Q1. What is the 5.4V 10F module used for?
A: It is a ready-made two-cell series EDLC module for energy storage, backup power and pulse loads - typical uses include RTC/SRAM backup, smart-meter last-gasp power, GPS tracker transmit bursts, energy-harvesting storage and relay/motor pulse actuation.
Q2. Can I connect modules in series or parallel?
A: Yes. Connect in parallel to add capacitance and current capability directly; connect in series for higher voltage but add external balancing so no cell exceeds its 2.7V rating (module terminal voltage must stay ≤ 5.4V).
Q3. How long does it last?
A: The module is rated for 500,000 charge-discharge cycles at 25°C. At 20 cycles per day that is over 60 years - cycle count, not calendar aging, dominates the service life, far longer than batteries.
Q4. What temperatures can it handle?
A: -40°C to +70°C for both operation (top of cell) and 0V storage, with normal performance at -40°C where lithium batteries cannot work. A high-temperature (HT) series rated to +85°C is available on request.
Q5. How do I charge it?
A: Charge with a simple current-limited DC source up to 5.4V - no memory effect and no complex charge algorithm. Keep continuous current within 4.6A (14.2A maximum at 25°C) and never exceed 5.4V across the module terminals.
Q6. How is it shipped and certified?
A: Modules ship with leads protected against shorting, pearl-foam cushioned in cartons, certified to UN38.3 for worldwide air/sea transport; MSDS and CE documents are available on request. MOQ is 20 pcs, samples negotiable.
