BMS 10S (36V - 30A) Lithium Battery Protection Module

Lithium Battery Charger Protection Module (BMS) 10S 30A

Ensure the safety and longevity of your lithium battery packs with this robust 10S 30A BMS. Specifically designed for 3.7V Li-ion/Ternary cells (like 18650), this module acts as the “brain” of your battery, managing power flow and protecting against critical failures. It features a split-port design, meaning it has dedicated terminals for charging and discharging to optimize current handling and reduce heat. The integrated aluminum heat sink ensures stable operation even under high-load conditions, making it an ideal choice for high-power DIY projects.

Features

• Active Balancing
• Split Port Design
• Comprehensive Protection:
• Overcharge Protection
• Over-discharge Protection
• Over-current & Short Circuit Protection
• Thermal Management
• High Reliability

Wiring steps:

(1) Collecting the cable to connect to each section of the battery to ensure the effective connection of the cable.

Make sure the cable plug, a single potential order sequentially or sequentially reduced.

The potential order is consistent with the potential order of the socket of the protective panel, and the potential is corresponding.

(2) Welding the B-lead of the protector to the total negative b- of the battery pack.

Make sure the welding point is firm and reliable and the conductive characteristics is good, avoiding solder, easy to conduct electrical objects or leads to fall, stick or contact into the protective plate.

(3) Dock the plug of the cable with the socket of the protective plate.

First, complete the B-lead of the protective plate to the total negative b- of the battery pack, then connect the cable's plug to the socket of the protective plate, ensuring the connection of the cable plug and the socket of the protective plate, without the electrical object or The lead is in contact with the protective board and do a good job.

(4) B + and C- are connected to the positive and negative electrode of the charging interface, respectively.

Be sure to avoid short circuits in the welding process.

Assembly instructions:

1. First, take the battery, difference <0.1V;

2, the internal blocking pair of battery, the difference in internal resistance <5M Europe;

3. After the battery spot is welded, the test voltage is normal;

4, welding the board;

5. Connect the board to the group battery in the order of B0 B1 B2 B +.

Precautions:

1. Please pay attention to the output power to configure the size of the nickel sheet;

2. Be careful not to continuous P + P- repeated short-circuit, there will be circuit voltage spikes, which is easy to cause MOS tube damage;

3, pay attention, do not let the protective plate touch water, easy to damage;

4, welding board, please pay attention to anti-static operation!
