24V 50Ah LiFePO4 Battery, Group 24 Lithium Marine Batteries, 5000+ Cycles Lithium Iron Phosphate Battery, Perfect for RV, Solar System, Trolling Motor, Camping

Using one of these 24v 100Ah batteries for a small solar power system.It was well packaged and arrived without any damage. Initial voltage measured 26.2v but after charging it increases to 26.8v. So far I've cycled it a few times and it has performed as expected.Overall, very happy with it (so far). Will update my review after a few months of use to report any noticable changes.

Came in quicker than I thought and was fully charged when I got it

This 20ah battery is more than enough for a few hours of 100-watt field Ham radio operation such as POTA or Field Day. Height lets it fir (just barely) in battery boxes built from the common plastic .50 cal ammo boxes -- but plenty of room alongside it to stow cables, charger, etc.

Worked like a charm

I ordered the 20Ah variant. For a small UPS and a ride-on toy, voltage stays steady under load and bounce-back is quick, so equipment doesn’t brown out like it did on SLA. The built-in BMS handles the basics—over/under-voltage and short protection—and the pack is light and compact enough to mount in tight spots.Charging was straightforward with a LiFePO4 profile (constant-voltage around 14.2–14.6V, no equalize). No charger or cables are included. Post-terminals are on the small side; adding washers made my ring lugs more secure. Not for engine cranking. If you’ll use it in cold weather, expect charging protection to limit or pause below freezing. Series/parallel use is possible on many LiFePO4 packs, but match identical 20Ah units and follow the variant’s spec sheet.

I love to tinker. I have all sorts of projects. A lot of them involve audio, but I have several lighting projects and others around the house. I like 12v systems, and a lot of my projects are 12v, so I'm always looking for power supplies. When I saw this little battery I had to try it.It arrived in a plain box and contained just the battery. It arrived in near-mint condition with a 12.8v charge.This is a nice little battery! I connected an LED pod and it fired right up. I left it running for about 30 minutes and there wasn't any drop outs or failure. The battery charge only went down a little, but I can't yet predict the overall battery life.Overall I'm happy with this little battery and look forward to incorporating it into one of my next projects.

I’m using this 12V 20Ah LiFePO4 battery to run electronics on my fishing kayak. Mainly a Garmin Striker 4 fish finder and TD6E thruster. It holds a charge well for long fishing days, and I haven’t had any issues with power drop or BMS overheating. It’s lightweight, easy to carry, and seems well-built. I like that it has BMS protection, so I don’t have to worry about overcharging or draining it too low, or overheating. It’s a little more expensive than the lead-acid battery it replaced, but the much longer life and better performance are worth it. Bluetooth connectivity would be a nice to have to see capacity from your phone, but has not been an issue for me so far.

Used dual batteries on a two week camping trip and worked as expected. After three months sitting had a charge yet. No complaints.
