Raspberry Pi BMS communication module

Do you need to know how much capacity remains in your battery? Stay tuned - during Q3/2019 we will announce a communication modulebased on Raspberry Pi project. Together with our CPM1 board, it will bring you information about SoC and DoD of any battery pack from 4 to 16 LiFePO4 cells. It will a

Q&A: BMS123 Auto replacement parts

Question: I have the old version of BMS123 Auto and I need a replacement board. Can you help me?

Answer: Yes! The solution is simple. The OUT and IN boards of the BMS123 Smart are backwards compatible with the previous version of BMS123 Auto.

For the OUT-board you can just use the BMS123smart cell

Sailing Yacht with a 12V/200AH battery bank

A reference project for a battery bank on a sailing yacht using the4x WB-LFP200AH cellsfor the board battery and theBMS123 Smart. The battery pack is charged from the on-board AC/DC charger (35 Amp) and the generator (up to 80 Amp).

3.2V LFP cell initial charging

Question: How should new cells 3.2V 40AH,60AH, 90AH, 100 AH, etc. be formed before first usage?

Answer:The new 3.2V LFPcells delivered from the warehouse are partially charged. Howeverbefore the first use, it is essentialto charge each cell to full capacity. The initial charging should

12V LP battery balancing and charging

Question: Can I charge the 12V LFP battery using a conventional auto-moto charger 12V?

Answer: With most of “cheap” car battery chargers you**cannot**charge the 12V LFP battery. Cheap chargers often end charging at 14V. As a result the LFP batteries are not charg

You must charge the LiFePO4 before the first use!

You must charge before the first use!

We remind all users of the LFP cells and LP batteries that the cells and batteriesMUST be chargedto full voltage levelBEFOREassembling into a pack and before starting to be used.

For the 3.2V cells, the full charge voltage level i

Using BMS to analyze the cell performance

Why is the BMS needed for a LFP battery pack consisting of many cells?

Answer: The Battery Management System (BMS) allows you to monitor the battery pack operation. Since the battery consists of a serial string of many cells, you need to monitor each cell to prevent from deep discharge or ove

Maximal voltage during Initial charge of LiFePO4

I want to make the initial charge of all the LiFePO4 cells to the same maximal voltage level of 4.0V. How can I do that?

EDIT:This article givesthe example of 4.00V charge level. The same information is to applied for charging to other voltage levels: e.g.3.65V, 3.70V,
