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.

Ritron Generation 3 LoudMouth Receivers — 11.1V Li-ion Replacement Battery (BP-LM-Li22)
This is an 11.1V, 2600mAh lithium-ion battery for the Ritron Generation 3 LoudMouth Receivers. It replaces OEM part BP-LM-Li22 in the receiver unit. Voltage, capacity, and connector position match the original specification.
- Generation 3 LoudMouth platform fit: The Gen 3 LoudMouth series runs an 11.1V three-cell Li-ion pack with a specific BMS handshake tied to the dock acceptance circuit. A mismatched voltage rail or missing BMS signal will trip the dock into fault mode, so cell count and BMS configuration both matter here.
- Bench tested on actual hardware: We cycled this pack through transmit-load draws and confirmed the BMS holds the output rail stable under sustained RF current spikes. Cell balancing across all three cells stayed within tolerance at full charge and at mid-state-of-charge.
- First insertion on a cold pack: If the charger dock shows a fault LED on first insertion, remove the BP-LM-Li22, wipe the contact strip with a dry cloth, and reseat firmly. The Gen 3 dock requires a clean contact cycle to complete the BMS handshake before charging begins.
Why the LoudMouth Gen 3 cuts out mid-transmission on a new BP-LM-Li22
A new pack ships at storage voltage — typically around 3.7V per cell, or roughly 11.1V total — not at full charge. When PTT is pressed, the transmit current draw spikes sharply. If the cells haven't been through a full charge cycle, internal impedance is higher than normal and the BMS may trip the output before the transmission completes. Charge the pack fully before the first use cycle. After one full charge, the BMS calibrates to the cell state and the cutout behaviour stops.
Bar indicator showing one fewer bar than expected after fitting the BP-LM-Li22
The Gen 3 LoudMouth uses a simple voltage-threshold bar indicator — each bar maps to a voltage window across the 11.1V pack. A new cell at storage voltage sits in the lower threshold band, so the radio displays one or two bars even though the pack isn't depleted. This isn't a faulty cell or a mismatch. Put the pack on charge until the dock shows a full-charge status, then reinsert — the indicator will read correctly at 12.6V (4.2V per cell at full charge).

Frequently Asked Questions
The charger dock fault LED won't clear after I inserted the new BP-LM-Li22 — what's causing it?
The Gen 3 dock checks for a minimum acceptance voltage before it starts charging. If the new pack has been in storage, the cells may sit below the dock's acceptance threshold, triggering a permanent fault LED. Remove the pack, wipe the gold contact strip with a dry cloth, and reseat it firmly to ensure the BMS handshake completes. If the fault LED persists, the pack needs a recovery charge — use a standalone Li-ion charger set to 11.1V at 0.5A to bring the cells above 10.5V total before returning it to the dock.
The LoudMouth drops to noticeably lower transmit power partway through a long shift — is this the battery?
Sustained RF output draws steady current across the full shift, and voltage sag increases as the pack discharges toward the lower cell threshold. The radio's power control circuit reduces TX output when the supply voltage drops below its operating floor — typically around 10.5V for an 11.1V pack. This isn't a fault; it's the radio protecting the final RF stage. Charge the BP-LM-Li22 before a long shift and confirm resting voltage reads at or above 12.0V before going on air.
The pack was stored in the receiver for several months unused and now the radio won't power on at all — is the battery recoverable?
Extended storage inside a receiver that draws standby current can pull an 11.1V Li-ion pack below the BMS recovery threshold — around 8.4V total (2.8V per cell). Below that level, the BMS locks out the output circuit entirely to prevent cell damage. Remove the pack and use a standalone Li-ion charger with a recovery or boost mode to raise each cell above 3.0V. Once total pack voltage reaches 9.0V or above, the BMS will re-initialise and accept a normal charge cycle from the dock.
