2C / 10 amp charger?

[Cassp0nk]

Anyone know of a charger thatn can charge a 4900 or 5400 rate at 2C (which trakpower claim is fine for the first 95% of the charge on their lipo packs).

Even the Bantam 6c which is fairly pricey has a max of 6.8 amps, whereas a 5400 at 2C requires 10.8 amps! Trakpowers own charger is limited to 5 amps as are most others I've seen.

This is close, topping out at 10A:

It was recently reviewed in either Radio Race Car or Racer (get both and can't remember!)

Thanks for the link. Reading that, its dawning on me that the limit is possibly power supplies here as the bantam is only 5amps from its internal 240 supply. I guess a 30A power supply is going to cost > 100 quid itself.

So back to the drawing board on this one :)

why would you want to charge at 2c???!!! A 4900 or 5400 would last 2 runs without charge inbetween easy in a 4wd and you should have plenty of time to top up inbetween runs...? Charging at 2c isnt going to have any real benfits... more likely to have an accident!

For bashing as well as racing!

theres really no need to charge at that rate or waste money on chargers/power supplies, 1c is fine dude especially if just bashing, from near flat it only takes around an hour to get a full charge that will last ages...
just get another lipo if you want more runtime... would be less costly

Yep I'm coming around to your way of thinking now I've looked into it.

Roughly how long can I expect a 4900 cell to last with a 6.5 motor? The guy at M-K-Racing mentioned 15 minutes which is why I was thinking I wanted some quick charging. Is 15 a bit conservative?

the bc8 dc will charge two packs at the same time at 9 amps each, however id not recomend 2c as it will shorten the life of your pack

[glypo]

MK is always spot on.

Yeah 15 minutes sounds about right... and it's ages! Depending on hows it's driven it could last a little longer.

Blimey can't you remember back on the old days people were lucky to get 6 :)

Been using the cellpro10s charger for about 4 months now, great charger that's focused on safety, if you connect something wrong, or don't have a balance lead attached it won't charge. Excellent support from Aurrora too. Does a 10A charge on the TrakPower packs without any problem.

You only need a big expensive supply if you are charging lots of cells, I use a Ripmax 20A psu (£40) and in theory I could still charge 6 cells (3 7.4V packs) in series at 10A before I maxed it out. If you have the pc connection lead you can tell it how good your psu is and it limits its input current accordingly.
