9920/ Lipo?

[neweuser]

I'm soon uping my cells in my emaxx. Probably 16 cells. I wanted to go twenty but think the weight will be more distructive....So my next option would be lipo i guess. I have no experience in these batts and I think it'll cost some bucks as i will need a charger for them too. Any ideas on good lipos to run with my 9920/10xl? Charger? What would run times be? Speeds?

Thanks guys!
