Which motors do you use in Seraph?

[daveimi]

I thought at first they were wheelchair motors lol. Are those hubs home-made? And is it your own wheels you use with mountain bike tyres on?

[daveimi]

That's cool, do you ever get wheel damage with them being exposed? I want to have exposed wheels on my heavyweight thwacker but worried about Thor etc.

[daveimi]

Haha good point!

Thanks guys if I go for Li-ion I think I will go for that charger

Grant
Can you, (in the event I go for LiPo,) recommend batteries, supplier and charger for the larger size packs? the 6s 5000 35c,
I am hoping to run the next robot on only 22.2V so I was thinking of going for 2 packs in parallel. I have a cellpro 10s charger but would only charge one battery at a time!

This is a random question, but after being uber impressed with Seraph at Doncaster I wondered if you had any pictures of the insides of it and like how it goes together and everything You can tell me to buzz off if you want to lol I was just really curious and I didn't get chance to get a good look at it

We got a few chargers. 2 4 channel ones

This is the 4*100W

The older, 4*50 W

Thanks for that but I must confess bending small 3mm Stainless steel parts is just not possible in a shed with a hammer and get it this neat.
I had to go to an engineering company that specialises in this type of work and they had problems with the holes stretching close to the corners.

Progress yesterday, sorted out motor mounts and hub position the 12mm stud bar is crude but shouldn't bend.
