Can Progressive Dynamics PD4060K Be Used to Continuously Charge Lithium Batteries
Question:
I am lead to believe that the PD4060K should not be connected to lithium batteries constantly. I understand the charge function is continuous and does not taper the charge like other charging systems. Have you found that to be the case? Thanks

As long as your Progressive Dynamics Mighty Mini AC/DC Panel and Converter/Smart Charger - 60 Amp # PD4060K is the newer version made in 2020 with that lithium battery switch (see attached) then the batteries can be connected constantly. That switch is meant to communicate with the Mighty Mini and tell it what type of batteries are being used in the battery bank so the charger knows how to interact with the battery bank for the best charging profile.
There are some different charging modes which we go over on the product page and I'll list them below. The charging modes can vary but under the "Normal" setting the voltage going to the battery bank will drop once the bank beings to reach capacity:
1. Boost: This mode charges at the full rated load for a quicker recharge time. This is where most of the charging happens. It charges the battery up to 90% of the full capacity.
2. Normal: This mode provides controlled voltage to ensure a full charge. Once the battery begins to reach capacity, the normal state will kick in and reduce the voltage to safely complete the charge.
3. Storage: Once the battery reaches full charge and remains unused for 30 hours, this mode maintains a lower voltage to compensate for self-discharge. This reduces battery stress and minimizes gassing and water loss.
4. Equalization: This mode activates to prevent stratification and sulfate buildup during extended storage cycles. These two issues can damage a battery by causing the accumulation of acid at the bottom of the battery and hardened sulfate crystals on the battery plates. This mode is especially helpful when your battery is going unused during storage.
