That looks like a Gucci version of the one I bought. It’s dressed up in a panel mount package whereas mine was a bare PCB. It’ll still need housing in a waterproof box. It might actually be easier to house the PCB version than the panel mounted version.

I reckon it’d last about 30 secs🥴

[jeffstevens763@g]

I ended up wiring my 8 and 12 ah battery together in parallel under my seat.
Larger tupperware box was also required.
Voltage is fine now with no overcharging.

did the buck converter not work on a single battery then Gordon?

Hi Jeff.
The buck converter did work but it was a tight squeeze to fit it and the additional wiring into the small space inside my waterproof under seat box.
I wasn't convinced that the wires wouldn't come out of the connectors on the buck converter when the Sib was bouncing around in a chop. They are not the best connectors and the wires are really close together. I wanted the a bit more amps too, for when I'm away with the 6hp which doesn't have a battery charging circuit so I went with joining the two batteries. I added heavy cables and connectors for connecting the bravo pump to blow the Sib up with as well as the 12ah battery was used for blowing the Sib up previously.
Jeff are you coming up for H.H's get together in June?

finally got round to sorting this into a box trouble is there wasn't any destructions for set up any tips before i just play with it

Have a look on YouTube Jeff, that’s where I got my information from.

Cheers Dave there is a vid which helps but I wanted instructions for the settings which I’ve found I’ll put them up when I fire my laptop up

Mine isn’t as Gucci as yours, it uses small pots to set the various outputs. I set mine to 12.6V & 3A max. These are the settings for the battery. There are a couple of settings to set how it behaves on power up too.

Looking at it seems easy enough this has a thermal cut off default setting is 110 degrees down to 80 degrees minimum which is handy.

just incase someone buys one same as mine with no instructions

This is too low for lead acid to prevent sulphation or allow a full charge, that's the battery resting voltage. Float voltage is typically 13.7v and charging voltage 14.2-14.7v

Yeah, but mine’s a lithium. Hence having to go down the bespoke charging voltage route[emoji6]

There's a right way and a wrong way.
I found this a useful diagram:
