The GaiaRay CALB LiFePO4 3.2V 200Ah battery is a rechargeable lithium iron phosphate battery designed for high-capacity energy storage in solar systems, motorhomes, and marine applications. With 6,000+ life cycles, thermal stability, and a maintenance-free design, it outperforms lead-acid batteries in longevity, safety, and depth of discharge (80-90% usable capacity). Its 200Ah rating provides 640Wh of energy per cell, scalable for custom configurations.
What Is a DC to DC Lithium Battery Charger and How Does It Work
What Safety Features Are Built Into the GaiaRay CALB 3.2V 200Ah Battery?
CALB’s proprietary LiFePO4 chemistry eliminates thermal runaway risks, with a stable cathode structure that resists combustion. Built-in BMS protects against overcharge (3.65V cutoff), over-discharge (2.5V cutoff), and short circuits. The UL1973-certified design includes pressure relief vents and flame-retardant casing. Internal cell balancing ensures ±20mV voltage tolerance across cycles.
The battery’s multi-layer protection system includes ceramic separators that withstand temperatures up to 150°C without shrinkage. Its cell-to-pack (CTP) design reduces interconnection points by 40%, minimizing failure risks in high-vibration environments. The aluminum alloy casing features IP67 waterproofing and includes gas recombination technology to prevent electrolyte leakage. Third-party testing confirms zero thermal runaway propagation between cells even under nail penetration tests.

How Does the GaiaRay CALB LiFePO4 Battery Compare to Traditional Lead-Acid Batteries?
The GaiaRay CALB LiFePO4 battery offers 4x the lifespan of lead-acid batteries (6,000 vs 1,500 cycles) and 50% more usable capacity. Unlike lead-acid, it maintains stable voltage output below 20% charge and operates efficiently in -20°C to 60°C temperatures. It’s 70% lighter (5.6kg vs 19kg for 200Ah lead-acid) and charges 3x faster with no memory effect.
DEESPAEK 12V 200Ah LiFePO4 Battery for RV, Solar, and Trolling Motor Use
Which Applications Benefit Most From This 200Ah LiFePO4 Battery?
• Solar off-grid systems: 48V 10kWh setups require 16 cells in series
• Marine trolling motors: 24V systems use 8 cells (25.6V nominal)
• RV house batteries: 12V configurations (4 cells) power 3,000W inverters
• Telecom backup: 48V DC systems with 95% round-trip efficiency
• Industrial UPS: Parallelable up to 4 units for 800Ah capacity
How to Properly Install and Maintain the GaiaRay CALB Battery Pack?
Use M8 bolts for terminal connections (25Nm torque limit). Maintain 2mm spacing between cells for thermal expansion. Storage at 50% SOC extends shelf life to 5+ years. CALB recommends 0.5C charging (100A max) with CC/CV profiles. Annual capacity tests using 0.2C discharge maintain warranty compliance. Avoid series-parallel mixes beyond 4P configurations.
What Are the Cost Savings Over 10 Years Compared to AGM Batteries?
Initial cost: $320 (LiFePO4) vs $180 (AGM) per 200Ah unit
Cycle cost analysis:
• LiFePO4: $320/6,000 cycles = $0.053 per cycle
• AGM: $180/500 cycles = $0.36 per cycle
Total 10-year savings: $4,120 for 8,000 cycles (accounting for 3 AGM replacements). ROI achieved in 18 months for daily cycling applications.
| Metric | LiFePO4 | AGM |
|---|---|---|
| Cycle Life | 6,000 | 500 |
| Energy Cost/Cycle | $0.053 | $0.36 |
| Weight (kg) | 5.6 | 19 |
When calculating total ownership costs, consider the LiFePO4 battery’s zero maintenance requirements versus AGM’s monthly equalization charges. Solar users save an additional $120/year by eliminating water refills and terminal cleaning. The 92% depth of discharge capability reduces required battery bank size by 30% compared to AGM’s 50% limit.
“The CALB LFP cells in GaiaRay’s battery use a stacked electrode design that reduces internal resistance by 22% compared to wound cells. This translates to 98% charge efficiency even at -10°C. For marine applications, the nickel-plated terminals resist saltwater corrosion better than standard brass.”
