This BMS has no ON/OFF switch, if your need switch for your battery,  please order other BMS on our website.

Intelligent lihtium battery management system/PCM for 7S, 8S, 9S or 10S Lithium LiFePO4, NiCoMn, LiMn2O4 etc diy packs. You can program the smart BMS/lithium battery on your computer and view all the parameters via your mobile(The Android APP can slightly modify parameter for the BMS while the IOS APP can only read datas and cannot modify data from mobile). We also provide smart BMS with larger serial from 10S~15S, 16S~ 20S PCM and 20S~ 30S BMS with software and mobile app control. 

This smart BMS use the same COM for charging and discharging which means the charging current can be equal to the discharging current(but we don't sugget to charge with large current because it is not good for the battery). If you  need a battery charger for your diy packs, we also provide customized lihtium battery chargers.

About thickness of the BMS, if the BMS current is large, then it will be 17mm thickness; if the serial number and current is small, then it is 10mm thick.

BMS dimension: 60 x 140 x 10mm with current <50A; 102 x 150 x 17mm with current ≥60A.

The new BMS is compatible with 485 and UART communication port.

If you  need to pre-check the software or app for the BMS, please download from here: smart bms specification

This is a smart lithium battery  management system(BMS) which can be used for either Li-ion batteries or LiFePO4 batteries. It can use for 11S, 12S, 13S, 14S or 15S batteries. You can program it on your computer and view all the parameters via your mobile(The Android APP can slightly modify parameter for the BMS while the IOS APP can only read datas and cannot modify data from mobile) when outside. The battery pcm has been upgraded with alloy plates for better heat radiation, but the connection of the PCM has no changed. If you need the bms communication software, app or connection diagram, please download from here: details and docs of smart BMS. 

We also provide ohter intelligent lithium battery BMS with larger current from 7S to 10S, 16S~ 20S PCM and 20S~ 30S BMS with software and mobile app control. 

The battery BMS is with NTC temperature protection, short circuit protection, over/under voltage protection, over current protection etc.

This Smart PCM use the same COM for charging and discharge which means the charging current can be equal to the discharging current(but we don't suggest charging current to be too large because it is no good for battery). We can also provide customzied charger which compatible with the smart BMS.

If you are going to install the battery with casing which has an ON/OFF switch, then you may need the BMS to have a ON/OFF function leads for connecting to the case's switch. In this case, you can choose the ON/OFF switch for the BMS.

The Smart BMS has upgraded. It's compatible with UART COM and 485 COM.

Smart BMS for 20S, 21S, 22S, 23S, 24S, 25S, 26S, 27S, 28S, 29S, 30S LiFePO4 or Lithium-ion batteries. You can set the battery parameter with your computer or cell phone. The Android APP can slightly modify parameter for the BMS while the IOS APP can only read datas and cannot modify data from mobile. The max current can be 100A for this BMS.  By the way, please set the recycle capacity to be 80% of the rated capacity/actual capacity. If you need the software, app and connection diagram,  please download from here: Smart BMS software/app/diagram.

If you need a charger for the smart BMS, we can also provide: customized charger.

Smart BMS for 16S~20S LiFePO4 or Lithium-ion batteries. You can check or modify your battery parameter by your mobile or computer The Android APP can slightly modify parameter for the BMS while the IOS APP can only read datas and cannot modify data from mobile. The max current can be 50A for this BMS. If you need the programming software/app, smart PCM connection diagram, please download from here: intelligent PCM software/app. 

If you also need a battery charger for the smart BMS, we can also provide customized battery charger to you.

BMS for 36V Li-ion ebike battery with countinuous discharge current being 20A. This BMS is small in dimension(L*W*H: 65*35*9mm) which you can install it into many different battery cases. If you want to make a 5V output for charging your mobile or ipad, you can add a 5V1A USB PCB when ordering the PCM.

The battery BMS has a ON/OFF switch, if you don't have swtich for your battery, you can just solder the two switch wires together.

The battery BMS also has a high temperature protection sensor; if the battery is too high in temperature, the BMS will cut off power to protect the battery.

With this 5V PCB, you can make a 5V USB output from your battery. We use this Decompression PCB for our Hailong-2 battery USB output, tigershark downtube battery USB output etc. This PCB is suitable for 8V-63V lithium batteries. Harness will be included.

The USB port does not include with the PCB, please be noted. The USB output is included with the battery case. We will solder the harness before shipment if we get to know which  battery case you are going to use; different cases require different connection for USB output, if the harness is not soldered when you get the item, please solder youself with the correct connection.

If the connection is wrong, there will be no output for the USB port.
