Lithium batteries are evolving rapidly, resulting in tumbling prices and new products every few months. At the forefront of consumer lithium batteries for over a decade, Renogy continues to iterate on well-proven solutions, pushing the envelope of what is possible. Its latest super-slim solid-state battery provides 104 amp-hours of energy in a tough metal enclosure only 2.4 inches thick, making it ideal for space-constrained mounting locations.
In my testing, the EV-grade cells withstood the nastiest of corrugations, and thanks to new chemistry, they heat up nine times slower than traditional lithium batteries. I have charged the batteries all the way down to -14°F, much lower than previously possible, and even directly shorting the terminals of a fully charged battery barely induces a tiny spark before the internal safety systems shut down the battery, making thermal runaway and catastrophic fire concerns of the past.
With built-in Bluetooth and an internal shunt, monitoring battery temperature, state of charge, and real-time current flow is a snap with the free DC Home app. With an optional bus bar kit, I have chained two batteries to provide 208 amp-hours of energy, a setup that can be expanded up to a whopping 1,664 amp-hours at 12, 24, or 48 volts. Rated for 6,000 cycles and with an eight-year warranty, Renogy’s latest will keep you flush with power for years to come.
