What Are Specs Of Dakota Lithium Battery?
Dakota Lithium batteries are high-performance LiFePO4 (lithium iron phosphate) cells designed for deep-cycle applications. Key specs include 12V/24V/36V configurations, capacities from 10Ah to 135Ah, 2000–5000+ cycles at 80% depth of discharge (DoD), and operation from -20°F to 140°F. Built with ruggedized cases and integrated BMS, they excel in marine, solar, and RV use, offering 30%–50% weight savings versus lead-acid. Charging voltages range from 14.4V (12V models) to 43.8V (36V).

What chemistry defines Dakota Lithium batteries?
Dakota uses LiFePO4 (lithium iron phosphate) chemistry, prioritizing safety and longevity. With thermal runaway resistance above 500°F, these cells avoid cobalt-based risks while delivering 2000+ cycles. Pro Tip: LiFePO4 maintains 80% capacity even at -4°F—ideal for off-grid setups.
LiFePO4’s stable cathode structure minimizes oxidative degradation, enabling a 10–15 year lifespan under 80% DoD. Unlike NMC or lead-acid, Dakota’s cells operate at 3.2V nominal per cell, with a flat discharge curve (90% energy delivered above 12.8V for 12V packs). This ensures consistent power for trolling motors or solar inverters. But how does this affect real-world use? For example, a 12V 100Ah Dakota battery can power a 50W fridge for 24 hours, dropping only 0.5V. Transitioning to durability, Dakota’s welded terminals and ABS cases withstand 50G shock loads—critical for ATV or marine vibration.
| LiFePO4 (Dakota) | NMC |
|---|---|
| 2000–5000 cycles | 800–1500 cycles |
| Thermal runaway at 500°F | Thermal runaway at 300°F |
| 3.2V/cell | 3.6V/cell |
What voltage and capacity options exist?
Dakota offers 12V, 24V, 36V systems with 10Ah–135Ah capacities. Their modular design supports parallel/series configurations up to 48V. Pro Tip: Use 24V setups for solar arrays—halve amperage, reducing wire costs.
Standard 12V models (e.g., DL+ 12V 100Ah) deliver 1280Wh, while 24V packs (DL+ 24V 100Ah) provide 2560Wh. For high-demand applications like electric winches, 36V 40Ah packs supply 1440Wh. Capacity tolerances are ±3%, ensuring precise energy budgeting. Transitionally, higher voltages reduce current draw—crucial for minimizing heat in long cable runs. What’s the trade-off? A 36V 40Ah Dakota battery weighs 27 lbs, whereas a lead-acid equivalent would be 48 lbs. Real-world example: A 24V 135Ah Dakota battery can power a 2000W inverter for 1.5 hours at 90% efficiency.
How does charging work for Dakota batteries?
Dakota Lithium uses 14.4V (12V) to 43.8V (36V) CC-CV charging, with 10A–25A built-in BMS. Full recharge takes 4–10 hours via compatible chargers. Pro Tip: Bulk charge at 0.5C (e.g., 50A for 100Ah) to minimize downtime.
Charging starts with constant current (CC) until reaching absorption voltage (14.4V for 12V), then shifts to constant voltage (CV). The BMS terminates at 100% SOC, preventing float-induced stress. But what if you use a lead-acid charger? Most Dakota batteries tolerate 14.6V absorption, but repeated overvoltage triggers BMS disconnect. For solar setups, MPPT controllers must align with Dakota’s voltage specs—mismatched controllers waste 15%–20% energy. Transitioning to practicality, a 12V 100Ah pack recharges in 5 hours via 20A charger versus 10+ hours for lead-acid.

FAQs
Yes, they operate from -20°F to 140°F, but charge only above 32°F. Built-in heaters in Pro models enable charging down to -4°F.
Are Dakota batteries compatible with solar systems?
Absolutely—use MPPT controllers set to LiFePO4 voltage (14.4V for 12V). Avoid PWM controllers, which lack precision for lithium chemistry.
