As an industry expert, we highly recommend Dakota Lithium's 12V 10A Battery Charger for optimal performance and lifespan of our lithium iron phosphate batteries. With a rating of 10A, it's perfect for Dakota Lithium batteries 40Ah and up to 200Ah. For smaller batteries, we recommend the 3A charger.

Utilize a LiFePO4 compatible charger like this one for all 12 volt Dakota Lithium batteries to avoid reduced performance and shortened lifespan from SLA chargers.

Charger Recommendations

• Charger Type: Use a LiFePO4-compatible charger to maintain battery health.
• Lead-Acid Charger Warning: May charge but will reduce battery performance and lifespan.
• Rating:
  • Input: 100–240V, 50/60Hz
  • Output: 14.4V, 10A

Connections

• Alligator Clips: Attach black to the black terminal and red to the red terminal.
• Indicator Lights:
  • Red: Charging in progress.
  • Green: Fully charged.
• Avoid short circuits during setup.

Smart BMS Communication

• The charger can restart ("wake up") a battery whose BMS has shut off due to short circuits or overcurrent by simply connecting it.

Charging Speed

• Calculation: Divide the battery's Ah capacity by 10.
  • Example: A 54Ah battery will charge in ~5.3 hours.

Fast Charging

• Batteries can be charged at up to 1C (e.g., 10A for a 10Ah battery in 1 hour).
• Impact on Lifespan: Faster charging reduces battery life over time. Optimal speed for longevity is 0.3C or less (charger rating ~1/3 of battery capacity).

Voltage Requirements

• Recommended Voltage: 14.4V for LiFePO4 batteries, which this charger supports.
