I bought a LiTime lithium battery for the travel trailer and found that the battery tender I have wil lonly charge a lithium battery to about 80%. A 4-stage charger is needed.This one seemed to meet the requirements and it does.I connected it to the battery the day before I was to install it, watched the LEDs blink and in the morning I had four solid green lights.When I installed the battery and connected the Renogy charge controller (from a solar cell) it showed the battery at 99%. Good stuff.

Works as advertised. Fully charged my lithium battery. Some mentioned that the charger seemed to get overly warm when charging. I have not experienced that issue.

I have another charger (NOCO) that works for a variety of automotive batteries including lithium batteries. The lithium iron phosphate battery that I bought is spec'd for 3.5 amp charging current. The other charger I had is current-limited to 2 amps, and it was just taking too long to charge the battery (BOTKU 30 amp-hr battery, also a great battery BTW). So, hoping to shorten the time need to charge the battery, I bought this UltraPower charger. It works exactly as expected, charging at the proper voltage, and even though it still took several hours to charge the battery, the time was reduced by roughly half compared to the other 2 amp charger. I didn't try to measure the charging current, which would have been interesting, but the battery never got warm in the least and I suspect that charging current was never above the spec'd 3.5 amp (spec'd for the battery). If it was ever greater than this, it is very unlikely to have done the battery any harm given that it never got the least bit warm and given that the battery voltage when I put it on the charger is just slightly below 12 V, 11.8 V to be precise. (Evidently, one of the main drawbacks of lithium iron phosphate is that they have to be charged slowly. Rapid charging that would cause the battery to get hot is not allowed.)Bottom line, if you are looking for a charger for this type of battery, and the spec'd charging current is in the range roughly 2 amp to 4 amp, my recommendation is that I have not found any reason to be hesitant to buy and use this charger. From my experience it is perfect for this class of battery so long as the spec'd charging current for the battery is in this range. (The charging current depends on the number of cells connected in parallel and is thus directly tied to the amp-hr rating of the battery.)
