I'll chime in. Running brushed yes you have plenty power. As for chargers on a budget lol that can get scary. I can a point you to a supplier of very affordable lipos.same place sells little single pack chargers for around 30 I believe and they'll charge up to 5a.spend lil bread and get a hitec x4(or similar).I have the ac/dc version and it's f'n sweet. J/s.check out valuehobby.com.they sell 5000mah 25c 2s for 18.99a piece. And that's the one with cheap charger. But those packs mentioned are plenty for a 12t slash. I used a couple for a year or so in my 4x4 stampede running a sidewinder with duratrax 3900kv 4 pole.
