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.
