This 12V lithium battery charger from Dakota Lithium charges at a rate of 3 amps and has been optimized for use with all lithium iron phosphate batteries (LiFePO4). This 3A charger is ideal for batteries with a capacity of less than 25 amp hours (Ah).
Input: 100-240 volts, 50/60HZ
Output: 14.4 volts, 3.0 amps
Alligator clips for ease of use. 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?
To determine your charging speed, take the amp hour rating of your battery and divide by the amp rating of your charger. For example, this 3A charger would fully charge a 7Ah battery 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 (or a rate of 1C). For example, you could use a 10 amp charger with a 10Ah battery for a 1 hour charge time. Charging at a 1 hour rate does reduce the battery 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 so we recommend that the charger amp rating is 1/3 or less of the battery amp hour rating for longest life.
What Voltage Should LiFePO4 Batteries Be Charged At?
14.4 volts is recommended for Dakota Lithium batteries. This charger charges at the optimal 14.4 volts.
What Is The Difference Between a 3 Amp & 10 Amp Charger?
The amp rating is how much energy goes into your battery in 1 hr. For example, a 10A charger will charge a 54Ah battery in 5.4 hours. An appropriate sized charger should be 1/3 or less (.3C) of the Ah rating of your battery.
