    Charger for 18S LiFepo4

    I was thinking more like 18 cells 18S pack, 18S bms, and 67V charger. this is the simplest way for me, I hope that there is some charger that output voltage can be adjusted. I have at home charger for 48V, he goes up to 60V, and maybe little more, and down to 40V. charger for 16S to 20S will...

    Controller for Crystalyte V-408 hub motor

    I am looking to buy some controller for V 408 hub motor. I have three SLA 12Ah batteries for now, so I would like to use them for a while, they are quite good for now. When SLA batteries will be dead I plan to buy 48V LiFePO4. I would like to buy controller that I will use for 36V now, and...

    40155 LiFePO4 cells mixing with other

    I am looking few mounts for two or three 40115 15Ah LiFePO4 cells, but there is no luck, out of stock everywhere. So i was wondering if I coul mix some other 15Ah cells with 40155? maybe 40165? cells with be connected with bms.

    Recommendations for BMS LiFePO4

    I really dont have any luck this week. but, for voltage regulator, I found at home LM1117T to replace LM350, with 4V 350mA charger i think it will do fine. While I am waiting for BMS to arrive, I am thinking to connect cells to 4+13.2V, this will be 13.2V 60Ah and try discharging them with 0.5C...

    Recommendations for BMS LiFePO4

    not above 25V, current isnt limited, LM is on a heatsink, last week I was charging 56Ah 12V battery, max current was below 2A, LM was a little hot, so I decided to put in 12V fan with 12V limit IC, and 40 Celsius sensor as a switch to turn on/off fan. And today, I lower voltage to 3.6V, connect...

    Recommendations for BMS LiFePO4

    something went wrong with my DIY voltage regulator, output voltage was 3.6V and the bateries were 3.31V, when i connect charger LM350 blowes, I dont know what happened?I think I have spare part. tommarow i will continue.

    Recommendations for BMS LiFePO4

    I just recived LiFePO4 bateries, voltages al all above 3.3V. Now I am thinking to put them all paralel, and to charge them with 3.6V, one day, to balance them, would that be good? aslo I have ordered cheap bms from the link, I hope he will work good.

    Recommendations for BMS LiFePO4

    Ok, thanks for help. I dont understand what is the point of sub port connect? In my opinion with serial port connection charging and discharging is possible through load ( regeneration with motor) but is there limit current for charging battery? Am I right, if someone know? I will try to ask seller.

    Recommendations for BMS LiFePO4

    Is it possibly to use cell log instead off BMS to monitor voltage of the cells, and manualy stop discharging when one cell gets too low. If I see correctly this 8cell log is for 4.0~43.0VDC, my pack is 48V nominal! Is cell-log 8M powered from 4-43V? if yes, I can buy dc-dc step down module to...

    Recommendations for BMS LiFePO4

    Thank you for your answers. Charger has a potentiometer for adjusting output voltage up to a 60V+, so this is not a problem, and this charger is for LiFePo4 and SLA. I have ordered 40155 for my pack. Isnt it better not to charge LiFePO4 to 100%, and disharge them to 20%? This bms balance it at...
