20-Amp Lifepo4 Lithium AGM Gel Smart Battery Charger, 12V/20A 24V/10A Trickle Charger, Maintainer for car Boat Motorcycle, Lawn Mower

This battery charger works. We had a battery on a SxS that was having trouble staying charged and would have to be jump started. We plugged it into this charger and ran the repair cycle and the battery has stayed charged ever since. We bought it to charge a LiFEpo4 battery, but couldn't get it to kick the battery on. We finally decided the battery was bad.

Great little charger it charged my 12V lithium battery for my RV in about five hours and I haven’t had to recharge since

Esto está súper bueno duradero y buen precio lo volvería comprar

Works good. Fan is loud.

Very easy to use.

I bought two of these and both were returned for the same problems! It charged a LiPO4 100AH battery fine (and turned off the terribly noisy fan upon completion) but then when the battery was discharged to 60% charged, it still falsely reported a FULL charge even though the voltage was now only a little over 12 volts instead of 13.97 volts. It’s a dumb charger that can’t measure a discharged battery after charging and incorrectly reports it as fully charged. The charger never restarted to charge a discharged battery. The battery was fully discharged and the charger still showed that it was at full charged and just sat there until I removed and reconnected the AC cord to restart it. Then it powered with the wrong type of battery selected and had to be manually reprogrammed to the lithium battery setting. This is dangerous and a really dumb “smart charger”!!The next problem is that both chargers radiated VERY strong RF noise all across the radio spectrum. One can’t use a charger that blocks reception of all HF signals with extremely strong interference. Simple and effective noise filtering / shielding could have eliminated this problem, but it’s just plain dumb to market strong noise radiators! The F.C.C. has restrictions on such unintentional radiators of strong noise for a reason and this defect was not disclosed in their technical specs.The last issue is that the fans are extremely LOUD and could be heard quite clearly next door. This might be okay in a garage setting but such loud noise levels should have been disclosed in the specs. To fail such a disclosure is just plain dumb!

Nice little charger and seems to charge fairly fast

this is very versatile, the quality is very good, it is everything that I was hoping for. the price is reasonable.
