Our smart chip precisely locks the voltage to protect your expensive Lithium investment from overcharging. (Compatible with:Lithium LiFePO4, AGM, GEL, SLA, Lead-Acid).
- [VISUALIZED INTELLIGENCE - SEE THE POWER] Don't guess with blinky lights. Our upgraded Large LCD Screen displays real-time Charging Current (Amps), Voltage, Temperature, and Battery Percentage. You will see exactly how much power is pouring into your battery.
- [12V/24V AUTOMATIC DETECTION & REPAIR] Instantly identifies 12V or 24V systems upon connection. Features a pulse Repair Mode to help activate old, idle, or stratified batteries and restore lost performance. (Note: Cannot activate a totally dead battery with 0V).
- [FORCED CHARGING MODE]if the voltage of a 24V battery is too low and mistakenly recognized as a 12V battery, you can manually activate the forced charging mode (refer to the manual or contact customer service)

Haisito Battery Chargers H-20 Editorial Review
The Haisito 20-Amp Smart Battery Charger has garnered a mixed reception from customers, particularly for its effectiveness with lithium iron phosphate (LiFePO4) and lead-acid batteries. Users have praised the charger's automatic voltage detection and rejuvenation capabilities, which help restore older batteries to extend their lifespan. This feature has been particularly well-received, with many noting how this charger efficiently revives LiFePO4 batteries to their optimal voltage of 13.8 volts without requiring any manual intervention. The charging speed of up to 25 amps is noted by users as impressive, though many report that the maximum output tends to hover around 20 amps, aligning with the product designation and leaving some customers feeling misled by the advertised maximum of 25 amps. However, the overall charging performance is generally acknowledged to be effective, with several customers noting that their LiFePO4 batteries charged fully and efficiently within a reasonable timeframe. On the downside, the charger has its quirks. Users have remarked that the fan is Considerably loud, making it unsuitable for indoor use, and there have been concerns raised about a noticeable spark when plugging the charger into an outlet, which could indicate potential electrical issues. A few users have reported failures after multiple uses, leading to concerns about the long-term durability of the product. Overall, the Haisito 20-Amp Smart Battery Charger stands out for its smart features and charging capability, but potential buyers should be aware of the noise level and some durability concerns. **
