This one is 1100 mah but it will get you through an hour main with no problems. Perfect fit in the brass battery tray as well.

Yes. The 1100 mah from Serpent will let you go through a 1-hour main and more. But please be careful, this is NOT like the regular lipos of other cars. I'd suggest you charge it before the main to ensure that your voltage doesnt drop that damages the battery. I have damaged one from racing two consecutive sundays without charging it. This is entirely my fault because I let the voltage drop too much.

I also suggest getting the Xceed Lipo Voltage regulator because it will lower the current drawn from it.

If you dont like it because of dont know where to mount it, I mounted mine between the steering servo and the top deck with shoe goo and a tie wrap.

Hope this helps.

with a full charge, can the 1100 lipo get me through 4 10 min qual and one 30min final?

also, i have a Imax B6AC charger, will this be able to charge the lipo pack, and what sort of charge times are we looking at.

my problem was that my nimh battery lasted the qualifiers, but went dead during or before the main, i have a 2463 Kopropo for the steering and a JR590 for the trottle.


thanks

It will get you through the qualifers with no problem. But my suggestion is to give it a peak charge just before the main. It probably wont take no more than 15-20 minutes to recharge the battery. Theres many variables as how the battery lasts, just like engine runtime. But trust me the battery will last more than a nimh. What I usually do, to prevent all the charging is I qualify with my nimh and run the main with the Lipo. But thats just me.

The lipo doesn't take that long to get full charge, charging times are almost halved or less compared to the normal nimh. In regards of your charger, I cannot say because I'm not familiar with it. All you need to do is find a charger that can handle lipos. In my case, I use the Ice Charger.

No it does not have any provision for balancing.

Make sure you use a voltage regulator and just follow the recommended charge ratings that are on the battery Caution paper

Regarding the voltage regulator = make sure it has a low voltage cut-off. Also, do not store the Lipo if it is nearly discharged. This is IMPORTANT because once it goes below a certain voltage it is ruined and trying to recharge it can cause it to blow up or catch fire.

I have ruined 2 Lipo batteries - one when I forgot to turn off the on/off switch and the 2nd when I did not recharge the battery immediately after the low voltage cut off kicked in.

anyone know where the regulator should go, i remember seeing some pictures a while back somewhere, but if anyone has any pictures of their set-up of the regulator on a 720, that will be be a great help.
