V-LFP-12-80 Fusion Lithium 80AH 12V Deep Cycle Battery

V-LFP-12-80 Fusion Lithium Iron Phosphate

12V 80Ah Deep-Cycle Battery

Lightweight, high-cycle LiFePO₄ power for 4WD, marine, RV and solar systems. The Fusion V-LFP-12-80 delivers stable voltage, rapid charging and long service life in a compact, maintenance-free design — ideal for deep-cycle use where reliability counts.

Why Choose Fusion LiFePO₄?

• Up to 2000+ cycles at 80% depth of discharge
• Built-in Battery Management System (BMS) for cell balancing and protection
• Lightweight design – around 50% lighter than AGM equivalents
• Fast recharge and consistent voltage under load
• Maintenance-free, non-spill and vibration-resistant
• Safe LiFePO₄ chemistry – no thermal runaway or gassing

Specifications

Ideal For

• 4WD dual-battery systems
• Caravans, camper trailers & motorhomes
• Marine deep-cycle house banks
• Off-grid solar storage
• Portable power systems

Small Battery Bank Examples

Build out capacity or voltage safely with matched, identical batteries. Keep interconnects short and equal length.

(Parallel, 12V 160Ah)
[+ Batt A -]
   |     |
   |     |
[+ Batt B -]
Take system + from Batt A positive and system – from Batt B negative for best balance.

(Series, 24V 80Ah)
[+ Batt A -]───[+ Batt B -]
System + at Batt A +, System – at Batt B –

(2S2P, 24V 160Ah)
Make two series pairs, then parallel the pairs:
([A +]──[A –])  ∥  ([B +]──[B –])
System + from A+, System – from B–
    

Wiring Notes (Recommended Practice)

• Use identical batteries (model, age, state of charge) when building banks.
• Balance leads: take main positive from one end of the bank and main negative from the opposite end.
• Protect each battery/string with appropriate fusing close to the terminal.
• Cable sizing depends on current and run length — ask us if unsure.
• Charger/MPPT profile: Lithium/LiFePO₄ with absorption ≈14.4–14.6V (per 12V block).
• Check manufacturer guidance for series/parallel limits and BMS requirements.

Charging & Storage Tips

• Use a LiFePO₄-compatible charger (14.6V max, 13.8V float)
• Recharge after use; avoid long-term storage below 12.8V
• Store in a cool, dry place between 10°C–30°C

Quick FAQ

Q: Can I use this as a cranking battery?
A: No — this is a deep-cycle model, designed for steady discharge applications, not engine starting.

Q: Is it compatible with solar charging?
A: Yes — use any MPPT or PWM solar controller with a lithium profile or adjustable set-points.
