I used LiPo batteries I bought for RC electric planes to power my K1 and K2/10 tied to a 50W HiPacker Amp with no issues at all. They were meant to deliver very high current (40A) for relatively short duration (about 15 minutes or less), but some of them lasted for 5 years powering the

Don't know how much you've looked at these Phil. Almost without exception, they provide USB "phone" charging and other low-current (compared to car-starting) outputs. They're not optimized for running a rig (or a laptop or a phone) but they do have a stack of lithium cells and some

Just bought a second one of these. Like UPS batteries, starting draws a ton of current all at once. The intended use will limit the life of the battery. I have a Bolt Power D28, which has two USB charging ports, and an outlet that can be different voltages from 12v to 19v -- it'd run a

I'm seeing a lot of good deals on these Lithium battery, emergency "car starter" packs. They're typically rates from 12000 to 24000 mA-hr, or, as we're inclined to call them 18 to 24 Amp-Hr. Prices vary from about $40 up over $80. They come in a nice durable case with a charger and output
