I have had the same Venom lipos for almost three years! They still run good but I would like a new lipo. The 11.1v 5000mah 50c lipo from Venom costs about $115.00 SPC has the same lipo for around $75.00 seeing if people have had good success with SPC. Venom has an awesome warranty and the lipos are good quality but the priice difference is making me want to try something new. Also SPC lipos can be charged at a 2c rate, Venom only 1c.
