Replacement Li-Ion battery for Canon PowerShot

The Kastar BP-511 is a 7.4 V lithium-ion pack rated at 2600 mAh and 19.24 Wh. It replaces Canon BP-511, BP-511A and several related part numbers. The single-battery pack fits PowerShot G5 Pro, G6, Pro 1, Pro 90 and numerous EOS models listed by the supplier. Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating.

Sustained shooting performance

The 2600 mAh capacity delivers longer run time than lower-capacity alternatives, letting you capture extended sequences without swapping cells. The lithium-ion chemistry maintains a stable voltage curve through most of the discharge cycle, so the camera meter remains accurate during continuous use. Protection electronics prevent sudden shutdown caused by deep discharge or current spikes when the flash fires repeatedly.

Thermal behaviour and power draw

The pack meets UL 1642 and CE safety standards, indicating controlled temperature rise under normal load. Internal safeguards limit current and voltage if the cell approaches thermal limits, reducing the chance of overheating during long sessions. No active cooling is required; the battery relies on the camera body for passive heat dissipation. Normal charging proceeds through compatible Canon CB-5L or CG-580 chargers.
