At SmarTEC, our custom lithium battery pack workflow starts with your requirements for voltage, capacity and application. Our engineers evaluate specs, select proper cells and design matching BMS and structure. After drawing confirmation, we produce samples for your verification. Once approved, we sort cells strictly, integrate BMS and assemble packs on automated lines. Every unit … Custom lithium battery pack process at SmarTEC
The PCM/BMS monitors cell voltage, current and temperature, offering protection against overcharge, over-discharge, over-current, short circuit and abnormal temperature. Cell balancing fixes voltage drift among series cells to restore capacity and extend cycle life. Most passive balancing only works during charging: it turns on when voltage delta exceeds the threshold, and stops once balanced. Parameters … Lithium Battery Protection Board: Guardian of Battery Pack
Working on a custom 13S2P lithium battery pack project recently. Many customers get confused between UN3480 and UN3481, so I’d like to share a quick note: ✅ UN3480: Lithium batteries packed separately into cartons ✅ UN3481: Lithium batteries built inside plastic enclosures/cases For this project, we will supply the battery pack only, with UN38.3 test … UN3480 vs UN3481 | Quick Guide for Lithium Battery Pack Shipping Classification
Many buyers focus only on battery prices while ignoring logistics. Both sea and air freight are available for lithium batteries with full transport certificates, though they suit different scenarios. Sea freight is cost-efficient for bulk orders and inventory restocking. It needs a longer transit window, so proper advance planning is essential. Potential delays from port … Lithium Battery Sea Freight vs Air Freight: Which to Choose?
Smart battery management becomes essential for modern energy storage and industrial equipment. Our self-developed BMS supports CAN communication, allowing your system to read battery voltage, current, temperature and SOC in real time. SmarTEC supplies custom LiFePO4 and lithium-ion battery packs with CAN BMS. We can adjust firmware according to your protocol requirements. Fast sampling and … CAN Communication BMS: Brings Smart Control to Your Lithium Battery System
Many battery suppliers only assemble packs while buying BMS from third parties. At SmarTEC, we develop BMS in-house. We can customize BMS firmware, add CAN / SMBus communication, adjust protection parameters to match your equipment. This means faster technical response, easier function upgrade and better compatibility for your project. We build LiFePO4 & lithium-ion packs … Custom Lithium Battery Packs: Why In-house BMS R&D Matters for Your Project
A clicking noise when charging your floor scrubber lithium battery usually comes from repeated switching of the BMS relay, not damaged cells. Deep discharge causes cell imbalance and triggers BMS self-protection. Try pulse activation: charge for around 10 seconds, disconnect for 2 seconds then reconnect the charger. If it fails, use a battery data reader … Why Does Your Floor Scrubber Battery Click When Charging?
Hardware BMS (PCM) relies on analog circuits for safety protection. Simple structure, nearly zero software failure risk, easier certification. Drawback: No real-time battery data; parameters are locked after production. Bluetooth smart BMS integrates MCU and Bluetooth, with hardware protection retained as safety backup. It supports cell status reading and fault tracking via mobile phone, speeding … BMS Selection: Hardware Board or Bluetooth Smart Board?
Hardware BMS ✅Pros: No MCU/firmware, high reliability, low cost, strong anti-interference, plug-and-play ❌Cons: Fixed protection parameters. No cell voltage / SOC monitoring, no fault log. Best for: Mass production, special equipment, extreme environments, basic protection only. Bluetooth Smart BMS ✅Pros: Check battery data via APP, adjustable parameters, active balancing, fault log, easy debugging ❌Cons: Higher … Hardware BMS vs Bluetooth Smart BMS: How to Choose
Cell inconsistency is the main reason for reduced capacity, shortened cycle life, and unstable performance of lithium battery packs. As a core function of BMS, cell balancing eliminates voltage differences between individual cells to maximize battery pack performance and service life. Many buyers and engineers are confused between passive balancing and active balancing BMS. In … Passive vs Active Balancing BMS: How to Choose Correctly
