Batterie life span.

[IDontKnow]

On my Kinghauler I run the Venom 8000mah battery with a low voltage alarm.
The MFU is only used to run the lights and sound as I have a Tamiya speed controller mounted under the hood , onto the two servos, to controll the forward and reverse and it has Lipo low voltage cut off also (cant think of its number at the moment).
I used to have issues with the truck shutting down at some of our outdoor shows due to overheating as thrown in there also is an infrared lighting kit!
Back to the battery, I can run most of the day if not all on the same battery towing up to 11 trailers so in my opinion Lipo is the way to go. I run Lipos in my King, Globe, Aeromax, F350 and my HSP drift car. Only one that doesn't is my Merc only because I need to buy more batteries!

i have tried a mix of batteries in mine over time and for starters i find dynamite battery packs are garbage. i use duratrax dtx 1600 in my trucks where space is limited,they work really great .i ended up using also Reedy Wolfpack 4200...3600...2400 ni-mh and have been using them for the past 5 years.i get around 1 hour of run time without lights and around 45 mins with lights give or take with the larger ones 4200.the smaller ones i use for quick runs in between times when i am getting loaded at companies .i won't use lipo's in any of my trucks i am too afraid of the fact that some will catch fire easily for some reason.but i agree with the statement earlier here ...it depends what you pay for ..there are cheap batteries and a little more pricey better batteries
