KBT 12V 1200mAh Rechargeable Li-ion Battery, Bare Leads Wire Replacement Battery Pack with Charger Compatible for 12V Devices RC Car, Boat, Robot, DIY, LED Light Kit

Purchased this battery for my trip-wire car horn camping alarm. The horns were intended for cars undoubtably, but hey I’m a DIY guy. The horn is rated at 12v-5amps(watts never tested by myself ) so when I found this battery I wasn’t sure if it would be powerful enough. Turns out the battery worked great, although the horn doesn’t reach the maximum loudness probably due to the low watt output, it is still very loud. 12v train horns don’t work with this battery, but 14v does. Battery charges fairly fast and I haven’t encountered any heating issues while in use or while charging. Battery and charger are light weight which makes it perfect for my hiking and camping expeditions. Very pleased and will buy more in the future for other diy projects. Shipped fast as well.

Perfect for powering decoys.

Nice battery. As others have said, no relevant instructions on charger, but research elsewhere suggested, and experience now confirms, that it's basically plug into power outlet, connect battery and wait until led on charger changes from red to green to show full charge. Battery life and longevity as yet unconfirmed.

Works great for my LNR Precision Mountain Topper transceiver. Will last an entire overnight POTA activation (and lots more) on one charge. Perfect voltage for the Mountain Topper. Plugs right in.

Battery looks well made and is working well. I like the connector arrangement. The charger is a little anemic. Takes longer than I would want. It does work fine though.

I bought this as an experiment for a less expensive alternative than AA lithium batteries for my trail camera. I made a small box to protect it from the elements. It has been working flawlessly for a couple of months and a couple thousand pictures. I just take it out and recharge it periodically.

I’m sorry, but I love this battery. Charges pretty quickly, but lasts a long time, a little “pricy” for my model building budget. I originally bought this battery to power the Arduino in my (self printed) 1/1000 Crossfield Class Federation Starship. But I liked playing with it so much I have yet to close up my U.S.S. Discovery. Our neighborhoods power went out for three days. I took this battery, about 100 leds and lit up our (above averaged sized) front room. We had three nights with the kids and my mother-in-law playing games, doing puzzles or even just talking. I still wish I had a generator though, so don’t go thinking you can power your refrigerator with this. But if you are thinking that chances are you can’t read anyway so…

Built a boom box and this this last forever

Funcional y practico actualmente la utilizo para mis luces auxiliares instalando los focos

Excelente, ahora a encontrarle un uso, solo pido para probar productos y entretenerme, soy jubilado y pues ya no hay que hacer
