Overview
The JKBMS PB1A16S10P is an active-balance smart inverter BMS for family energy storage battery packs using LiFePO4, Li-ion, or LTO cells. It supports 7S–16S (Li-ion), 8S–16S (LiFePO4), and 14S (LTO), provides 1A active balancing (Full State On), and integrates Bluetooth monitoring plus RS485 communication (default) for system integration.
PB series inverter BMS models (PB2A16S20P, PB2A16S15P, PB1A16S15P, PB1A16S10P) are upgraded to the latest V19 version; all orders placed after June 1, 2025 are set to version V19 by default.
Key Features

Details
Built for home energy storage packs, the PB series smart inverter BMS combines active balancing with system communications for cleaner integration.
Choose the correct string count and current rating for your pack; the PB lineup covers multiple cell chemistries and stack sizes.
A multi-layer internal design brings together the control board, high-current path, and connector interfaces in a compact enclosure.
RS485 is the default communication interface, with CANBUS and heating control available as customization options.
Bluetooth monitoring provides quick access to pack status, cell voltages, and real-time charge/discharge information from a phone.
App controls include battery type selection and configuration tools, alongside detailed per-cell readings for troubleshooting and tuning.
Layered protections help safeguard the pack against common electrical and temperature fault conditions during operation.
Power modes such as Storage, Standby, and Shutdown are designed to reduce pack drain when the system sits unused.
