⚠️ Always connect the battery first before turning on the power, and disconnect the battery after turning off the power to prevent sparking.

Frequently Asked Questions
Q: Can this charger charge a 72V lithium battery?
A: Yes. The output voltage range is 9.6–88.2V, so it comfortably covers 72V lithium battery packs (which typically require around 84V at full charge).

Q: Is this charger suitable for lead-acid batteries?
A: Absolutely. The CC/CV mode works perfectly for lead-acid batteries, and the adjustable current allows you to follow manufacturer-recommended charging rates.

Q: What is the maximum current I can set?
A: You can adjust current from 2A to 20A continuously. For most batteries, we recommend starting at a lower current (e.g., 0.1C of battery capacity) and increasing as needed.

Q: Does this come with cables and clips?
A: Yes, the charger features reverse polarity protection to prevent damage if you accidentally connect the leads backwards.
