LiFePO4 BMS 4S 12V 100A Lithium Iron Phosphate Battery Management System PCB Protection Board with Balance Leads Wires for LiFePO4 3.2V Cells Battery Pack

Old BMS board stopped working, easy to replace with this one. Works perfect

I bought 2 12 Volt 100 AH Lifepo4 Batteries at a Great price after about 2 months 1 quit working after contacting the company they sent me a new Battery I was told to do whatever I wanted with the other battery I cut the case open and tested everything ordered this BMS changed it out and the Battery started working immediately I was able to use the Balance lead wiring just plugged it in and replaced the main power leads working Great. Heavy made and easy to use it's a quality BMS

Like the fact it worked,wiring instructions and app could be better!will update review in a few months seeing that it's only been operating for 6-8 hrs.

Update February 5, 2022: Removed all stars. The cell balance doesn't work. Connected to perfectly balanced cells, charged with it to 14.2V (4S). Cells lost balance completely, so turned off the charger and let it rest for 24 hours, the unbalanced cells voltage did not change even with a single mV after 24 hours at rest. Meaning there is no cell balancing. A BMS without cell sensing or balancing is worthless - even worse - will destroy batteries that worth 10 times more than the BMS. Returning to the seller. Original review before further testing: It is actually a Daly BMS at a better price and faster delivery. The low temp sensor cutoff doesn’t work… not unusual with Daly as well. The packaging is as good as Daly - very solid sealed heavy aluminium housing. As with Daly, the heavy cables are great, but too short. It would have been better to have it with solid large terminals as at any case you need to create your own cables in order to build a reasonable battery. As with Daly, the cell balancing is passive and limited. I would recommend using a 5A active balancer - can be found at Amazon as well. Will update after checking the charge/discharge cutoff at high/low voltage - this is the most critical feature for any BMS.

Does very well balancing cells. Not sure about charge limiting or discharge limiting, but I purchased this to balance my Li-Fe P04 cells and it keeps them within 0.1 volts. Built very rugged and seems of good quality.

3 months and still keeping batteries balanced sense wires are very very thin concerns me

N/A

I needed 4 for this project , had to go to 3 different suppliers for all four. well built , put 40 amps through this bms and did what it was suppose to do .

BMSにつきもののアクティベートに失敗することもなく、順調に導入できました。 アクティベート時に大電流(今回は60A設定でした)で充電開始し、Ｐ－，Ｂ－間の短絡を開放すると 問題なく稼働しました。 16セルですと、電圧測定用のケーブル長が不足し、中継が必要でした。 写真はバッテリーセルと合わせて軽トラ用のアルミケースに設置した状態です。

Good quality

本当に放電電流が150Aだとすると、付属ケーブル6AWGだと細すぎだと思うのですが？

This killed 2 of my 4 cells in a 12v lipo system. POS. Does NOT Keep cells balanced, waste of money.

buen dia, lo lo he usado pero se ve en perfectas condiciones y espero funcione iigual estoy conforme con mi compra
