Faster NiMH Chargers?
I recently bought myself a drfit car but there is one downside to it. The charger. (Boy, big suprise on an RTR.) Like all RTRchargers, it takes 8 hours to charge a single 7.4v, 1800mAH battery. Quite frankly, I cant stand that and I think its stupid companies include such slow, weak chargers.Iveonly owned it for 2 days and have used it a whopping...2 times.I expect that from a 1/6th scale Hummer from Toys R Us, not a big expensive hobby grade drift car! Ok, so after my rant here is what im really came here to find out:
The battery I have is a (stated above) 7.4v, 1800mAH, NiMH. Im looking for a charger that is going to charge it up somewhere around <5 hours. I only found one charger that suits my needs: http://www.rcplanet.com/Hobbico_2_Ho...p/hcap0117.htmButwhen I startedreading up on it more, I found out it only wants to charge NiCd batteries. Does anyone know of some fast, cheap chargers that wont break the bank? I just dont want to spend that much on this battery to charge it because its the lowest powered battery that could have been given with this car. (My Mini T has a higher mAHthan this thing and the Mini T battery is an NiMH too.)

RE: Faster NiMH Chargers?
Couldn't see what amps that charger puts out.
Do yourself a huge favour. Buy a lipo charger ( it will do all chemistries) and a 2cell lipo. Read up on how to charge and use them.
1hr charge times will be the max and you can grow with it. 6min charge times are achievable!!

voltage is voltage, the nimh pack you have when charged is 8.4V, as is a 2s lipo. The 7.2V on the label is the nominal voltage on lipos the nominal voltage is 7.4V all these are is manufacturing descriptions about the pack.

Capacity is not a factor. As stated above the peak voltage of 2cell lipo will not hurt your esc. The advantage of lipo is voltage stays steady through out the run so speed doesn't drop however because of this you need to be careful not to over discharge them. Also storage and charge can be dangerous e- as can crossing the road!

I forgot to add you need a low voltage alarm or cut off with lipo. If this is your first go at lipo then this is very important takes a long time to get timing right too not use alarms or cut off's

Capacity in mah does not matter. The motor will draw the current it needs. As long as the battery can provide the rate of amp draw the capacity will only determine how long it can sustain the delivery of the amp draw.

Oh ok. I see. I think I will just stick with this setup for right now though in the interest of price since I can just get more LiPos later on and use the same charger. Thanks.

RE: Faster NiMH Chargers?
that alarm would work, there is maybe the same but less cost ones.
I think i would choose a charger with a display so you can see what's happening with the battery rather than one with leds. For batteries this size you don't need a powerful charger.
Battery i'd choose the small capacity nano techs. 2200mah rather than the venoms. google N2200.2S.25.
