Did you start at a 5a charge? The amps will drop as the batt voltage gets closer to 8.4v (full)

yoshimonster

do i start charging a 5amps on balance mode chargeing mode or what?
it is only my first time chargeing and im chargeing on a imaz b6-ac
and how long will it tack it charge on 5amps?
its a 2 cell battery lipo so shouldnt the top voltage be 7.4 insted of 8.4?

Thanks

hi,

as stated earlier, the amps will go down as you reach the full cap of the battery. After some charges though the battery will be able to take 5200mAh or maybe more.

In regards with your charger's amperage make sure it's power supply is able to give 1C (5A for your battery's case), otherwise the maximum will be your power supply output. the Output on the other hand if the previous is ok I believe you can regulate.

hope it sheads some light.

You seriously need to do some research and learn about lipos and how to charge and take care of them . If you need to ask on how to charge them you have no business using them . There are many forums and how to videos on the web .

Lipos are rated as 7.4v but actually charge to 8.4 (4.2 per cell). A 1c charge rate is 1 amp per 1000mah. So...5000 (your mah) divided by 1000=5a. I always balance charge. It could take over an hour depending on how low the batt is. USE A LIPO SACK!!

hi so now i charge on balance mode on 5amps and i plug in balanceing leads and the output thick leads

yoshimonster

hi just another question how for apart can the voltages be of each cell because at the moment there 0.03 apart of each other

Correct.

Is this with them discharged or charged?

Discharged, that's fine, actually pretty good if discharge approaches 70-80%.

If they've been balance charged, no, they should be within .01 (10mv). Most balancer specs call for cell imbalance of less than 10mv. My better ones come off at the same voltage, the cheaper ones will show some diff and as they age, you will start seeing some imbalance.

You might want to look at your charger and see if its listed for your charger.

also im geting some coging when i take off
a but like ded-ded-ded-derrrr
but after i take off its fine
is my gearing to high or what can i program it to not do it like the launch boost thingy

Thanks
