What the thread found

• Mixing lithium-ion and nickel-cadmium batteries in series requires diodes to prevent the lithium-ion cells from charging the nickel-cadmium cells.
• Some sled designs use diodes to manage mixed battery chemistries, allowing simultaneous operation of different battery types without damage.
• Fully regulated power supplies in certain sleds maintain consistent output voltage to connected devices regardless of input battery voltage or chemistry.
• A regulated supply that outputs consistent voltage reduces wasted power dissipation as heat when fresh batteries deliver excessive voltage.
• Regulated power systems allow operation with a single battery, trading runtime duration for reduced system weight and cost.
• Multiple batteries operating through a regulated voltage supply discharge at the same rate, simplifying battery change scheduling and extending overall battery lifespan.
• Nickel-cadmium batteries provide higher peak current delivery for voltage spikes that might cause lithium-ion batteries to shut down under high load.
• Combining nickel-cadmium and lithium-ion batteries with proper regulation enables extended runtime exceeding twenty magazine loads without battery changes.
• Equal discharge rates across multiple battery types through regulation improves battery longevity by distributing workload evenly.

Depends on

• Discussion focuses on sleds and camera systems from around 2005, technologies and specific models may have evolved.
• Author shares experience with specific models (Nexus, Evolution, XCS, Proformer, Dionic) which may not represent all available systems.
• The 435 and 435 ES camera compatibility issues with lithium-ion batteries are mentioned but not fully explained.
• No technical specifications provided for voltage regulation ranges or efficiency metrics.
