Hi, To reduce the use of a generator while Boondocking I was thinking carrying a smaller LifePo4 battery bank on the truck bed. As we use the truck daily for excursions I was thinking to charge this bank with a DC/DC charger while driving. When returning to camp with a full battery I want to...

My Daly Smart BMS 4S (200A) is not registering small loads? I have a parasitic draw around 1.1A/h in my travel trailer. The Daly BMS show 0. My Victron shunt shows 1.1 A. As the Daly BMS does not show small loads it also stop calculate SOC. So big difference in calculated SOC between Victron...

Hi guys, I’m installing 2 x 280Ah batteries in parallel on my boat. Have been running 4/0 marine wires (105C) between battery fuse (400 Ah) and Victron Multiplus 12v/120A/3000W. Typical high draw will be 1800 W when induction top is used. (But would like to size system for the 3000W...

I have got my new EVE cells. Bought stainless steel grub screws. They definitely wobble in the thread. Does not feel like they provide a sturdy connection in a travel trailer. Loctite would definitely stop the wobbling. But the question is will Loctite make the connection stronger.

I have a Victron Multiplus 3000W with 2xSOK 280Ah installed in a boat. That means I switch off the main battery switch when I do not use the boat. So Multiplus is disconnected. Is there any pre charge circuits built in to the batteries? How long does the capacitors stay charged? As my...

Hi, Today I was wathing Will Prowse video on the SOK Battery. I’m amazed that there is not a similar battery box available for the EVE/Lishen 280Ah cells. How cool would that be. a Metal box like that with room for the BMS would be a Big sales succes. i would buy one immediately. Another...

Hi, Yesterday I connected my pack in series and started charging. The BMS came on after I fixed a bad connection on one of the sensor wires. (It is a very thin wire so shit can happen when you crimp) everything is working fine. I use the Bluetooth interface for programming. When I stop...

Hi guys. I have been servicing a lot of lead/acid batteries in yachts over the years. Most of the time the customer changes his batteries before there is a catastrophic event. But occasionally I have seen lead/acid batteries that have had shorted cells that have caused extreme heat and in some...

I finished my compression rack today for 4 x 280 Ah cells. compression will be achieved with 4 threaded rods between two aluminum plates (5 mm) Will use the pack in a travel trailer. I want to reduce the movment between the cells. Do you compress when cells are 10% SOC , 50% SOC or 100% SOC...

I topbalanced my cells in paralell. Then put them together in series. One cell is running away when I get to the knees. Before I reach the knees there are very small difference. It is always the same cell In both ends of the voltage curve. Did set the charger to 14.2V and got a diff of 0.1V...

I have EVE 280 Ah cells that I bought on AliExpress. Did top balance the cells @ 3.65V. I charge them to 3.475 (13.9V) with 2 hours of absorbtion. Delta V goes to 55 mV. The Daly BMS is the only balancing that take place. My question: What is considered an acceptable Delta V for matched...

Hi Guys, My Daly Smart BMS disconnected today when I did run the coffeemaker. (Second time I used a higher load) I tried to restart the BMS with the wake up button I installed. No success. Started a charge cykel with the battery charger. BMS came to life and let current thru. Only problem...
