May I ask what type of battery you have: LiFeP04 battery, lead-acid battery or other. I've also encountered similar problems. Self-discharge is very high, about 30% in a week. The dealer told me that the self-discharge rate of LiFePO4 batteries is very low. Leaving the battery for a period of...

Looking forward to more sharing from you

It seems that professional advice is needed.it's crucial to assess your roof's structural integrity and determine the best location for the panels in terms of sunlight exposure.

I think the built in BMS of the battery is important

In general, 400 watts of panels can potentially generate up to 20-25 Ah of energy on a sunny day, which is higher than the 50 Ah battery's capacity. To prevent overcharging, you should ensure your charge controller is properly set up to regulate the charging process and protect the battery.

Did you build and assemble it yourself?

Hello, I have a problem with the livepo4 200 ah battery. At night I used webasto to heat the motorhome and when it came to 12.5 V the battery was disconnected from the power supply and nothing could be turned on either the converter or the webasto back. Why did it happen that it was...

The voltage of the battery will be slightly lower than at rest. Therefore, to maintain the safety and life of the battery, set the safety cutoff point at the voltage under load.

Do you have any recommendations for warming pads? Which one did you buy in the end and how was it?

It is definitely confirmed that lithium battery rooms also need to be ventilated as gassing can occur. As the report rightly mentions, great films have been made outdoors where the fumes can be emitted safely, but in a non-ventilated room it is a completely different matter. The fact that...

I'm curious to see what the cause is.

I see this reminder every time on the battery sales website: LiFePO4 batteries cannot be charged below 0 degrees, which will affect the lifespan. Finally know the reason. thank you for your sharing!

If the battery pack has a built-in BMS and can connect to the inverter and manage its charge and discharge process, you will not need to disconnect the communication from the other battery packs.

It would be great if there was a charger of this type and the current could be replaced correctly.

Continuous charging should not necessarily harm the LiFePO4 batteries if the charger is designed to work with these batteries and adheres to their recommended charging profiles.

What is the specific reason? Is the BMS system not working?

I recently buyed yed one of LiFePo4 batteries (12V 100ah). After I added a set of M8-Adapter , I connected the batteries with my charging booster (Voltronic VBCS 30/20/250 Triple) inside my camping van. Unfortunately I forget to deactivate the "pulser" first time, which is helpful for...

Hello everyone Does anyone have experience with LiFePO4 batteries WANROY 12V 100Ah? There is a Black Friday sale going on which you can get for €450. Is it worth it? Chrisgraham

How much does it cost to DIY batteries?

您提到的 78A 峰值可能是指逆变器可以短暂处理的短时浪涌。

Car heaters are designed to draw a significant amount of power to provide efficient heating. Solar panels, might not be able to provide the necessary power consistently.

I can't imagine that LiFePO4 alone would cause the explosion.Link
