It looks like Sunsynk has expanded their range of batteries. Who manufactures and brands their product with the Sunsynk name and which is the best and safest of the range.

What would make a good battery?

1/ Type of cells

2/ BMS

3/ Software and the level of access, using the app.

4/ Remote firmware updates.

5/ The type of enclosure, and fire resistance, fire suppression ( how long can it contain a fire, at least 2 hours? )

6/ Internal protection for temperature, overcurrent, voltage.

7/ Built in circuit breaker/isolator, I dont know how they are sold without some form of isolation, that isolates live and neutral.

8/ A clear understanding of dangerous and safe locations to install the battery, if anyone can buy, transport, collect and install a battery, the regulations shouldn't be complex hay stack that requires specialised regulations by skilled people to work out the safe installation locations.
