Haisito delivers a massive 20-Amp continuous current (for 12V) and 10-Amp (for 24V), charging your dead battery up to 200% faster than standard 8A/10A chargers. Essential emergency gear for large SUVs, Pickups, and Farm Tractors facing cold winter starts.
- [SAFE & DEDICATED Lithium&LiFePO4 ALGORITHM] Unlike generic chargers that claim compatibility but risk damaging your BMS, Haisito features 3 Independent Lithium LiFePO4 Lead-Acid(PB) Mode. 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)

If you are looking for a charger for a life po 4 for battery , look no further. We bought this on a recommendation from our neighbor after buying two other chargers , locally. Favorite , very great , and we're able to charge our dead battery within three hours way faster than the ones we purchase locally.

Excellent products charge the batteries very well. It's small so it's comfortable to take everywhere. It helps you indicate if the battery is in good condition or not.

Pros: It's a cool little charger. It's tiny so it's portable and it gets the job done. The read out for the charge status and sutomatic shutoff are cool. The display looks good in general. The price is competitive too. The fans aren't too loud so I didn't find it annoying. Cons: Not having a trickle charge mode seems like an oversight for something like this. It would be nice to be able to carry it with my motorcycle and having a trickle charge would make it way more useful. It's built a little cheap and I am worried it's going to break. It feels a little sketchy to set it and walk away from it but so far I haven't had any issues. The connector for the leads is on the smaller side and doesn't feel robust. The clamps in particular dont have wide jaws and feel cheap.

Lots of options for whatever battery type you are charging and the cost was reasonable.
