About this replacement
Triplett CamView IP Pro / TRI-807x Series — 7.4V Li-Polymer Replacement Battery (WG-B16)
This is a 7.4V 3450mAh lithium-polymer replacement battery for the Triplett CamView IP Pro and TRI-807x series thermal imaging cameras, including the TRI-8070 and TRI-8071. It replaces OEM part numbers WG-B16, 37-71, and 37-105. Field technicians use these cameras for electrical diagnostics, building envelope surveys, and HVAC inspections where continuous power matters.
- CamView IP Pro and TRI-807x compatibility: These models share the same battery bay geometry, connector pinout, and BMS handshake protocol. The camera's power management circuit reads pack voltage and protection status over the same interface across the TRI-8070, TRI-8071, and CamView IP Pro variants, so one pack covers the full platform.
- Bench tested on actual hardware: We cycled this pack through the CamView IP Pro's full boot sequence, IR sensor initialisation, and sustained imaging load. The BMS held stable under the current spike at sensor power-up and maintained clean voltage delivery through extended thermal survey sessions without tripping a protective cutoff.
- Post-install calibration on TRI-807x cameras: After fitting this pack, run a full calibration cycle through the instrument menu before heading into the field. The camera maps battery state during calibration — skipping it causes premature low-battery warnings to appear within the first measurement session even when the pack is well charged.
CamView IP Pro shutting down mid-thermal survey with no warning
This happens when the IR sensor array draws a short current spike during a continuous imaging cycle and the BMS interprets it as an overcurrent fault. Older or partially degraded cells can't absorb the transient, so the protection circuit opens and cuts power instantly. A fresh lithium-polymer pack with intact cell capacity handles these spikes without triggering the cutoff. If shutdowns persist after fitting this battery, check that the camera firmware is current — some TRI-807x firmware revisions adjusted the power draw profile to reduce peak current demand on the pack.
Pack will not charge after the camera sat unused for several months
Lithium-polymer cells that self-discharge below roughly 2.5V per cell enter a deep-discharge state where the BMS locks out charging as a safety measure. The charger sees a pack that appears dead and stops the charge cycle before it starts. To recover, connect the pack to the OEM charger and leave it for 15–20 minutes — many BMS circuits include a trickle pre-charge stage that slowly brings cells back above the 3.0V recovery threshold before switching to normal charge. If the charger shows no activity at all after 30 minutes, the cells have dropped below the recovery floor and the pack needs replacement.
