Talk about beefy. This is replacing my 7amp charger which is small in comparison. This is 5 times larger but I’m glad it’ll charge my battery in 3 hours. Haven’t used it yet but I’d it does what’ what it’s supposed to do I’ll be very happy.

Some of the best customer service even before it arrived with several messages to ensure your happy right from the start! My 12V 200AH LiFePO4 Battery charged from empty to 100% in a little over 5 hours & the charger stopped charging once finished just as advertised. So far I'm really happy & give it my recommendation.

Intelligent Power Queen charger does the trick. It can sense battery condition and selectively apply the voltage and current necessary to safely charge the battery. Just like old school chargers, when a battery is very dead. The more current and voltage it will draw in taking a charge. If your battery is just a little down, it will not require the maximum to charge the battery. The cables get a little warm, but nothing excessive.I highly recommend the charger for these batteries. I own one and the batteries and am very pleased with them.

Charged my 200 amp lithium just fine. The cables to the battery are smaller than I’d expect but still worked well and never really got hot.

I have only used it to charge my new 300 amp hour battery and it was pumping 38 amps for 5 hours, the wires did heat up but the charger kept cool ( it is fan cooled): The charger output and battery input wires are going to require monitoring. Overall it did charge the battery and the display seemed accurate. I am using this in my rv and am reluctant to upgrade my converter over wire size issues.

It's easy to use with no settings. The display let's you see how the charging is going. The 12V wires heat up a bit more than I expected, Power Queen should have used a larger gauge wire or made it possible to use your own cable.

This charger is superb! I use it to charge a bank of 12 marine deep cycle batteries with my small (luggable) Honda generator when lack of sun on my photovoltaic panels (10} depletes the battery charge.
