SonoScape E2 Ultrasound Compatible Battery 14.4V 6200mAh

Up to 19% off
New arrival
From $708.99 USD $872.99
Shipping calculated at checkout.
Fits SonoScape E2, E3, E1 Exp, X1 ultrasound systems; replaces OEM part number KL4S2P31B.
14.4V 6200mAh lithium-ion delivers 89.28Wh for continuous diagnostic scanning without mid-procedure power loss.
Connector seats into the rear battery slot with positive contact alignment; locking tab engages flush against housing.
We bench tested this cell on a full charge cycle; the BMS accepted the new chemistry without self-test errors.
Allow the device to complete its power-on self-test sequence uninterrupted after installation — medical ultrasound systems run BMS verification at startup, and stopping this process triggers a false battery fault that persists until full reboot.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

SonoScape E2 / E3 / E1 Exp / X1 Series — 14.4V Li-ion Replacement Battery (KL4S2P31B)

This is a 14.4V 6200mAh Li-ion replacement battery for the SonoScape E2, E3, E1 Exp, and X1 portable ultrasound systems. It carries OEM part number KL4S2P31B and slots into the same battery bay as the factory-fitted cell. Total energy is 89.28Wh.

  • E2 / E3 / E1 Exp / X1 platform compatibility: These models share a common 14.4V power rail, identical battery bay dimensions, and the same BMS handshake protocol — one cell format covers the full range without modification.
  • Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on a SonoScape-compatible test rig. The BMS negotiated charge termination correctly, and protection circuits tripped at the expected over-discharge threshold without nuisance cutoffs under imaging load.
  • Post-installation self-test protocol: After fitting, allow the device to complete its power-on self-test cycle without interruption. The SonoScape BMS runs a battery verification routine at startup — cutting power during this sequence flags a false battery fault that persists until the next full reboot.

SonoScape E2 not completing boot sequence after battery swap

The E2 runs a multi-stage power-on self-test that includes a BMS handshake before it releases the display and imaging modules. A new cell that has partially self-discharged in storage may sit just above the BMS recovery floor — enough to start the sequence, but not enough to pass the load check embedded mid-boot. The device stalls or reboots at the SonoScape logo. Charge the replacement cell fully before first installation and let the charger reach 100% before inserting — do not install mid-charge.

Charge indicator stalls below 100% on first charge cycle

On a new Li-ion cell, the SonoScape charge IC applies a conservative current limit during the first charge pass. This is normal — the charge controller has no capacity history for the cell and uses a reduced termination threshold. The indicator may stop at 95–98% and the device may report "battery not full." Run one complete charge-discharge cycle and the charge IC recalibrates its termination point. After that cycle, the indicator should reach 100% consistently at approximately 16.8V measured at the pack terminals.

Frequently Asked Questions

The SonoScape E2 alarms "low battery" immediately after the replacement came off a full charge — what's happening?

The BMS on the E2 checks cell voltage against a learned capacity profile at startup. A brand-new cell has no charge history, so the BMS applies its most conservative threshold and can flag low battery even at full charge. Run one complete charge-discharge cycle — full charge, normal use until the device prompts shutdown, then a full charge again. After that cycle, the BMS calibrates to the new cell and the alarm clears.

The ultrasound shuts off unexpectedly mid-scan during the first few uses — is the battery faulty?

Not necessarily. The imaging load on the E2 spikes sharply when transducer gain and depth are increased simultaneously. New Li-ion cells have slightly elevated internal resistance in the first 5–10 cycles, which causes a momentary voltage sag under that peak draw. The BMS reads the sag as under-voltage and triggers a protective cutoff. This behaviour typically resolves after 8–10 full cycles as internal resistance drops. If cutoffs persist past cycle 10, check that the pack terminals are clean and making full contact — measure pack voltage at load; it should hold above 13.5V during active scanning.

The SonoScape self-test returns a battery fault error after swapping in the new cell — how do I clear it?

This fault is almost always a BMS learn-cycle issue, not a defective cell. The E2 self-test compares real-time BMS data against stored baseline values from the previous pack — a new cell has no stored baseline. Power the device off completely, leave it off for 60 seconds, then power on and allow the full self-test to finish without interruption. If the fault persists, charge the battery to 100%, confirm the terminal voltage reads 16.8V, then repeat the full boot sequence — the self-test should pass once the BMS completes its first full verification cycle.
