, LG, Molicel and EVE. Cell selection
Wearable (in-bra)
- Common setup
- Slim LiPo or small Li-ion pack
- Points to check
- Thin, light, heat, splash protection
Portable (hand-held)
- Common setup
- Li-ion pack, two cells or more
- Points to check
- Run time per charge, charge port
Hospital-grade
- Common setup
- Larger pack or mains plus backup
- Points to check
- Long run time, rugged case
Case, splash and cleaning
Pumps meet milk and water. The pack sits sealed in the device, so the case and seals matter. IP65 is our usual level, and other levels can be made on request. Tell us how the device is cleaned and where the pack sits. Enclosure design
Order and documents
UN38.3, IEC 62133 and MSDS documents are available, with transport and certification reports for the shipment. Other standards depend on your device and market. Custom battery pack samples are charged, and you test them on your pump. Custom packs usually take one to two months. MOQ depends on the product. Cost and MOQ Quality and certification

Mistakes to avoid with breast pump batteries
- 01
Sizing for one session
WhyThink in sessions per charge and per day, including standby.
- 02
Overlooking motor current
WhyThe motor draws more at the start and at high suction. Measure it.
- 03
Heat near the body
WhyWearable pumps sit close to the user. Keep heat low through cell choice and layout.
- 04
Splash and cleaning
WhyThe pack and charging port must suit how the pump is used and cleaned.
- 05
Choosing cell size late
WhyWearable housings are small. Settle the battery space early.
