Its input accepts 5–14 V, and charging is adjustable up to 3 A. That makes it a candidate for battery-powered 5 V projects, including Raspberry Pi 4 setups, provided the battery, wiring, and cooling can support the load.
What the AmpRipper 4000 does
The AmpRipper 4000 v1.0 is a charger-and-boost module, not a multi-cell battery-management system. It charges one lithium cell (1S) from an external 5–14 V source and boosts that battery’s voltage to a regulated 5.2 V rail. Kickstart Design lists Arduino, Raspberry Pi 4, Teensy, and other 5 V devices among its intended applications. See the official product page and Kickstart Design announcement.

Can it power a Raspberry Pi 4 from a battery?
It is designed for applications that include Raspberry Pi 4, and its 5.2 V, up-to-4 A output gives a project a substantial 5 V-class supply. But the 4 A figure is the board’s stated maximum, not a guarantee that every battery-powered setup will sustain that current. The cell’s discharge capability, connector and wire resistance, load peaks, and heat all matter. Check the Pi and attached peripherals’ actual demand and ensure the selected cell and wiring can safely supply it. Kickstart Design describes power-path management that keeps project power from being interrupted when the battery or charger is removed; that is the manufacturer’s stated behavior, not an independent test result.
Recommended Free Tools
Choose and connect the battery carefully
Use a single-cell 3.7–4.2 V Li-ion or LiPo battery. The “1S” designation means one cell in series; “1S[N]P” allows one or more cells in parallel, while the pack voltage remains that of a single cell. This is not a board for a multi-cell series pack.

The board uses a JST PH-2.0 battery connector. Confirm the connector’s positive and negative positions against the board labeling and the battery lead before plugging it in; connector shape alone does not guarantee matching polarity. Reversed polarity can damage the board or battery. Also verify that the chosen battery is suitable for the intended charging rate and load; the listed 3 A is a maximum adjustable charge rate, not a required setting for every cell.
Power input, output, and monitoring
Kickstart Design lists USB-C and through-hole terminals as power-access options. The input source must fall within the specified 5–14 V range. The boosted output is 5.2 V, so check the voltage tolerance of the device and peripherals you plan to connect rather than assuming every product labeled “5 V” accepts the same range.

Battery monitoring is available over I2C through a MAX17048-compatible interface. This gives a microcontroller a way to read battery information; it does not turn the AmpRipper into a multi-cell protection or balancing system. The product specifications do not establish a particular software library, register map, or battery-percentage accuracy, so confirm interface details against the manufacturer’s current documentation before designing firmware around them.

1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsPlan for current and heat
For a sustained high-current design, size the battery, wiring, and connectors for the expected current, and account for heat in the boost and charging circuitry. Keep the module ventilated and evaluate temperatures in the completed enclosure under realistic load. Kickstart Design lists an optional heatsink/fan kit, but the available specifications do not provide independent efficiency, thermal, or runtime measurements. Runtime therefore depends on the battery capacity, load, and conversion losses; there is no single runtime figure established for this board.
