2 cell lipos should not be charged higher than 8.4 volts.

 

I understand some folks do charge them higher but that is pretty dangerous....and it will kill your cells pretty quick.

Kiran.. if you charge the pack with the two cells connected (which I do) you can safely charge it at 5 amps lipo setting.  If you use a balancer its better.

I never charge each separately  why waste time?

 

If you want you can give them to me on Sat I can show you how to balance and charge safely.

Charge it as 1 cell (3.7V) ONLY if the jumper is not connected.  If it is connected, then charge it as a 2 cell (7.4V) Lipo.

From Trakpower's website:

Charging...
Charging LiPo’s is one of the most talked about subjects in the sport, there are a few simple rules which will allow trouble free operation.

Lithium Polymer packs MUST be charged by a LiPo compatible charger.

LiPo’s are different to NiCd’s or NiMH’s in that they do not need to be cycled by a charger at all, unless the capacity needs to be measured. In fact LiPo technology prefers to be partially charged or top-up charged.

LiPo should not be charged below 5 degrees C, below -10 Degrees C, charging can ruin your pack

LiPo’s should not increase in temperature whilst charging, unlike NiCd or NiMH.

When you buy a new TrakPower pack it comes around 70% charged. The pack can be charged from new at the normal charge rates.

Normal charge rates for a LiPo pack are 1C (1 x Capacity in Amps) this will take around 1 hour, TrakPower packs are capable of being fast charged at up to 2C with a TrakPower V-Balancer or other certified balance charger.

ok, thanks. that makes sense, but it didn't say anything about C. what i read said:

"use only a lithium polymer battery charger set to 1 cells/3.7v lipo."

for those who use the trakpower 4800 b44 saddles:

how are you charging them? on the back of the package it says to charge it as 1 cell 3.7 volt but the pack is a 7.4 volt 2 cell.... i set my charger to charge it as a 2 cell 4800 but unplugged it like halfway through the charge when i read the back of the package. any help would be appreciated.

also, did i screw anything up?

No, you did not screw anything up...or rather almost.

the "C" does not stand for "Cell". The "C" actually stands for Capacity.

So when they say "please charge battery at 1C", it means do not charge any higher than the battery's capacity in Amperage. If you have 4800mah, it means that 1000mah=1Ah, therefore 4800mah equals to 4.8Ah and that is your 1C rating. Do not charge any higher than 4.8A just to be in the safe side and make sure you charge the battery in a non flammable surface like concrete cement in the backyard or driveway or if you can already afford it, use Liposack.

I hope that helps.
