I received a SwapSolar B70 battery for use with the Bluetti Multicooler, but was surprised to see the battery labelled as Lithium Ion rather than Lithium Iron Phosphate (LiFePO4). Is there any reason why Bluetti have gone back to Li-ion for the B70 SwapSolar Battery?
Hi @Erebus
i assume they still use LiFePO4 chemistry. Charging Temperature beginning from 0 °c and the official description mentioned so many charging cycles, that cant be archived by a “normal” li-ion battery.
The AC180T power station, a pivotal component of the SwapSolar ecosystem, introduces a removable battery design. This design allows users to effortlessly replace its two B70 batteries (716.8Wh) from the top, each boasting 3,000+ life cycles and 5,000+ swap times.
Anything to add @BLUETTI , @BLUETTI_CARE ?
Greetings
Erik

@Selfmadestrom yes, that’s why I’m surprised it’s labelled as Li-ion and not LiFePO4, which is of course much safer. Even the user manual states on the cover that it’s Lithium ion.

After confirming with the tech team, the contents of B70 are indeed lithium iron phosphate.
Lithium iron phosphate (LiFePO4) batteries are a type of lithium-ion battery. Lithium-ion batteries have various chemical compositions, and lithium iron phosphate batteries are just one of them. Labeling it as “lithium-ion battery” indicates that it belongs to the category of lithium-ion batteries.

@BLUETTI thank you. It does seem strange not to label it as LiFePO4 given that Li-ion batteries are nowhere near as safe and completely different to LiFePO4.
Is a Lithium Ion Battery the Same as a Lithium Iron Battery?
No, a lithium-ion (Li-ion) battery differs from a lithium iron phosphate (LiFePO4) battery. The two batteries share some similarities but differ in performance, longevity, and chemical composition. LiFePO4 batteries are known for their longer lifespan, increased thermal stability, and enhanced safety. LiFePO4 batteries also do not use nickel or cobalt.
Thanks for the further description.
I can send you the MSDS for the B70. And will record your suggestion in the form.

@BLUETTI thank you. So are you going back to Li-ion across your other products as well, or will they remain as LiFePO4?
BLUETTI has fully launched power stations with LiFePO4 battery cells since the introduction of the AC200MAX model. In the future, we will continue to use lithium iron phosphate.
