VATRER POWER

About VATRER POWER

VATRER POWER builds LiFePO4 (lithium iron phosphate) batteries and accessories for dependable, everyday DC power. Their packs emphasize stable voltage under load, high usable capacity, and protective battery management systems (BMS) for RVs, boats, golf carts, cabins, and backup applications.

Product Range

• 12V house batteries: Common choice for RVs, boats, and small off-grid systems. Select models include Bluetooth for state-of-charge and cell temperature visibility.
• 24V, 36V, 48V, 72V packs: Suited to higher-power inverters, trolling motors, and carts where higher voltage reduces current and cable size.
• 48V golf cart kits: Lightweight replacements for multi-battery lead-acid sets to improve range and reduce maintenance.
• Self-heating variants: Designed to protect cells when charging in cold conditions; useful for winter camping and high-altitude storage.

Key Advantages

• Protective BMS: Guards against over/under-voltage, over-current, short circuit, and temperature extremes.
• High usable capacity: LiFePO4 typically supports deeper routine discharge than lead-acid, enabling smaller, lighter banks for the same usable energy.
• Stable voltage: Flatter discharge curve helps inverters and sensitive electronics perform consistently.
• Low maintenance: No watering, venting, or equalization cycles.
• Optional Bluetooth: Real-time insights (SoC, temperature, cycles) reduce guesswork.

When to Choose VATRER POWER

• Choose if: You need reliable deep-cycle power for RV house loads, trolling motors, golf carts, weekend cabins, or home backup with quick solar/AC recharging.
• Avoid/consider alternatives if: You operate in severe cold without heating (lithium charging is restricted below freezing), need the lowest upfront cost (AGM may be cheaper initially), or require an engine starting battery (use a starting-rated battery rather than deep-cycle lithium).

Right-Size Your System

1. List loads: Note watts (or amps) and daily hours. Sum to daily Wh (or Ah).
2. Pick voltage: 12V for smaller systems; 24V/36V/48V where inverter size or cable runs benefit from lower current.
3. Size capacity: Target at least one day of use plus reserve. Plan around your typical depth of discharge (often 60–90% for LiFePO4).
4. Match inverter: Choose continuous wattage above your concurrent loads and confirm surge capacity for motors.
5. Plan charging: Combine solar (MPPT), AC charger, and—on vehicles—a DC-DC charger to protect the alternator.

Quick Runtime Examples (12V 100Ah battery at ~80% usable ≈ 960 Wh)

Actual runtimes vary by inverter efficiency, duty cycles, temperature, and wiring losses.

Charging and Integration Tips

• Use a lithium profile: Set your charger/MPPT to LiFePO4. Typical 12V bulk/absorb values fall in the 14.2–14.6 V range with short/disabled float (e.g., 13.4–13.8 V), but always follow your model’s datasheet.
• Cold charging: Do not charge below 0°C/32°F unless using a self-heating model approved for cold charging. The BMS should prevent unsafe charging, but plan around temperature limits.
• Alternators: Use a DC-DC charger to limit current and isolate the chassis battery. Size it to your battery and alternator (commonly 20–60 A per battery).
• Series/parallel: Only connect identical models. Follow the manufacturer’s series/parallel limits. Use busbars for balanced wiring.
• Fusing and wire: Fuse within 7 inches of the battery positive and at each charge source. Use appropriately sized cables (target ≤3% voltage drop on critical runs).

Pros and Cons

• Pros: High usable capacity, long cycle life potential, lower weight, quick charging, minimal maintenance, stable voltage.
• Cons: Higher upfront cost, cold-charge limits without heating, requires compatible chargers and correct system design.

Alternatives and Complements

• AGM lead-acid: Lower initial cost and tolerant of cold charging; heavier with less usable capacity and slower recharge.
• Keep a starter battery: For engines, use a starting-rated battery (lead-acid or lithium specifically designed for cranking).

FAQ

• Can I drop a LiFePO4 in place of my lead-acid? Yes, if your charging sources support a lithium profile and you add a DC-DC charger for vehicle alternators. Verify voltage set points and fuse appropriately.
• Do I need Bluetooth monitoring? Not required, but it helps manage loads, verify charge health, and diagnose issues without a shunt.
• How many cycles can I expect? It depends on depth of discharge, temperature, and charge settings. With sensible use, LiFePO4 commonly delivers thousands of cycles.
• Can I mix old and new batteries? Avoid mixing ages/capacities. If expanding, use matching models and fully charge/balance before linking.
• How should I store the battery? Store cool and dry at ~50–70% state of charge. Top up every 3–6 months or per the manual; disconnect parasitic loads.

Safety Notes

• Follow the product manual for voltage set points, series/parallel limits, and temperature ranges.
• Install proper fusing, secure the battery against movement, and protect terminals from shorting.
• Disable “equalize” modes not intended for lithium batteries.
