JBD BMS

Yes, wall-mounting will save you floor space, but it will be more troublesome to move.

Turn off the meter and charger

We don’t have battery cells in stock in our US warehouse. We can ship it from China if needed.

Yes

We guarantee that we use lifepo4 battery cells, and we have a 5-year warranties. The reason our batteries are lighter is because we have specially customized the corresponding casing for the 150Ah battery cell.

Looks good(y)

This is due to the excessive unbalanced voltage difference in the internal resistance of each 12V battery. It may be better to fully charge each battery and let it rest for a while before connecting the battery packs in series.

Generally speaking, a multimeter has an option to measure internal resistance, or a special battery internal resistance meter can be used to measure it.

I think this is feasible, maybe you can consider the competitive finished product as well.

Yes, lithium battery need BMS protection. Most of the finished battery packs sold on the market will have the BMS.

Lifepo4 batteries can be stored and discharged in low temperature environments, but they cannot be charged. It should be fine if stored for two weeks.

Surprised at the huge consumption of solar off grid systems. Regarding lifepo4 batteries, maybe consider the Cloudenergy brand.

If you need Cloud Energy lifepo4 battery and coupon, feel free to contact us.

Charging depends on the charger and inverter support lithium iron, 13.6V seems a bit low.

Interesting, hope all goes well.

Yes, Cloud Energy has a 48V wall-mounted lifepo4 battery.

It's a great plan, complicated but interesting.

Remember that Alibaba Credit Insurance is the most basic guarantee

Thanks for sharing, looking forward to updates on your solar system.

Good luck to you.

We just don’t recommend that lifepo4 batteries be stored at 100% capacity when not in use for a long period of time. It's fine if you use it occasionally. The lifepo4 battery comes with a BMS, but please note that the power supply should be cut off when the battery is not in use.

If the battery cells do not match, it will cause the battery packs to lose voltage and insufficient capacity. And also need a 24V BMS.

Is the battery discharging normally? It is possible that the overvoltage protection of the BMS was triggered during charging.

Suppose you need 35KWh of electricity every day, a 48V 100Ah lifepo4 battery can store up to 5.12KWh, then you will need 35/5.12=7pcs. A 48V 150Ah lifepo4 battery can store up to 7.68KWh, then you will need 35/7.68=5pcs. This is just a rough estimate, in reality you may need more batteries.

Great minds think alike.

Turn on all the electrical appliances on the RV or drive the RV around a few times?

Choose based on your cost. Generally recommend cost-effective 24V lifepo4 lithium battery.

If you reach a certain number, there are many Chinese suppliers willing to turn the stud for you. Otherwise you can look for suppliers who have turned studs in stock.

For 12V lifepo4 lithium batteries, the general voltage of a full charge is 14.4-14.6V.

Although theoretically possible, we don't recommend it.

Generally speaking, the lifepo4 battery will be equipped with a BMS protection board, and the cigarette lighter port will also be equipped with a fuse. Note that the load power will not trigger BMS protection, generally there will be no problem. However, it should be noted that the cigarette...

Electricity is getting more and more expensive now, photovoltaic with battery charging is very affordable.

May I know how the test results are?

The BMS on the battery needs a communication protocol to communicate with the inverter. Generally speaking, most batteries will come with communication compatible with well-known brand inverters. If not, contacting the service team can basically solve the communication problem.
