WattCycle 300Ah Mini Lithium Battery with Massive Power in a Small Package

We have been reviewing a number of items related to power for RV travel, off-grid living, and disaster planning. Key to this topic is the need for reliable Lithium batteries. The battery manufacturers have made significant strides using high quality cells, leading edge battery management systems, and packaging. We recently reviewed the WattCycle 300Ah Mini Lithium Battery and found it to have massive power in a small package.

WattCycle 300Ah Mini Lithium Battery

Something that drew us to review this battery is this battery’s mini size without giving up its massive power. The battery measures only 15.12 x 7.64 x 10.04 inches which is slightly larger than a group 27 lead acid battery. This compact form factor brings large power to fit a variety of RV layouts.
The WattCycle 300Ah Mini is manufactured with grade A+ lithium cells reported to ensure up to 10 years of service life. The built-in BMS safeguards the 12V 300Ah Mini LiFePO4 battery cells against overcharge, over-discharge, over-load, and short circuit. It monitors battery status and ensures battery efficiency through individual cell balancing. The battery can provide 3840Wh high efficiency power output with a maximum 200A current.
The battery can operate in a wide temperature range -4℉ to 158℉ and automatically shuts off at low temperatures.

At the time of the blog, the battery is competitively priced at $599.99 and with the upcoming Black Friday Sale, the battery is listed at $499.99.

Overall the battery met our expectations for a 300Ah lithium battery. With it’s compact size, low temperature protection, and competitive pricing, the WattCycle 300Ah Mini Lithium Battery is a good option for RVs, off-grid, and disaster planning where high power is needed, size is a concern, and budgets are limited.
