I'm coming back to this because I'm looking at spot lights and a dash cam install so wondering if a smart power manager is a better option. So far my thinking is:
1) Wire everything independently direct to battery with spots on a switch
Advantages: Saves a bit of money, one less thing on the bike
Disadvantages: lots of connectors to the battery, multiple live feed taps needed, no fine control
2) Healtech Thunderbox
Advantages: £60, simple set up
Disadvantages: no fine control, limited connections 2/3, 8A max output (but I'm not planning on a sound bomb)
3) Hex EzCan
Advantages: smart control, comes with connectors to wire in non-hex accessories (like innovv)
Disadvantages: £170, might need to buy an additional wiring harness
4) Denali CanSmart
Advantages: smart control, plug and play with Denali lights
Disadvantages: expensive £250+ (although there is a kit for £665 with D2s, horn and brake light), need to buy an extra connector for innovv
So I feel like my options are either start with 1 and build up slowly adding an EzCan at some point or take the big hit and buy the Denali bundle as even though I wasn't going to get a split horn or rear brake light it's the cheapest way to combine everything.
