I bought this to use for my Livescope while fishing. Wanted a light enough battery to be portable but still have enough capacity to last a day of fishing.I have LVS 32 with Garmin SV93 graph. So far it has made it on all 3 fishing trips without dying.I am not positive yet but I suspect I could go up to 8-10 hours on a charge but haven’t had the chance to fish that long yet.Great value fir the money.

After a couple of months of use this battery is doing terrific. I can't comment on if it will last for years but so far it has performed excellent.I use this in my Playmate Volley tennis ball machine and I was thinking it would be completely acceptable if it kept it running 2-3 hours of use. So far it has been used many times and a few times exceeded 3 hours of use while only getting down to 60% charged (my charger only indicates in 20% increments and I'm relying on it as the measure of charge remaining). It appears like it could last many more hours. This exceeds the lead-acid battery the machine is shipped with by a good margin. It appears to have the capacity advertised based on my usage.I was concerned about buying a battery like this at this cost point due to potential quality concerns. I still don't leave it on the charger overnight or such and keep an eye on it to be sure. But so far this seems to be a viable choice and has given me no reason to doubt the quality.

Good battery for a small solar project

Supposed to be a 20 amp hour battery which should have enough power to run my dogs ball launcher that had a 12 amp battery in it but this thing won’t even though it says it’s fully charged. It doesn’t have any any power to do this simple job

I love Vatrer batteries. I installed two of their massive 460aH batteries in our diesel motorhome - super happy with them! So when it was time to give my daughter's ride-on car a lithium upgrade from the stock AGM 10AH garbage, I came straight to Vatrer. This 20aH LifePO4 battery is getting ~4-5X the duration as the stock battery and additional power too! Highly recommended company and product.

Items arrived packaged well, and on time. Very very very satisfied with the performance of this battery to date. Adequate case encompassing battery core. Will buy again as soon as it’s available!

This seemed like a good quality battery, but it’s less than a year old and now only produces 9.2 volts. It’s been on a high quality trickle charger (Noco) but now it won’t even charge to close to 12 volts. I expected much better life out of a lithium ion battery.

I have an older IBM branded medical-grade SmartUPS 1500 UPS which has been a workhorse for me for about 16 years. The downside, every 2-3 years I have to rip out the SLA batteries, move the cable assemblies, and then safely dispose the old SLAs.I had alot of luck retrofitting some of my other UPS's, but none that required 24V... so this was uncharted territory for me.After getting a pair of these, and attaching them together using 3M double sided tape, the resulting assembly was about 5mm taller than it should be and wouldn't fit inside the UPS, so I used some heavy gauge silicone wire, and hydraulic-crimped an extension harness that allows me to set these batteries next to the UPS... not a big deal... it would have been cool if they fit inside it... but I can live with this given I got a pretty good deal on these.On performance, the good and bad:-Runtime is spot on, if not a little better than I expected.-I was worried about cooling with these being outside of the UPS and not having the UPS fan provide some ventilation for them... but after a couple of full-discharge tests, the batteries appear only warm to the touch.-The UPS does seem to get annoyed by these batteries and keeps flagging me to recalibrate the runtime. I did this a few times, but it just gets "uncalibrated" again... so I'm just ignoring that issue as it doesn't impact the backup runtime. This is the reason I reduced one star from my rating. I think it has to do with the voltages of 2 of these in series or BMS operation.All in all, these are a safe buy... just double check the size to save yourself some of the headache I went through.
