Hey @Holden_man I am looking to fit one of these to my 17:56-2 OB in a few months and the best price I can get just the unit for is about $1600, so if they are charging you $1500 which includes install etc thats a pretty good deal I think, just remember are they going to be Lithium batteries as the new model Manager 30 is coming out in the next few months and will support Lithium as well, where as the current model won't be able to be upgraded......I think they are pretty good at what they do
Hey @Holden_man I think you would be pretty safe with the RedArc BMS, haven't heard of any of there products failing based on the real life testing etc they do with them, (just to confirm no affiliation just really like their products )
