Building a robust kit for a heavy camera body can quickly deplete your equipment budget if you only purchase original manufacturer accessories. The Wasabi Power LP-E4 / LP-E4N offers an impressive performance-to-price ratio that makes it easy to stock up on multiple spares. During my testing, I found that its real-world capacity actually matched or slightly exceeded aging OEM packs, providing ample runtime for extended event coverage and street photo walks. It drops seamlessly into the battery chamber without binding and charges correctly using both stock and third-party dual chargers. While it lacks the absolute precision of Canon’s proprietary microchips—occasionally causing the battery gauge to drop a bit unevenly near the end of its charge—it handles high continuous burst rates remarkably well. If you need to kit out a multi-camera shoot without spending a fortune, this is your best option. However, absolute purists who need flawless firmware reporting across multi-year lifespans might still want to lean toward the OEM choice.
- Outstanding price-to-capacity ratio for building a multi-battery kit
- Slightly higher rated capacity on paper than standard factory units
- Fully compatible with OEM charging hardware and camera terminals
- Battery percentage meter can occasionally step down non-linearly
- Shorter overall lifecycle longevity compared to genuine Canon cells

Finding a reliable secondary power source when your main battery depletes on location is crucial, but it shouldn’t require breaking the bank. The Kastar LP-E4 LP-E4N Replacement Battery targets photographers who need an inexpensive contingency pack to keep in their bag for emergencies. In my testing, it powered the EOS-1D C Mark II through light portrait sessions and general walkaround shooting without throwing error codes. The advertised capacity is generous, though I noticed actual longevity under heavy video loads fell slightly short of the OEM benchmark. Fitment in the vertical battery slot was snug, requiring a firm push to click into place, but locking mechanisms held secure. It does tend to self-discharge faster when left sitting in a gear bag for weeks compared to premium cells, so you will want to top it off before heading out. If you are a casual hobbyist or simply need a low-cost backup cell for occasional use, this budget option delivers functional performance for very little money.
- Extremely affordable price point for tight budgets
- Acceptable performance for light shooting and backup utility
- Includes standard protective terminal covers
- Noticeable self-discharge rate when stored unused for extended periods
- Build quality and outer plastic shell feel less refined

Frequently Asked Questions
Will using a third-party battery damage my Canon EOS-1D C Mark II?
Generally, no, provided you choose reputable third-party brands that include proper safety circuitry. Avoid extremely cheap “no-name” cells from unverified marketplaces, as these often lack thermal protection and may cause the camera to overheat or experience voltage spikes that could affect sensitive electronic components over time.
How do I choose between an OEM Canon battery and a high-end third-party alternative like Patona?
Choose the Canon OEM battery if you need absolute, guaranteed communication with the camera’s firmware and maximum longevity for professional studio work where zero failures are acceptable. Opt for the Patona Platinum if you want 95% of that performance and reliability at a lower price point for a large, multi-battery setup.
Is it a mistake to use older LP-E4 batteries with the EOS-1D C Mark II?
It is not necessarily a mistake, but you should be aware that the original LP-E4 (non-N version) has significantly lower capacity and older cell chemistry. It will work, but you will notice much shorter runtimes, and the camera may not report accurate battery health or shot counts as precisely as it does with the newer LP-E4N packs.
How many batteries should I carry for a full 10-hour day of 4K shooting?
For a full day of 4K production, I recommend carrying at least four fully charged batteries. The EOS-1D C Mark II is a power-hungry beast, especially when using the rear screen for continuous monitoring; having a rotation of four packs ensures you never have to stop shooting to wait for a recharge.
When is the best time to buy spare batteries for my camera?
Always purchase your spares at least two weeks before a major project begins. Batteries contain chemical components that should be tested and “cycled” (fully charged and discharged) at least once before you rely on them in the field to ensure they hold their charge and communicate correctly with the camera.
Final Verdict
If you are a professional working on high-stakes sets, the Canon LP-E4N is the only choice to ensure zero downtime. For those building a multi-camera kit on a budget, the Wasabi Power packs offer the most practical features-per-dollar. Casual hobbyists looking for an inexpensive emergency backup should stick with the Kastar, while high-end shooters wanting premium Japanese cell reliability without the full OEM markup should choose the Patona Platinum. As battery technology continues to evolve, look for manufacturers to further improve energy density and thermoregulation to support the next generation of power-hungry hybrid mirrorless and cinema systems.
