The problem I see is that Eco sends no instruction or parts list with the battery combo. There is a 'quick-start guide' for every battery and combo on ecobattery.com for each product.
Uno is guilty too - and
I understand printed instructions are a waste of resources - especially when people refuse to read them
Perhaps these battery Combos could include a business card saying this is us,thank you for your purchase, installation guides are here >
