    • 12V 5200mAh Lithium Battery with 12.6V 1A Charger
Size: 1 Pack
Received one 12V 5200mAh Lithium Battery with 12.6V 1A Charger, in non-retail packaging. I wanted to make my own portable little bluetooth speaker for a fun little project. Something to listen to out in the garage or sitting out on the back patio. I used a little amplifier board and a re-purposed enclosed speaker system from a large tv. I wanted to be able to power this with a battery. I had a pretty rough setup- the board was just rubber-banded to the speaker and I was powering off of a 12v tool battery (bare wires just jammed into the battery pack). After spending enough time listing to music and podcasts, I decided that this set-up actually sounded halfway decent and I wanted to make a proper enclosure and battery connection. Something a little more sophisticated looking, haha. I wanted to have a battery system that had a clean method of charging and a BMS for safety. This pack was a home run for my little speaker set-up! Absolutely a piece of cake to connect. The battery life is phenomenal for my needs, and the performance on the 12v board is rock solid with this battery pack. The charger is sloooow, but I do appreciate that they included one. I like the different barrel connectors that are included, it adds versatility to the rig. I've not taken this pack apart, but overall it seems to be very good quality. Some of these types of packs seem suspiciously lightweight for the number of batteries that would need to be used. It makes you suspect some fanciful story-telling is occurring with purported power ratings. I don't get that feeling at all with this pack. Overall, I am super happy with the value for money on this one. I'd recommend this! ... show more

    • Compact 12V Battery Pack That Works Well for DIY Electronics Projects

I picked up this 12V 5200mAh lithium battery for a few small DIY projects, and so far it has performed exactly as expected. The battery is compact, lightweight, and easy to integrate into projects where a full-sized sealed lead-acid battery would be overkill. The included charger is a nice bonus and makes it a true plug-and-play setup. I was able to charge the battery right out of the box and start using it without any additional accessories. The battery provides a steady output and has worked well powering low to moderate power 12V devices. I've used similar battery packs for LED lighting, small electronics, and portable projects, and this one fits that use case nicely. The built-in protection circuitry is another feature I appreciate. Knowing there is protection against overcharging, over-discharging, and short circuits provides some extra confidence when using it in DIY builds. One thing I can't yet verify is the long-term cycle life, but initial performance has been solid. The battery holds its charge well and hasn't shown any noticeable voltage drop during normal use. Overall, if you're looking for a compact rechargeable 12V battery for electronics projects, portable equipment, LED systems, or hobby applications, this is a convenient and practical option that offers good value for the price. ... show more
