Feature:1. BATTERY PROTECTION: The battery equalizer has smart voltage compensation system that keeps the battery idle and automatically turns off when the voltage is low.2. AUTOMATIC BALANCE: The battery equalizer can be connected in series with the battery for a long time to maintain the charge discharge balance between series batteries.3. MULTIPLE PROTECTION: Can maintain balance in both charging and discharging direction, with reverse polarity protection, low voltage insulation, reverse connection protection.4. APPLICABLE BATTERY: This battery balancer is suitable for lithium batteries, nickel hydrogen batteries, lithium iron phosphate batteries, etc., effectively balancing voltage.5. WIDE APPLICATIONS: This battery voltage equalizer can be used for battery configurations such as cars, ships, motorcycles, solar panels, etc., compact and practical.Specification:Item Type: Battery EqualizerMaterial: ABS, PCBBattery Standard Voltage: 2x12VCompensation Current: 0-5AStandby Current: <3mAProtection: Reverse Polarity ProtectionUndervoltage Standard Value: 10V.Package List:1 x Battery Equalizer1 x User ManualNote:In the 24V or 48V battery pack, there will usually be an undercharge and another overcharge, over a long time, the overcharged battery gasification, the undercharged battery vulcanization, the battery life will be seriously affected, and the battery will be scrapped in advance.
