Recommended BMS Models:
4–8 series (supports up to 8 series, corresponding to 12V–24V systems)
In lithium iron phosphate (LFP) systems, 4 series corresponds to a nominal voltage of 12V, suitable for automotive electronics and basic energy storage in RVs; 8 series corresponds to a nominal voltage of 24V, commonly used for RV energy storage, portable outdoor energy storage, and small industrial equipment. For ternary lithium batteries, 6 series correspond to 24V, and for lithium titanate batteries, 5 series correspond to 12V; both are compatible with BMS models in this range.
All models in this range are 8S specifications, supporting flexible configurations of 4–8 series battery packs. Specifically, they include: the cost-effective BD series—JK-BD4A8S4P, JK-BD4A8S6P, and JK-BD6A8S10P; the B Series models with high equalization current—JK-B1A8S10P, JK-B1A8S20P, JK-B2A8S20P, and JK-B2A8S30P; models with special function suffixes—JK-B1A8S10PS, JK-B1A8S20PS, JK-B2A8S20PS, JK-B2A8S30PS, and the QB Series model JK-QB2A8S20P.

8–16 series (supports up to 16 series, corresponding to 24V–48V systems)
The lithium iron phosphate (LFP) series covers configurations ranging from 8 series (24V) to 16 series (48V), meeting the needs of residential low-voltage energy storage, UPS backup power, small-scale photovoltaic systems, electric bicycles, and other applications. The ternary lithium series (13 series) corresponds to 48V, and the lithium titanate series (10 series) corresponds to 24V, both of which fall within the supported range.
This range primarily consists of the PB series designed specifically for parallel connection in 16S configurations, supporting 8–16-cell battery packs. It is specifically designed for high-capacity energy storage scenarios involving multiple parallel packs, Specific models include the JK-PB1A16S10P, JK-PB2A16S10P, JK-PB1A16S15P, JK-PB2A16S15P, JK-PB2A16S20P, and JK-PB2A16S30P. Models with specifications of 17S and above are backward compatible with battery packs of up to 16 series; if you plan to expand capacity in the future, you can directly choose a higher-tier model.

8–20 series (supports up to 20 series, corresponding to 24V–60V systems)
The lithium iron phosphate (LFP) system includes three standard voltage levels: 8S (24V), 16S (48V), and 20S (60V), suitable for applications such as RV energy storage, residential energy storage, high-speed electric motorcycles, and low-speed electric vehicles. Ternary lithium covers 13S (48V) to 16S (60V), while lithium titanate covers 10S (24V) to 20S (48V).
This range includes two specifications—17S and 20S—supporting battery packs of 8 to 20 series, and represents the mainstream voltage range with the highest current market shipment volume. Specific models are divided into three major categories: the entry-level BD series with 0.4A balancing, including the JK-BD4A17S4P and JK-BD4A20S4P; the BD series with 0.6A balancing and charge detection, including the JK-BD6A20S4PD, JK-BD6A20S6PD, JK-BD6A20S8PD, JK-BD6A20S10PD, JK-BD6A20S12PD, and JK-BD6A20S15PD; The basic 0.6A equalization models in the BD series, including JK-BD6A20S6P, JK-BD6A20S8P, JK-BD6A20S10P, JK-BD6A20S12P, JK-BD6A20S15P, and JK-BD6A20S20P; as well as the B series with high equalization currents of 1A and 2A, including the JK-B1A20S15P and JK-B2A20S20P

8–24 cells (supports up to 24 cells, corresponding to 24V–72V systems)
The lithium iron phosphate system covers the full voltage range from 8 cells (24V) to 24 cells (72V), meeting the needs of various power levels, including RV energy storage, residential energy storage, electric motorcycles, large industrial forklifts, and specialty vehicles. Ternary lithium batteries cover the range from 13-cell 48V to 20-cell 72V, while lithium titanate batteries cover the range from 10-cell 24V to 20-cell 48V.
This range corresponds to the 24S specification, supporting battery packs with 8 to 24 cells, and serves as a versatile choice for medium- to high-power applications. Specific models include: the entry-level JK-BD4A24S4P with 0.4A balancing; the BD series with 0.6A balancing and charge monitoring, including the JK-BD6A24S4PD, JK-BD6A24S6PD, JK-BD6A24S8PD, JK-BD6A24S10PD, JK-BD6A24S12PD, and JK-BD6A24S15PD; The 0.6A basic BD series with balancing, including the JK-BD6A24S6P, JK-BD6A24S8P, JK-BD6A24S10P, JK-BD6A24S12P, JK-BD6A24S15P, JK-BD6A24S20P, and JK-BD6A24S30P; The B Series with high equalization currents of 1A and 2A, including the JK-B1A24S15P, JK-B2A24S15P, JK-B2A24S20P, JK-B2A24S30P, and the JK-B2A25SRP with special features

Additional Notes: In the model naming convention, the number preceding “S” represents the maximum number of supported battery strings; the number preceding “A” represents the active balancing current; and the number preceding “P” represents the continuous discharge current rating. The suffix “D” indicates a charging detection function, while “P” indicates enhanced parallel functionality. Models should be selected based on actual application requirements. Protection thresholds vary across different battery chemistries at the same nominal voltage; the BMS must be configured via the app with corresponding parameters and must not be used directly with mixed battery types.
