Paid like $30 for a 5 amp charger. Good find. Just make sure to match your battery to the charger. Wouldn't use this on anything less than a 50ah battery.

Edit: see it has adjustable output. So will work for even 10ah batteries. Nice. In for one.

Do you know if the actual charging voltage is adjustable or only the type of battery? If not, I need to see the charging profile for each setting. I am looking for a charger of a Tesla NMC battery but need to limit the max voltage to 24.5V.

Seriously doubt the voltage is adjustable at this price, likely only the current. Probably has a 12v lfp and 24v lfp bulk/absorb/float curve and that's it. And even more doubtful is that it supports NMC. Description says agm, gel, lead acid and lfp only.

no, i think too many amps and volts too possibly. maybe try this, i like the idea of it having low amps to prevent potential issues https://www.harborfreight.com/05-...59000.html maybe this one fancier, slightly higher amperage, ever so slightly lower reviews https://www.harborfreight.com/aut...62813.html

Good charger, when it works. I received a faulty unit and support sent out a replacement after a few emails and submitting sufficient evidence. Would definitely recommend.

*I also bought 2x 12.8V 150Ah from eco-worthy this summer.

I bought 2x 12.8V 150Ah from eco-worthy this summer as well. I have had a collection of eco-worthy batteries over the past five years, all have worked well for me. I do wish the earlier ones had Bluetooth capabilities, though.

Looking for something to maintain lawn tractor or motorcycle battery over the winter. Will this work?
