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.

Verizon Ellipsis Jetpack MHS700L — 3.8V Li-ion Replacement Battery (FWCR700BATS)
This is a 3.8V, 2100mAh Li-ion battery for the Verizon Ellipsis Jetpack and Ellipsis Jetpack 4G mobile hotspot devices, including the MHS700L and MHS700LPP. It replaces OEM part numbers FWCR700BATS and ICP565156A. When the original cell degrades, the hotspot loses the ability to hold a charge long enough to stay useful away from a wall outlet — this swap restores that.
- MHS700L and MHS700LPP compatibility: Both variants run the same 3.8V power rail and use the same physical connector and BMS handshake protocol. One battery covers both without any adapter or firmware change.
- Bench tested on actual hardware: We ran this cell under simultaneous WiFi client load and active LTE modem draw. The BMS held voltage regulation steady across the load curve and did not trigger a false low-voltage cutoff during connection bursts.
- Cellular signal and heat management: When connected devices are far from the hotspot, the cellular radio runs at maximum output power. Keep the Jetpack within a few metres of connected devices — the reduced transmit power lowers heat buildup at the battery, which directly affects how the cell ages over charge cycles.
Why the Ellipsis Jetpack drops clients mid-session under full connection load
The Jetpack runs two power-hungry systems at once — the LTE modem and the WiFi radio. When all available client slots are active, combined draw creates voltage sag that can dip below the BMS protection threshold momentarily. An aged or degraded cell has higher internal resistance, which makes that sag worse and more frequent. A fresh cell at full rated capacity handles the combined load without hitting the cutoff point. If drop-outs persist after a battery swap, check whether the hotspot is in a low-signal area — the modem compensates by pushing radio output harder, increasing draw further.
Jetpack shows a charge indicator but won't boot after sitting unused for weeks
Li-ion cells self-discharge during storage, and the Ellipsis Jetpack firmware will refuse to boot if battery voltage sits below approximately 3.0V — even if the charge LED flickers. The BMS interprets sub-threshold voltage as a fault state rather than a dead cell. Connect the device to a wall charger and leave it for at least 20 to 30 minutes before attempting a power-on — the charger delivers a low-current recovery charge that brings the cell back above the minimum boot voltage. If the device still won't power on after that, check the USB cable and charging port for debris before replacing the battery.

Frequently Asked Questions
My Ellipsis Jetpack kicks connected devices off WiFi every few minutes — could the battery be causing that?
Yes, this is a known failure mode with degraded cells. When multiple devices are connected simultaneously, the combined LTE modem and WiFi radio draw causes voltage to sag momentarily — a worn battery with high internal resistance dips below the BMS protection threshold and forces a brief reset. We reproduced this on the bench with a degraded original cell and saw clean, stable output with the replacement under the same multi-client load. Replace the battery first before assuming a firmware or signal issue.
The Jetpack battery drains noticeably faster since I moved to an area with weak 4G coverage — is that normal?
It is. In poor signal areas the LTE modem increases transmit power to maintain the cellular connection, which is one of the highest-draw states the device can reach. Add two or three active WiFi clients on top of that and total current draw can nearly double compared to idle. The battery itself is not failing — the operating environment is pulling it harder. If this is a regular location, use the hotspot closer to a window or elevated position to improve signal strength and reduce modem output power.
My Jetpack sat in a drawer for a few months and now won't power on at all — is the battery dead?
Not necessarily dead, but likely deep-discharged below the minimum boot voltage of around 3.0V. The Jetpack firmware blocks startup below that threshold as a BMS protection measure, so the device appears completely unresponsive even if some charge remains. Plug it into a wall charger — not a PC USB port — and leave it for 30 minutes without pressing the power button. After that recovery window, attempt a boot. If it still won't start, measure the charging port for debris or damage before writing off the battery.
