IMET M880 KRON Crane Remote Compatible Battery 3.7V 3200mAh

IMET M880 KRON / ZED / THOR2 / ZEUS2 — 3.7V Li-ion Replacement Battery (BE3600LI)

This 3.7V 3200mAh Li-ion battery replaces the BE3600LI cell in IMET wireless crane remote controls. It fits the M880 KRON, ZED, THOR2, ZEUS2, and compatible models in the same series. Voltage and capacity match OEM spec exactly — no modification needed at the remote's battery contacts.

• M880 KRON / ZED / THOR2 / ZEUS2 platform fit: These IMET remotes share the same single-cell 3.7V architecture, battery bay dimensions (54.20 × 54.50 × 21.80mm), and contact layout. The BMS handshake in each model communicates directly with this cell format, so the remote's charge indicator and low-battery warning behave as expected after swap.
• Bench tested on actual hardware: We cycled this cell through full charge and simulated solenoid-trigger draws on the bench. The BMS held voltage above the 3.0V cutoff threshold under repeated activation loads without tripping into protection mode.
• Monthly charge during crane downtime: IMET remotes on overhead cranes often sit idle for weeks between jobs. If the cell drops below 2.5V — roughly 30 days of self-discharge from fully depleted — the BMS enters deep-discharge lockout. Connect the remote to its charger for at least 30 minutes before attempting to power on after any long idle period.

Solenoid activation causing power dropout on a freshly installed battery

When a crane remote triggers a solenoid or relay, the inrush current spike can briefly exceed the BMS overcurrent threshold on a cold or partially charged cell. The remote cuts out mid-operation — not because the battery is faulty, but because the BMS tripped as a protective response. A full charge before first use raises resting voltage to 4.2V, which gives the cell enough headroom to absorb that inrush spike without hitting the cutoff. If dropouts continue after a full charge cycle, check that the battery contacts are clean and seating flush — a resistive contact amplifies the voltage sag under load.

Remote showing "low battery" immediately after a new cell is installed

Replacement cells ship at storage voltage — typically 3.6–3.7V — not at full charge. IMET remotes read cell voltage directly to determine battery status, so a cell at storage voltage registers as low or partially depleted on the remote's indicator. This is not a faulty battery. Connect the remote to its OEM charger and charge until the indicator shows full — resting voltage should reach 4.15–4.2V before use.
