GOING LIPO out of the Box?
So, the HPI site says the E-Firestorm accepts most kinds of batteries, including "most Lipos". What exactly is involved with getting a new Firestorm out of the box running on Lipo batts? Connectors? New ESC?
I'd like to make the purchase of car, batts and charger in one trip, and I have no idea what is required with Lipos. I'm thinking about just getting a smaller Lipo (2s?) and not a SuperFryer9000, or some batt on steroids.
I have no NIMH batts now, so if the upgrade to Lipo is easy enough, I might as well do it now, runtime is my primary motivation (but I can't say no to the speed...).
Stock ESC can work with LiPO batteries with an exception. By default, there is no cut off functionality available. You 'll need a LiPO cut off module like this [link]http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXPGM8&P=7[/link] to protect your LiPOs from over discharging.
This one is a 2 cell module.
LiPOs won't guarantee longer run times as the that depends on your battery current carrying capacity (mAh). For longer run times, you should switch to brushless motor and esc set up as the efficiency of brushless motors is close to double of brushed motors. You'll 99% not need a cut off module with brushless set up as they have a cut off module built in for LiPOs. 1% : check technicals of the product you buy and confirm if LiPO cut off is available on the ESC.
With a charger for LiPOs, you'll need balancing too.
Some LiPO chargers come with balancers, some don't. In latter case, you'll need a separate balancer too.
If you think you'll stick to only LiPOs, a decent LiPO only changer with balancer should come at about 60-70$.
There are chargers which can charge NiCD, NiMH, LiPO, Li[XX] and also have balancers. Decent ones should cost about 125$ +. e.g. Hyperion eos0606i. [link]http://www.cheapbatterypacks.com/?sid=1122512&pgid=chrg&scat=LIPO[/link]
