I’ll say +1 for r1 wurks. Been happy with my 6400 and 5000mah. One guy at the track reminded me to check battery weight. If your already running a heavy buggy, a lower capacity battery can save weight. In my situation I need to add weight so I get away with the heavier 6400. With that big battery it’s nice to hardly feel any voltage sag, or noticeable power loss, but then again I’m not the best or pushing abilities more then my competition. Power isn’t everything. Some guys at the track, me included, started “reverse cheating” by running 21.5 in 17.5 class. :sweat:

And maybe a dumb question but how do you charge to 4.35 volts for the 7.6v batteries?

By choosing the HV setting or manually changing voltage settings. Depending on the age of the charger, it may require a firmware update - or in worst case might not support HV at all.

Last time I spoke to Danny, he was trying to get some shorty cells up to his standards. It's been a bit of a wait for all of us who are hoping to get some shorties from him.

you have to get a charger that can charge to li-hv specs. The extra gains technically aren’t roar legal.

I definitely should have done more research when I bought my charger. I checked and was sure that it said lihv capable but apparently it’s not. Guess that’s a whole new discussion on what charger to buy 🤦‍♂️

If you're running a stock class it's probably not legal to charge to HV specs, so just stick with what you've got.

Which charger do you have?

I believe Danny got fed up with ROAR.

Your Lipo isn't a Lipo. It's a LiHV (Lipo High Voltage). They are essentially the same, but the manufacturer uses cells in the LiHV that can take extra charge. You are effectively over charging them.

I currently just have the Hitek X1 dual charger. The track I race at doesn’t have any regulations on the battery but even if they did I think still want to invest in a better charging setup and one that can handle lihv, possibly an iCharger DX6 DX8 or something like that. My 2 sons race and we just got a short course truck to race in the modified class.

I dont think theres a person who regrets buying an icharger. One thing to remember is you will need an external power supply. Honestly, most are just server power supplies "hacked" into being able giving out their full power. Power supplies dont have to be expensive. If your only doing 2s 12v power supply is more than enough. I went with an amazon cheap 12v power supply thats rated for 30amps. Im sure theres losses that dont let me actually get that high but i never had the need to go that high. Also if you're charging two at a time your power is basically "halfed".

Thanks for the advice! That makes up my mind to get an iCharger, not that anyone needed to twist my arm or anything. I also need to learn more about how to properly discharge and store my lipos especially with the higher price that goes along with the higher end lipos that I plan to purchase.

Indeed no LiHV or an option to set 4.35v per cell. Problem is that Hitec has many X1 models so probably you did read the specs of a different X1 charger.

That’s the one
