I run this battery in all my starter boxes. It has worked great for me all year. For the guy that asked, I have routinely gone two days without recharging. I don't know how long it will last as I do not have a monitor for it but no problems at all for two days.

I never charged it once and it lasted alllllll day long.

worst that will happen is the motor's take a dump and you have to replace them with something better.

Guess I got to make the switch to LIPO on my starter box. I'm amazed at what I've heard about a 2100mAh LIPO lasting so long. Now I have to figure out what charger to buy, as mine only does NmH and NiCd. Maybe I'll venture over to the electric section and see what those guys have to say.

Well i've made up a deans adapter for my Truggy starter box, put the lipo's in there, and gave it a spin, and WOW , I hope it's not too fast.....

Basically, I'm running 14.8v 3800mah 20C lipo power. Gonna try it out tomorrow, will post my findings

I have 2 4s LiPo packs I use in all my 4 starter boxes (2 for on-road, 2 for off-road). I use heavy-duty velcro tape and Deans plugs on them, so that I can quickly change the batteries to the starter boxes I will use for the day!

It was one of the best acessories I ever bought for my RC's! Don't miss my old heavy 12V gel cells!

One of the LiPos I use is from HT Batteries (HT500), the other one from MaxAmps. Both work fine!

+1... been running the HT battery in my OFNA truggy starter box for a year + now for my RC8. In December I ran a 3 day race (4 quals + main + practice) on 1 charge. Just bought a truggy, a second OFNA truggy starter box... and yes, another HT battery.

Default amps

correct me if I'm wrong but a 2200 mah is only 2.2 amps right? Doesn't seem like enough torque to start those tight motors esp. on break in. Please correct me if Im off cuz I would love to save the weight. 12v gels are 7 amp

2200's have MORE then enough to start w/e you need.

jamminnay...why spend 100$ when you can get the same performance from a 30$ ebay pack ?

I run the same battery in my losi box and I absolutely love it works great at least 2 days of racing

you are wrong

Lipo can generaly by charged at 1C (C= capacity) which in case of 2200mah 2.2A which equals to charge in about one hour (many new packs can be charged at 2C or even more).

Discharge power of lipo is 10C for the worst packs to 30+C of the best packs and thats continuous discharge. Peaks (couple seconds) can be up to 60C.

So average 2200mah 14.8V 4S pack with have discharge 20C cont. 30C peak = 44A/66A peak and thats enough for starter box as they need about 30-40Amp peak.

I got 5000mah 20C/30C pack in one box and 8000mah 10C/20C pack in the other and thats overkill. 2200mah 20C/30C pack is enough Acutally 2200mah 15C will do better than nimh or leadacid.

Also Lipo has lower voltage drop under load compared to nimh or LeadAcid battery
