Set name: 100Ah RV & Trolling Motor(Group 31)
I had it for two and half years used it every week sometimes multiple days. Used for a 45lb trolling motor. Used in fishing tournament with 8 hours on the water where I was judge, so I was constantly moving and it lasted the 8 hours plus 4 more the next day. Charged during the break and lasted the entire tournament. Very impressive battery life. Unfortunately the price has doubled since I bought it otherwise I’d buy another one. Performance was amazing. Just sold it with my boat. It’s 1/4 the weight of an acid battery. Plug and play

Arrived early and perfectly charged (54%) for a Lithium battery. Fit into existing Group 27/31 box on the trailer tongue. Fully charged in about 2 hours on shore power, haven’t tried charging with solar panels yet. Very happy with the product, app and installation was effortless!!

These batteries are being used to replace the LA batteries in our Travel Trailer. Installed along with a new Converter charger from WFCO. Batteries came at 50% charged. Batteries needed to be discharged before Converter would recognize as lithium. App is very straight forward and showing it will take a little over 8 hours to fully charge starting at 7%. The size fits perfect in the same space and the weight is over 50% lighter then the LA batteries. I'm very satisfied with my choice.

Had a few issues when I first connected batteries in parallel after a full separate charge on both batteries. Tech support was very helpful and had me reconnect several times to wake it up out of sleep mode. First trip out in motorhome batteries ran levelers and slides well and kept the fridge running cold. Batteries quickly recharged from alternator and Li-bim225. Continued charging once on shore power.

Update 2: So it appears that the first battery that was returned was shipped fully charged and had settled to a resting voltage of 12.8. This is why it would not charge. I believe now the battery would have been fine if I had discharged it some. I was under the impression that these batteries are shipped not charged fully. Also the battery label now match the newer branding when ordering from Amazon. Old review: I ordered this battery and connected it to a known good working MTTP solar controller. The controller was setup to charge Lifepo4 and the settings matched Li Time settings from the user manual. It would connect for a second and then instantly disconnect charging. Connected to a small 1.5amp charger I have and it indicates that the battery is full(see picture). Now waiting to see how much this return is going to cost me. I also reordered a replacement battery of the same make / model. Hoping it wasn’t a mistake. Side note: In the meantime I had ordered a second battery from the Li Time e-bæy store and it arrived and works fine. The e-bæy battery has different markings for negative and positive stamped in the top mold of the battery. It also as branding of LTCP. Wonder if the batteries on Amazon are old stock? Update: Li Time sent a pre paid label to send the battery back.

I was a little leary about these as they are so much cheaper than the name brand lithium ion battery's that I priced from Interstate, bass pro, etc. However, I have been impressed with how well they hold up and how long the charge lasts. We have yet to have one die or run out of power. Ive purchased 2 for our boat and we use it with a 55 lb minn kota. Motor runs well on full speed with no issues from the battery. Also using it for fish finder and when we are trolling at low speed along the lake shore while fishing. I would buy another one.
