5S or 4S (5S for sprightly performance, 4S if you have a tight track, and need more controlability).

just trying to work this out is the motor more efficent if th wh is higher or lower?

Ya the higher the voltage the more efficient so cooler system and better milage.
Gnr racer: depends, what run time are you shooting for in that buggy? |

the Hyperion 5cell 5500mah is 745g! where as the 5cell 4200mah is 561g I did read on rc tech that it is recommended to keep the lipo weight in the Losi buggy to less than 600g so im not to sure if the 4200 would suit the conversion better |

Right. Higher voltage is ONLY more efficient WHEN the same power is required (ie overall speed) as the lower voltage set-ups.
A 4S set up geared for 40mph is less efficient than a 6S set-up geared for 40mph. A 4S set-up geared for 40 compared with a 6S set up geared for 60 isn't a fair comparison. So a low KV motor paired with high voltage, geared for x, is more efficient than a high KV motor paired with low voltage, geared for x. I ran a 5S 5500mAh Hyperion in my buggy (XB808) and it went well - the Losi conversion doesn't place the battery in the optimum location for heavier batteries - in this case a custom build would be better. 5S doesn't always give more punch - only if you don't change the gearing or motor from the lower voltage. It's possible to have a faster low voltage car than the high voltage - it's not all down to the voltage - the motor and gearing also play a big factor. |
