There are some Lithium battery manufacturers that are not suitable to be used with the REDARC charger, however there is not a listing available. For reference, Expion360 LiFePO4 batteries are used within the REDARC fleet, but if you are interested in other brands then it is recommended you consult with the tech support of that battery manufacturer to confirm the compatibility with a REDARC charger.
