Review: Won't deliver 40A as claimed - The charger is good. But it does not deliver 40A as claimed! I have used it for a month now, and the best i got was 25A max. Sometimes it cannot deliver more than 10A even, depending on the temperature. It is installed in a ventilated location. It's charging a 100 AH Lifepo4 battery, and I run a fridge in my Jeep. I struggle to keep the battery charged.
Review: Muito bom mesmo

### ⭐⭐⭐⭐⭐ Review
*by C***S on 21 September 2025*

I have to say I was skeptical at first reading some of the reviews but this DC to DC charge controller works amazingly well. I got the 25 amp model and it provides 24.9 to 25 A without any issue. It charges the lithium iron phosphate battery, far quicker than just having a direct connection with a relay to my start battery, the relay would engage when the alternator started putting out power but I noticed I was only charging in about 17 A MAX because the voltage was not quite high enough as the vehicle battery was a lead acid battery and that charged around 13.8V…but the lithium ion battery would like to see 14.6 so this actually has a boost converter in it that will raise the voltage from the 13.8 available in the car to about 14.8 V to charge the lithium, iron phosphate battery, it appears to have a smart regulating technology in it , so it does not give too much voltage to the battery but enough for it to charge quickly. Overall, it’s very well-built, easy to use. Has a nice heat sink that does not require the use of a fan to keep it cool, this is a nice feature, so I don’t have to listen to any noisy fans as it was very quiet and it appears to , keep my lithium battery very happy
