Ultra Fast 24v 20 Amp Dakota Lithium LiFePO4 Battery Charger

This firehose of power is optimized to charge large 24V batteries FAST while ensuring a long battery lifespan. Designed for use by our bass fishing pro staff who need to charge quickly between tournaments, this 20 amp (20A) charger will charge a 24V 50Ah battery in <2.5 hours, and a 100Ah battery bank in <5 hours. 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. Built in a high tensile aluminum case for rapid cooling, this charger is rated at 20 amps and is an upgrade for those of you who need to charge fast and play hard. All Dakota Lithium batteries should be charged using a LiFePO4 compatible charger like this one. SLA chargers will reduce the performance of the battery.

<p>Included Anderson plug with ring terminals for safe & easy charging. Simply plug the charger into the Anderson plug, and remove when done. Also compatible with all Connect-Ease trolling motor wiring kits (add on).

For 24 volt lithium batteries

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.

Charger rating

INPUT 100-240 volts, 50/60HZ. OUTPUT: 28.8 volts, 20.0 amps

Terminal Connections

Anderson SB 50 connections make it easy to connect your charger to the battery. Install the ring terminals using the bolts on your terminals. Bolt black to your black terminal. Red to your red terminal. Do not short circuit. Then connect the charger via the Anderson plug when you need to charge. 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 20 amps. To determine your charging speed take the amp hour rating of your battery and divide by 18. For example, a 36v 63 amp hour battery (Ah) would charge in 3.5 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 8 amp charger with a 8 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?

28.8 volts is recommended for 24V Dakota Lithium (LiFePO4) batteries. This charger charges at 28.8 volts.
