This 3A LiFePO4 charger is built for smaller 12V Dakota Lithium batteries under 25Ah, including models from 7Ah to 25Ah. It delivers the proper charging profile to help protect battery health, maximize performance, and extend lifespan. For best results, all 12V Dakota Lithium batteries should be charged with a LiFePO4-compatible charger.
Description
Dakota Lithium has optimized this charger for use with our lithium iron phosphate batteries (LiFePO4). All 12V Dakota Lithium batteries should be charged using a LiFePO4 compatible charger like this one. SLA chargers will reduce the performance and lifespan of the battery. This charger charges at a speed of 3A an hour and is optimal for batteries < 25Ah. For batteries greater than 25Ah like the 54Ah or 100Ah battery we recommend the 10 amp charger available here.
Technical Specifications
-
For 12 volt lithium batteries:
We highly reccomend you use a LiFePO4 compatible charger. 12v chargers for lead acid batteries may work, but will decrease performance and lifespan of the battery.
-
Charger rating:
INPUT 100-240 volts, 50/60HZ. OUTPUT: 14.4 volts, 3.0 amps
-
Terminal Connections:
Alligator clips for ease of use. Clip black to your black terminal. Red to your red terminal. Do not short circuit. Red light on the charger will turn on when charging. Light turns green when the battery is full.
-
Smart BMS Communication:
Charger will restart or "wake up" a Dakota Lithium BMS that has turned off a battery due to short circuit or excessive amp draw. Simply connect the charger to the battery to initiate a restart.
-
How fast will my battery charge?:
Choose a 3 amps. To determine your charging speed take the amp hour rating of your battery and divide by the amp rating of your charger. For example, a 3 amp charger would fully charge a 7 amp hour battery (Ah) in 2.3 hours.
-
Can I charge my battery faster?:
For most applications a charging time of 3 - 10 hours provides the longest lifespan for your battery. But if you have an application where you need rapid charging Dakota Lithium batteries can be safely charged in up to 1 hour (at a rate of 1C). For example, you could use a 10 amp charger with a 10 Ah battery for a 1 hour charge time. Charging at a 1 hour rate does reduce the lifespan over time. In our laboratory testing we found that the longest lifespan for Dakota Lithium batteries was at a charging speed of 0.3C or less (we recommend that the charger amp rating is 1/3 or less of the battery amp hour rating for longest lifespan).
-
What voltage should LiFePO4 batteries be charged at?:
14.4 volts is recommended for Dakota Lithium (LiFePO4) batteries. This charger charges at 14.4 volts.
-
What is the difference between a 3 amp and 10 amp charger?:
The amp rating is how much energy goes into your battery in 1 hr. For example, a 10 amp charger will charge a 54 amp hour battery in 5.4 hours. An appropriate sized charger should be 1/3 of less the amp rating of your battery. For example, a 3 amp charger is perfect for a 10 amp hour (Ah) battery.
