What Is Battery Product 12-125-17 Used For?
Battery Product 12-125-17 is a 12V 125Ah lithium iron phosphate (LiFePO4) deep-cycle battery designed for renewable energy storage and marine/RV applications. With a 4000+ cycle lifespan at 80% DoD, it provides stable power for off-grid solar systems, trolling motors, and backup power setups. Its built-in BMS ensures protection against overcharge, over-discharge, and short circuits, while the compact IP65 design allows vertical or horizontal installation in tight spaces.

What are the key technical specs of 12-125-17?
This LiFePO4 battery delivers 12.8V nominal voltage, 125Ah capacity (1.6kWh), and 200A max continuous discharge. With a 90% efficiency rate and -20°C to 60°C operating range, it outperforms lead-acid alternatives in cold starts. Pro Tip: Use temperature-compensated charging above 45°C to prevent BMS-triggered shutdowns.
Beyond voltage ratings, the 12-125-17’s modular design allows parallel connections up to 4 units for 48V/500Ah systems. Its 35kg weight is 60% lighter than equivalent AGM batteries—critical for marine applications where every kilogram impacts fuel efficiency. Ever wonder how it maintains stable output? The 3-level cell balancing system corrects voltage deviations ≥30mV, crucial during partial state-of-charge cycling in solar setups. For example, RV owners report 3-day autonomy powering 12V fridges (150W) and LED lighting (50W).
| Feature | 12-125-17 | AGM Equivalent |
|---|---|---|
| Cycle Life (80% DoD) | 4,000 | 600 |
| Weight | 35kg | 85kg |
| Charge Time | 4hrs (50A) | 12hrs |
Which devices work best with this battery?
Optimized for solar storage, trolling motors, and inverter backups, the 12-125-17 handles surge loads up to 400A for 5 seconds. Its low self-discharge (3% monthly) suits seasonal applications like vacation cabins. Pro Tip: Pair with 100W+ solar panels to avoid depth-of-discharge exceeding 80% in cloudy conditions.

Practically speaking, this battery shines in two scenarios: off-grid power banks and marine thrusters. The 200A continuous output runs 12V inverters up to 2400W—enough for microwaves or power tools. But what happens if you connect undersized cables? Voltage drops below 11V during 200A draws could trigger BMS cutoff. Anglers using Minn Kota trolling motors (80lbs thrust) achieve 8+ hours runtime versus 4 hours with AGM. Transitional phrase: While peak performance impresses, the real advantage is longevity—replacing 5-7 lead-acid cycles annually with zero maintenance for a decade.

FAQs
Yes, but update your charger—LiFePO4 requires 14.6V absorption vs AGM’s 14.4V. Most modern RV converters have lithium modes—check settings first.
Does cold weather affect capacity?
At -20°C, capacity drops to 85% but recovers when warmed. Use self-heating models (like Redway’s Arctic Edition) for <-10°C operations.
How to monitor battery health?
Track capacity via voltage: 13.3V=100%, 12.8V=50%, 12.5V=20%. For precise readings, add a shunt-based monitor (e.g., Victron BMV-712).
