My problem is that i feel that my decent cells are getting hammered and it is a struggle to get them charged after work for racing at 6.30pm.
A few questions.
1. How many lipos will i need for 4 rounds and a final. Normally about 20 mins between rounds(smallish club!)
2. Can i use my Much-More charger Platinum edition to charge them?
3.What else will i need for balancing?
4.Do you just top up the lipos after a race?
5.Do we yet know if lipo performance is affected with this kind of use?
Any suggestions will be much appreciated.
Cheers

I'll start with leting you know, ive only run Lipo once, borrowed cells of Mark Christopher (thanks MC!) and was astonished at just how easy it makes racing again - no need to molly-coddle them like we are with Intellects.
Also, bare in mind, if you are running something like a 5.5 with Nimhs, then with Lipo you'll need a 6.5 and its still likely to be faster.
1. Likely just 1 pack
2. Sausages
3. Less beer, good shoes, maybe a long pole.
4. Yes, start the day with the packs charged, go and race (or practice for 5 minutes (no more)) and go back to the pits, put on charge > go and marshall. The cells will be fine treated like this, no need to discharge. Its advised to run a voltage cut on the ESC, but not essential if you have faith in your ability to not dump the cells in the car (this is baaaad, its like crossing the streams!).
5. No affect known of yet, Mark Christopher is more experienced to know, but TomC ran a pack of his which had seen months of regular use without balancing, and the performance from them was still amazing - no different to newer ones (of the same make/spec) in my car.
Edit:
3. There is a gizmo which plugs into the cells and then your charger plugs into the gizmo, and so continuosly balances while charging/discharging. Or leave the gizmo plugged in on its own to slowly balance the cells.... but this seems less important than doing it with Nimhs, time will tell if there is a risk of damage through not balancing.... Mark Christopher will remember the name of this gizmo, it was something he was showing me last Sunday.
