LiTime 80 Amp Lithium Charger – Big Power & Fast Charging
The cost of Lithium batteries had decreased significantly over the past 12 months. This is great news for the RV traveler who needs more 12V power during those times when campground power isn’t available. This is also beneficial for those who live off-grid and battery power is important for their disaster recovery plans. With these lower prices we’re now able to purchase larger capacity lithium batteries without blowing the budget. BUT! Charging these batteries can be an issue if placed in an older RV where the charger-converter doesn’t support a lithium charging profile. Or more so, for the off-grid power needs if the sun doesn’t shine for several days and the batteries are running low. For those large amperage lithium batteries, that’s where a LiTime 80 Amp Lithium Battery Charger comes to the rescue. This 120V AC powered high amperage lithium battery charger can be the perfect solution bring those 300Ah and larger batteries back to a full charge and fast.
Why A High Amperage Battery Charger Is Important
When charging a 300Ah battery and larger capacity batteries, time can be critical especially during periods where there’s limited sun. If the battery is part of an off-grid solution and solar charging is reduced, the only option is a generator and an AC powered charger. Using a low amperage charge, may fit the budget short term, but the savings will be quickly offset with the cost of full running a generator for long periods to charge the battery. That’s were a unit such as a LiTime 80 Amp Lithium Battery Charger can be beneficial, quickly charging a large lithium battery installations all while saving costly generator fuel.
LiTime 80 Amp Lithium Battery Charger
When charging a Lithium battery a number of key factors should be followed to protect the battery and ensure its longevity. The LiTime 80 Amp Lithium Battery Charger is designed for 12V LiFePO4 batteries with a 3-stage charging mode (Pre-charge, CC, CV) and 4 safety protections during charging including:
- Over temperature protection,
- Output short-circuit protection,
- Reverse polarity connection protection, and
- Output over-voltage protection.
The charger has LED display indicators to show battery charging status and an ON/OFF switch making it easy to operate. During our use, we found the charger aluminum alloy shell provided good heat dissipation throughout a battery’s charging duration.
This charger can activate an idle or weak battery and restore it to its normal voltage if battery’s BMS protection is triggered and the battery voltage is too low.
Testing The LiTime 80 Amp Lithium Battery Charger
We had a LiTime 300Ah battery from a previous evaluation and completely discharged the battery until it’s BMS shut the battery off. This was done to test the battery charger’s ability to charge a battery where the BMS protection is triggered or the battery voltage is too low. When we connected the charger and powered up, the battery BMS woke up and the charging process started with no issues.
In out test, we found the battery charger consistently provide 77 to 78 amps of charging power with a high efficiency only using 14A of 120V AC power. The charger restored the battery in approximately 3 hours. During the test, we checked the temperature of charger case, top of the battery, and the charging cables. Battery and charger case were slightly warm and of no concern. There charging cables were warm to touch and our laser thermometer registered cable temperatures at 103 to 104 degrees throughout the test. Of little concern due to the fact of time to charge and the high amperage from the charger. Per specifications, once the battery was fully charged, the charger went into idle mode.
We have been using the charger on large capacity batteries over the past several weeks and along with these tests, found the charger to operate well charging the larger capacity batteries quickly. See the video below to see the details of our test and results. As discussed in the video, I have have provided the voltages for lithium battery capacity.
One note, not all lithium batteries can support an 80 amp charger, this is especially true for most 100 and 200 amp batteries. For these needs, we use a LiTime 20 Amp Lithium Battery Charger. LiTime also has 40 and 60 Amp chargers available. It’s important that you review the specifications of your battery and use an appropriate sized battery charger.
Our thanks to LiTime providing the charger for our review. We have provided links below the video if you are needing more information about LiTime’s lithium batteries and chargers.
