VRLA, Lithium-Ion, Flywheel, Fuel Cell — heres what you need to know about each technology.
## VRLA (Valve-Regulated Lead-Acid)
**The traditional choice.**
Pros:
– Low upfront cost
– Well-understood technology
– Easy recycling
Cons:
– 5-7 year lifespan
– Heavy
– Temperature sensitive
## Lithium-Ion
**The modern standard.**
Pros:
– 10-15 year lifespan
– Lightweight
– Fast charging
– Better high-temp performance
Cons:
– Higher upfront cost
– Requires BMS
– Recycling infrastructure developing
## Flywheel (UPSonic)
**The niche player.**
Pros:
– Instant response
– Long lifespan (20+ years)
– Low maintenance
Cons:
– Limited runtime
– High cost per kWh
– Requires pressurized containment
## The Future: Fuel Cells
Emerging technology for:
– Long runtime (8-24 hours)
– Clean power
– Rapid refueling
Still expensive but improving rapidly.
## Our Recommendation
For 2026: **Lithium-ion** for most applications
