What a coincidence! I activated and charged my two LiTime 280ah batteries today with LT cutoff and BT that I received yesterday. The BT reported about 83 amps by the BMS. I am setting our 5W up with 1,440-w of solar and 580ah of LIFEPO4 as my wife is ops manager for about 75 USFS campgrounds over 5 area managers and our summer home base has no power run to it all. Sure glad you ran this test, I'll report how we like our 90-amp charger this summer as well. - Davey - KU9L
Hooked two LiTime100ah TM batteries up to my RV. They are working great! Definitely recommend these batteries, teo cost what one of most of the other brands cost. Now to see how long they last.
I recently purchased a Li-Time 50 amp Lipo4 battery with the Bluetooth option. Seems to work well. I do like the phone app to monitor what the battery is doing. Mostly using the battery for off grid radio operation.
Thank you for the review. Would be nice to see a clamp meter on the AC side to see what it pulls from the wall under those 1200'ish watt charging loads to the battery.
I can check but my I'd be surprised. My feeling is they are copper since they are soldered into the circuit board and barely heated up with 80 amps constant flow. Copper clad aluminum would be a pain to solder properly and crimp and the cost savings on a short relatively thin gauge cable wouldn't add up to much. Cheers, Ray
I've found my similar 40amp LiFePo4 charger uses about 2 watts when unplugged from AC if left connected to the battery. Can you see any watt leakage from the battery/charger when it's unplugged from AC? Great info you gave! Glad for the generator check.
We have the Li-Time 40Amp DC/DC charger. After the charge cycle is completed - 14.6V, the charger continues to apply a constant voltage of 14.6V This is what their charge graph implies. We confirmed with a DVM on the output. Not ideal in a mobile environment having that high of a voltage on the DC Bus. The specs on the charger show no float voltage after charging when LFP is selected.
What model of charger is that. Is it older? Maybe it was designed for manual operation to charge the Li until the BMS shuts down, then remove. This one I reviewed has 3 stages. Precharge, Constant Current and Constant Voltage. www.litime.com/cdn/shop/files/LiTime12V80ALiFePO4batterycharger_6.webp?v=1723688860 So it can remain hooked up. Cheers, Ray
If you're battery or battery bank cam handle the amperage. 160 amps. I often use multiple charging sources at the same time with my lithium batteries. They will lap up whatever I throw at them unless I go over the max charge amperage. In that case, the battery may shut down to protect the cells.
50% of a 300Ah battery is 150 amp hours so charging at 80 amps and if you calculate for wiring and BMS losses due to heat and the reduction of charge amps near the end of charge it will take approx 2 hours. With a 40 amp charger about double that 4 hours.
Li Time specs said it was designed for their batteries only. So I removed it from my consideration. I am happy to see you doing a real test. I currently have 2 100aph lithium bc batteries connected in parallel.
Likely a legal disclaimer since they can't anticipate what people will do and try and sue over or maybe to get people to buy their batteries. Personally, I wouldn't worry about hooking it up to any 12-volt LiFePO battery that has a BMS with max voltage and current protections. Many battery companies don't even make chargers but indicate their prefered charging specs. 14.6V is pretty standard as a max charging voltage.
That charger in your video should not be applying 13.8V to the LFP battery. It doesn't need float voltage. Have you measured the current after the charge cycle is complete? I would be curious. Hopefully there isn't any, otherwise, someone who leaves the charger connected will shorten the life of the internal cells.
You can see at this point in the video the charger was still on with green light. The battery BMS reports a voltage of 13.68 and 0 amps and 0 watts th-cam.com/video/bbJpVz7Z8iw/w-d-xo.html

Sounds like a great setup! Should have lots of power being that its during the summer with high sun and long days.
Thanks Ray! Gotta get one of those!
I just got one, it seems to work fine for me.
I got one of these a few days ago…no complaints so far. I would like to have spade terminals instead of the rings, though.

I saw a review comment on the Li Time website that said it was around 1300 watts on the input side when charging at 80 amps with fans running.
I'd scrape the heat shrink on the ring terminals to make sure the cable isn't aluminum.

I did a test this morning with my clamp on ammeter it showed no current flowing so 0 watts used when unplugged. Cheers, Ray
At 13:30 the 2 key pins should be bent straight that's awfully close to the other pins and hot snot to hold things down is so cheap

What clamp meter is that for DC.?
BTMETER BT7200APP th-cam.com/video/irhbS0QVs6M/w-d-xo.html Got it when we got the boat to test things like the alternator output amps.
Can you use 2 of them at the same time?

How long did it take to charge that 300 amh battery from 50 Percent and approx.how long would it take with the other 40 amp charger ?
50% of a 300Ah battery is 150 amp hours so charging at 80 amps and if you calculate for wiring and BMS losses due to heat and the reduction of charge amps near the end of charge it will take approx 2 hours. With a 40 amp charger about double that 4 hours.
My predator 2000 can power my xantrex freedom 2000 xc and charge my batteries at the full 80 amps
