Dakota Lithium optimized this 10A charger for 12V LiFePO4 batteries from 40Ah up to 200Ah. It delivers the correct charging profile to maximize performance, reduce downtime, and help extend battery life. For smaller batteries, use the 3A charger. Standard SLA chargers may work, but they can reduce battery performance and long-term lifespan.
Description
Dakota Lithium has optimized this charger for use with our lithium iron phosphate batteries (LiFePO4). Rated at 10A this is the perfect size for Dakota Lithium batteries over 40 Amp hours and up to 200Ah. For smaller batteries we recommend the 3A charger. All 12 volt 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.
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, 10.0 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?:
Charges at a rate of 10 amps. To determine your charging speed take the amp hour rating of your battery and divide by 10. For example, a 54 amp hour battery (Ah) would charge in 5.3 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.
