A portable power station is a mechanical puzzle before it is an electrical one. The battery, the inverter, the charge controller and the display all compete for the same rectangular volume, and the management board is usually the last part to be placed — which is why it often ends up as a stack of three boards and a wiring loom. The JNFN ANT 13PSB folds protection, balancing, measurement and communication into a single fourteen-millimetre assembly for 13-series 48 V packs, with the current path rated at 40 A continuous and 100 A for ten seconds.
The design target was a board a product team can drop into an existing enclosure without redesigning the mechanical layout. Terminals sit on one edge, the sense connector on the opposite edge, and the communication header at the end of the row so the ribbon cable can fold to a display mounted above the pack. Everything else — including the pre-charge path for the inverter capacitor bank — is already on the board.
- Single board, fourteen-millimetre stack: Protection, balancing, measurement and communication are integrated on one assembly, removing the inter-board harness that typically consumes the last ten millimetres of enclosure height.
- 40 A continuous with 100 A ten-second peak: Sized for a 1 to 2 kWh portable pack driving a 500 to 1000 W inverter, with transient headroom for motorised loads such as a compressor fridge.
- Integrated pre-charge for inverter capacitors: The output stage ramps into the inverter capacitance instead of closing onto an empty bank, preventing the connector pitting that appears after a few hundred power cycles.
- Sub-milliampere standby: A portable unit may sit in a cupboard for months; standby current is kept low enough that the pack does not arrive at the campsite already flat.
- UART and Bluetooth on one board: The UART header drives the panel display while Bluetooth serves the phone application, so a product line can ship with or without a screen using the same board.
- Conformal coated for enclosed use: Coating protects against condensation inside a sealed enclosure without adding the height of full potting.
- Passive balancing tuned for small packs: A 13-series pack of 20 to 40 Ah cells does not need an energy-transfer stage; balancing duty is scheduled during the absorption phase and gated by temperature.

Portable power stations and solar generators in the 500 W to 1000 W class are the primary fit, along with camping battery boxes and small off-grid kits that a user carries rather than installs. The board also suits compact 48 V energy modules built into a case with an inverter and an MPPT charger.
Product teams appreciate that the same hardware serves a screen-equipped model and a Bluetooth-only model, which reduces the number of board revisions a small range has to carry.
Each board ships with a sense harness, two NTC probes, a power lead and a pinout card. Units are functionally tested against a 13-series simulator with a pre-charge cycle, and the test record is filed by serial number.
Ordering: Samples available from one piece; production pricing from one hundred units. Connector types, harness length and UART protocol can be aligned with the enclosure design.
Warranty: A 24-month limited warranty covers the board.
