How high can you go on voltage?

[joeling]

Hi,

I just discovered this thread. I'm thinking (or on the verge of) going for HV & lower current setup. I live in the tropics & the heat from lower voltage - high current setup really causes havoc (fried 5 esc as proof). I am also also in the same shoes as knotted. I want to try 8S with a 12XL or 1940 10wind on a 1/8 buggy. The esc I'm comtemplating is either a BK3695 or BK36120. However, I'm wary of the 36120 as somehow, it can only do 42000rpm max. (info from Mike's store).

In addition, a Lipo under load is likely to drop some voltage. From my limited expereince looking at my eagletree data logger using some Kokam 20C cells, I see something like 3.2V per cell. If one is to use 8S under load, the total voltage will be approx. 25.6V. Is this logical ?

Personally, I think higher voltage & lower current is the way to go for a more stable system at least in my part of the world. For now, it's still all theory for me. I will try & find out soon enough.

8S 4000mah capacity should be similar to 4S 8000mah with less losses due to heat. that's waht I want to try out next.
