2010Batteries/Power forum

16 years old. Gear and prices may have changed since.

GlobalMediaPro Li160A batteries are rated for a maximum continuous power draw of 79 watts, which is insufficient for high-power applications like steadicams that may draw close to 100 watts when operating multiple accessories simultaneously.
The Li160A battery suddenly cuts power at approximately 12.6 volts with minimal warning, whereas some competing batteries provide voltage warnings starting around 11.7 volts.
GlobalMediaPro offers higher-capacity alternatives such as the Li230A (rated for 100 watts) and HW series batteries that better support power-hungry equipment configurations.
Multiple users report successful long-term performance from GlobalMediaPro batteries when used within their power specifications, with some batteries operating reliably for 5+ years.
The fuel gauge indicator on GlobalMediaPro batteries often displays zero charge while the battery still retains 13-14 volts when measured with an external meter, making the fuel gauge unreliable for determining actual remaining power.
GlobalMediaPro batteries are manufactured in China by multiple contract manufacturers and rebranded by various distributors under different label names, with consistent quality across these variants.
Power requirements must be calculated separately from energy capacity - a battery with lower total energy storage may have a higher continuous power output rating, making it more suitable for certain applications than a larger-capacity battery with lower power limits.

Early user reports from 2010 involved a faulty steadicam system leaking power, which was later identified as the root cause rather than a battery defect.
The discussion includes experiences across different battery models (Li90, Li95, Li160, Li190, Li230, HW series) purchased at different times, making direct model-to-model comparisons difficult.
Some positive experiences come from using the batteries within professional camera rigs that separate power distribution among components, while problems occurred in direct on-camera configurations.
The claim about all batteries being manufactured by one Chinese company was reported as secondhand information from a trade show conversation.
