Built to trickle charge large 24 volt batteries, this lithium / LFP / LiFePO4 / Li-ion charger will charge any lithium battery at a rate of 5 amps an hour. Dakota Lithium has optimized this charger for use with our lithium iron phosphate batteries (LiFePO4 or LFP). Not recommended for charging lead acid or SLA batteries, it is too powerful. This charger is rated at 5 amps and will charge a 24V 10Ah Dakota Lithium battery in <2 hours, or a 24V Dakota Lithium 50 Ah battery in <10 hours. This charger will work with any Dakota Lithium battery wired in series to make a 24V LiFePO4 lithium battery. All 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.
SPECIFICATIONS
We highly recommend you use a LiFePO4 compatible charger. 24V chargers for lead acid batteries may work, but will decrease performance and lifespan of the battery.
INPUT 100-240 volts, 50/60HZ. OUTPUT: 28.8 volts, 5.2 amps
Alligator clips make it easy to connect your charger to the battery. 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.
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.
Charges at a rate of 5 amps. To determine your charging speed take the amp hour rating of your battery and divide by 5. For example, a 24v 10 amp hour battery (Ah) would charge in 2 hours.
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 5 amp charger with a 5 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).
28.8 volts is recommended for 24V Dakota Lithium (LiFePO4) batteries. This charger charges at 28.8 volts.
This charger is included for free with your purchase of a 24v 50Ah battery from Dakota Lithium.
