Battery Care Tips
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
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.

Ermila Bellina — 3.2V LiFePO4 Replacement Battery
This is a 3.2V 1800mAh LiFePO4 replacement battery for the Ermila Bellina cordless hair clipper. It restores wireless operation when the original cell has lost charge capacity. Dimensions are 55.10 × 33.40 × 24.60mm — measure your existing cell before fitting.
- Ermila Bellina platform fit: The Bellina runs a single LiFePO4 cell at 3.2V nominal. That flat discharge curve is intentional — LiFePO4 holds voltage steady under motor load longer than Li-ion, which suits the variable draw of a clipper motor during dense or coarse hair passes.
- Bench tested on actual hardware: We cycled this cell through full charge and load discharge. The BMS held cutoff correctly at low-voltage threshold and accepted charge current without tripping protection. Cell temperature stayed within normal range across the discharge cycle.
- Port drying before charge: If the Bellina has been rinsed or used in humid conditions, dry the charging contacts completely before connecting the charger. Moisture bridging the contacts can trigger a BMS protection fault — the device then reports as a dead battery rather than a charging error.
Shaver motor speed dropping before the indicator shows low
LiFePO4 has a flat voltage curve, but an aged or degraded cell still sags under the short high-current spikes the Bellina motor produces during cutting resistance. The indicator reads state-of-charge from resting voltage — it hasn't updated yet when the motor is pulling current. The result is a speed drop that feels like a dead battery while the indicator still shows charge remaining. A fresh cell with full capacity eliminates this sag under load.
Capacity drift from daily partial cycling on the Bellina
LiFePO4 handles partial cycles better than Li-ion, but the Bellina's charge indicator calibration can still drift if the cell is never fully cycled. The gauge is calibrated against a full charge-to-cutoff reference point. Repeated top-ups without a complete discharge mean the indicator loses its baseline and starts cutting off earlier than the actual cell capacity warrants. Run the clipper to BMS cutoff once, then charge fully to 3.65V to reset the reference.

Frequently Asked Questions
My Bellina clipper slows down noticeably mid-cut but the battery indicator still shows charge — what's causing that?
Voltage sag under motor load is the cause. When the clipper hits resistance — thick or coarse hair — the motor draws a short current spike the aged cell can't sustain without the voltage dipping. The indicator reads resting voltage, not load voltage, so it hasn't caught up. A replacement cell with full capacity handles those spikes without the voltage drop.
The Bellina stopped charging after I rinsed it — dock light comes on but the battery won't take a charge.
Moisture bridging the charging contacts triggers a BMS protection trip on the cell. The device reads this as a battery fault, not a water fault, which is why the dock light still activates. Dry the charging port thoroughly — compressed air or a dry cloth — leave it for at least an hour, then reconnect. If the fault clears, the cell is fine; if not, the BMS protection latch may need a full discharge to 2.5V before it resets.
The Bellina clipper feels warm near the body during longer grooming sessions — is that a battery problem?
Some warmth is normal. The Bellina's compact housing concentrates heat from both the motor and the discharging cell in a small space. Excessive heat — too hot to hold comfortably — usually means the cell is working harder than it should, often because capacity has faded and the BMS is drawing higher current to maintain motor speed. Check whether the warmth started appearing around the same time as reduced run performance — if yes, the cell is the likely cause.
