Frequently Asked Questions

Which battery types are compatible with this charger?

This charger is designed for 84V Lead-acid batteries, including SLA, GEL, and AGM types. We also offer versions specifically for Lithium (LiFePO4, Li-ion) batteries.

What do MF, GEL, and AGM stand for?

These are abbreviations for different lead-acid battery technologies: Gel, AGM (Absorbent Glass Mat), and MF (Maintenance-Free).

Can I charge multiple batteries in parallel?

Yes, the charger can handle batteries connected in parallel as long as the total capacity is within the recommended range. Ensure high-quality wiring is used to handle current between batteries.

Is it safe to leave the charger connected after charging is complete?

For lead-acid batteries, the charger enters a maintenance (floating) mode with a small current. While it is designed for this, we recommend not exceeding 24 hours of connection after full charge. For lithium batteries without a BMS, do not leave the charger unattended.

What safety protections are included?

The charger features integrated protection against short circuits, over-voltage, over-temperature, and reverse polarity to ensure maximum safety for your battery.
