WEIZE 24V 100AH Bluetooth LiFePO4 Lithium Battery, Grade A Cells, 150A BMS, Low-Temp Protection Deep Cycle 500A/3S Peak Discharge Battery for Trolling Motor, Solar System, RV, Camping, Off Grid

So far so good, I was using AGM batteries 130 AH and was going through the full charge in about 3 and half hours on my trolling motor 80 lbs thrust. I use anchor lock a lot, which uses GPS to hold the boat in one position no matter the direction of wind or the current is moving. The motor will hold position by speeding up and down and turn the boat accordingly.I got a great tip from a professional charter fisherman to switch over to lithium battery so I did my research and found that this battery was the best bang for the buck and had a great ratings. I don’t know why I waited so long, I can run 4 to 5 hours (same use) for 3 to 4 days before I have to charge the battery. You get Bluetooth reporting directly to your phone on the app provided by the manufacturer, I get all the rundown on the condition of my battery.

Great products. Customer service helped me out with a free replacement. Bought 2 12v batteries for my trolling motor. 1 the bms kept shutting off the battery. I'd have to jump start it to get power back. Sometimes once a trip, Sometimes 4 or 5. I contacted CS and they directed me to a couple test to do. After a few back and forth they sent me a brand new replacement. Ive had these batteries since March 2023. Bought an electric jack for my camper hitch. Works great! Definitely will get a battery for my camper next. Good company that backs it's products. I don't know why other had problems with CS.

I purchased two of these to power an outdoor vehicle. These have turned out to be a much better purchase than anticipated! The weight of these batteries are heavier than comparable batteries and in my case, that is a good thing. The longevity of the battery once charged is great. I can run the vehicle they are in all day for all days over a long weekend and almost not have to charge them. Once I do put the battery on a sufficient charger, it will charge overnight to full. I would definately recommend this battery.

Should have ditched the lead acid sooner. this thing is like half the weight and last 2x as long a similar 100ah lead acid.love it.

Do not buy this battery from this company. I purchased one roughly 6 months ago and have only used it a handful of times for my trolling motor and it is beginning to swell.I am past my return window with Amazon so I went ti the manufacturer. They said because I purchased from Amazon I need to reach out to them for support, but Amazon directs me to the manufacturer.That was the last email I received. I have emailed back 3 times since then asking about the manufacturer warranty with zero response.These are supposed to last years, and now mine is unusable and unsafe after less than one year and Weize will not even respond to me. I would have been better off getting a standard battery locally and instead I paid over double the price for something that only lasted a handful of times

****Update February 10 2025****I opened a ticket with Weize customer support. They responded within 24 hours and were very consistent with always replying within 1 business day throughout the process. They had me perform a number of tests, take pictures, provide additional details of the situation, provide details and documentation of the charge controllers I had tried to use.I will admit I got annoyed at how much they had me go through. However, I was outside of the warranty period so they had no obligation to help me at all. I appreciate that they worked with me when they weren't required to.My replacement unit arrived today and I tested the voltage before I even removed it from the box (which I should have done last time). It tested good and I have it hooked up to my solar installation now.I haven't had my replacement for long enough to do a full product review, but I can definitely say that Weize customer support is good. A separate customer support person even reached out to me after seeing my Amazon review to make sure I had a support ticket open.***Original review January 24 2025***I have been wanting to upgrade my solar storage from lead acid to Lithium for a while and picked this up during a sale. I knew my charge controller couldn't handle LifePo4, so I set this aside after unboxing until I could find a good deal on a new charge controller.I finally got a good deal on a Victron and started upgrading my system. That's when I stuck a Multimeter on the battery and realized it was only reading 7-8 volts. Up to this point, this battery was unused and still had the plastic caps on it, I even had to hunt down the terminal bolts as they had been "cleaned up" at some point in the previous 11 months.I figured those readings meant the battery was toast, but decided to connect it to the new charge controller (set for LifePo4 charging) and see if it would recover. After 4 days it is still only at 8 volts.Just to be sure I swapped in a 20AH 12v LifePo4 battery out of my portable power kit and it charges without issue on the new Victron.Being a LifePo4, this battery shouldn't have had any issues with sitting indoors for 11 months before being put on a charger. I'm disappointed.

Great battery and customer service. Would buy again.

20 months worth of use and still going strong. Sometimes run the batteries hard all day trolling motor and still have plenty of power at the end of the day.
