The advantage is that after a fight I can charge up both batteries for the same amount of time, so even if I don't have time to finish charging I know both packs have the same voltage so are safe to use together in series.
Although, I am not sure if a ballancr charger ballances the packs during the charge or at the end so I don't know if semi charging is dangerous.
I think there is a setting on my current charger that lets me change the voltage it takes the packs to, so I could reduce this so there is plenty of time between fights to charge both packs to this level.

Chargers like the Imax b6 balance when the voltage reaches the set voltage. (4.2V for liPo), it takes compared to "fast charging" ages.

What do people think of 2mm steel on top of 13mm marine ply as top armour for a heavyweight. Do people think that will stop most axe blows from getting through?

[Eventorizon]

I doubt it would take it. One hit maybe but after that the ply's layers would have separated and the steel would be only thing stopping it, and 2 mm steel isn't enough on its own.
Besides, the cost of buying both of those may mean its better to jump straight to 4mm Hardox.

[maddox10]

Weight of 1m² 13mm "durable plywood" is the same as 1m² 1.5mm steel.

Like Alex writes, better aim for 3.5 / 4mm wear resistant steel like hardox.

[Max]

I am unable to afford/use hardox, my options are steel, aluminium, wood or at a stretch hdpe. I'm not sure which material would be most puncture resistant for the same weight. I thought steel and wood would be good as I get lots of thickness from the wood but the hardness of the steel.

[Ellis]

The steel will tend to puncture and partially spread the load on the wood. The result will gradually obliterate the underside of the wood until, as Alex said, it might as well not be there, and you're protected by the thin steel.

Unless you go for much thicker steel (or much thicker wood, but I woodn't (heh) recommend it), HDPE might be your next bet. It will have to be fairly thick but it will absorb the impacts to an extent. 6mm HDPE just about holds out Little Hitter, to give you an idea on thickness.

For anyone who's interested, if you run a 24v Gimson on 36 to 1 ratio with 160mm wheels you get some smoke and a blown 25A fuse.
I may have to turn down the wheels to a smaller diameter

[maddox10]

Strange, In Hannibalito 4 we run 9.6V GR01's with 180mm wheels @ 3S. The fuse is a 40A one, but I tested a 25A one too, and no problem there at all.

[Max]

It could be a problem with the motor, it is one of the dodgy 24v ones. I've got the 18v replacements but thought I'd give the 24v ones a chance first as I don't want the extra speed from the slight overvolting.
I'll test the motor to see where the problem lies
