PowMr Battery Equalizer Voltage Balancer for 24V and 48V Battery Banks
PowMr Battery Equalizer Voltage Balancer for 24V and 48V Battery Banks
The PowMr Battery Equalizer is an energy transfer device that monitors and balances voltage differences between batteries in series, effectively extending the lifespan of your battery bank. It automatically initiates energy transfer when it detects a voltage gap of 10mV, allowing it to maintain consistency across lead-acid, LiFePO4, NiCd, and NiMH battery packs.
Key features
- Automatic Voltage Balancing – Transfers energy from high-voltage batteries to low-voltage ones once a 10mV difference is reached to maintain pack equilibrium.
- 24/7 Continuous Operation – Designed to function around the clock, providing balance during static, charging, and discharging conditions.
- Broad Battery Compatibility – Supports multiple chemistries including lead-acid, lithium iron phosphate (LiFePO4), NiCd, and NiMH.
- Flexible Configuration – Each unit handles up to 4 batteries; fewer batteries can be used by leaving unused cables suspended.
- Reverse Polarity Protection – Built-in safety measures protect the system against incorrect wiring connections.

FAQ
Does it fit my battery type?
This equalizer is compatible with lead-acid, lithium iron phosphate (LiFePO4), nickel cadmium (NiCd), and nickel hydrogen (NiMH) batteries.
How does it balance the batteries?
When the voltage difference between two batteries reaches 10mV, the device automatically transfers electrical energy from the high-voltage battery to the low-voltage battery.
Can I use it with fewer than 4 batteries?
Yes, a single unit supports up to 4 batteries; if you connect fewer, the remaining cables can be left suspended without affecting performance.
Does it work when the battery is charging?
Yes, the device supports 24-hour continuous operation, balancing the battery pack during static, charging, and discharging phases.
