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

[+ 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.
