About this replacement
Urovo i60 / i60XX — 3.7V Li-ion Replacement Battery (DRN51133367)
This 3.7V 3200mAh Li-ion battery replaces the OEM pack in the Urovo i60 and i60XX mobile data terminals. These are rugged handheld computers used for field data collection, surveying, and equipment testing. Capacity figures are taken directly from product data — 11.84Wh total energy.
- i60 and i60XX compatibility: Both variants share the same voltage rail, connector pinout, and BMS handshake protocol. Swapping between them does not require firmware changes or hardware modification — the BMS reads cell state the same way across both units.
- Bench tested on actual hardware: We cycled this pack through the i60's power management routines, including probe initialisation events and sustained sensor load. The BMS held stable under the short current spikes that accompany peripheral startup and did not trip into protection mode.
- First-use calibration on the i60: After installing this pack, run a full calibration cycle through the i60 instrument menu before field deployment. The terminal maps battery state during calibration — skipping this causes the low-battery indicator to trigger early on the first measurement session, even with a full charge.
BMS lockout after the i60 sat unused in a carry case for months
Li-ion cells self-discharge slowly over storage. If the i60 sits unused long enough, cell voltage can drop below the BMS recovery threshold — typically around 2.5V per cell. At that point the BMS locks the pack to prevent damage, and the terminal shows no charge activity even when connected to a charger. To recover, connect to a USB-C charger and leave it for 30–60 minutes without powering on. Most BMS circuits include a trickle pre-charge path that will bring the cell voltage back above the recovery threshold and re-enable normal charging.
i60 shuts down during USB data transfer to PC with battery showing charge
USB data transfer adds a second load on top of the active processor and display draw. If the cell voltage sags under this combined load, the BMS can trip the under-voltage cutoff even when the fuel gauge was reading a healthy percentage moments before. This is more common with aged cells but can also appear with a new pack if the terminal's battery calibration data is stale. Run the calibration cycle first, then retest the transfer. If it shuts off below 3.6V on the cell, that is a BMS protection event — not a faulty pack.
