I was concerned since I have never bought this product before and was concerned about safety with the LiFe04 batteries.First, the product was made well and was as described with the dimensions and ratings, not always the case with online shopping. This was for a Ham radio field renewable power source and the dimensions would be critical.I was pleasantly surprised by the attention to detail on the operation and safety material. It made me feel better about the product. There was also a lot information about thier support and replacement should there be an issue.Very pleased.I have been using this goes several weeks and the product works very well. Charges and powers my ham radios great. All positive.

These batteries work fine, but if you're looking for an upgrade or replacement to your old Black and Decker CM1936 lawnmower, these aren't it: they're just slightly larger where you need to file down the side of the plastic panels inside the battery housing to make them all fit. You'll probably also need a dedicated 36V lithium battery charger wired up with Anderson powerpole connectors instead of the stock charger which is just a simple lead-acid battery charger

I bought 4 of the 12.8 volt 20 amp hour batteries hooked them up in parallel and in series to run 24 volts 1 kw worth of battery. Made this into a home made solar generator for remote hook up for field running my ham radio’s. I do realize its more power then most would need however this way it can charge my HT’s and keep a whole bunch of radios functional. The batteries made the system. the size and weight make this a great little field system. I would definitely buy these batteries again and will most likely change these out for some bigger batteries. I’m thinking 4 KW system next!

i did 2 capacity tests and was able to draw 5.8AH/72WH. Not quite 6AH/76.8WH it said on the label. I assume some of that is the BMS. I was able to charge it at 10A although in my application it will be charged much slower.Time will tell how long it lasts and if it holds a charge over time

Great value. I use on a kayak for a 9” Garmin 93sv uhd2 fish finder. It is plenty enough battery for an all day excursion. I haven't had any issues with it. Small enough to fit in the center hatch of an old town 120 pdl kayak. I typically use it twice for about 5 hours each before charging.

Very nice battery and packaged extremely well.

I ordered two of these batteries and really liked them so I ordered six more. I was sold on the three year warranty. With a three year warranty I decided they were worth trying out. A couple of months later I have three of the batteries that will not take a charge, a few weeks later I have six that are no good. These guys have gave me the run around, back and fourth, telling me I have the wrong charger, Along with other reasons they give me other than the fact that their batteries are bad, under warranty and should be replaced. I have other lithium batteries from other manufacturers that I have no problem with. I have three different chargers and try them all with the same result. These people do not stand behind their product.

So far so good on my kids 4 x 4 power wheel.time will tell but I try to keep it at 80% at all times. Last about twice as long as the AGM battery before it.
