my battery is a Venom 5400 20C Li-Po an charger is a Dynamite Passport 6S. the battery isnt charging and i need some insight as to troubleshoot which is at fault. heres what i know, i can select the type of battery LiPo/LiFe just fine, then set the charge rate no problem my book says the charge rate indicator should blink at me if the balance plug is not connected, which does not happen. also the balance LED's should blink during charging this does not happen either. my expected charge time should be less than an hour, it was on the charger for several hours this evening and the alert never went off. which is when i realised it wasnt charging.

What charge rate are you setting? A setting of 5.4 amps should be fine (if your charger will go that high).

Can you read the cell voltages through your charger, if so what are they?

dieselmudder · 10-14-2011, 02:27 PM

setting is at 5. and no i cant read cell voltages. should i be able to read continuity through the power plug of the battery? or the balance plug?

Set your charger to balance mode...most likely you are not realizing that the voltage or charging amps are incorrect. Most "Newer" chargers will not let you charge a Lipo at the wrong voltage or amps due to the fire theory.

Just curious, did you push and hold the start button until it beeped to start the charging cycle?

I just went through the same deal with this charger, learned I wasn't using it right...

SINister · 10-14-2011, 07:46 PM

Has it worked before? My last charger just stopped peaking batteries.

if your battery has damaged or disconnected cell(s) your charger will believe it has a balance lead connected but for a safety precaution it wont actually charge.
I have lots of electrical expierience and i would say this is likely your problem as my charger(s) do that if there is a cell problem.
PS:it could be that a cell is below voltage

off road again · 10-14-2011, 08:04 PM

if you have other batteries start by seeing if they will charge

dieselmudder · 10-14-2011, 10:35 PM

no, at the time this is the only LiPo battery i have. and now the battery is flat ass dead. i hook it up to my Night Crawler an the led for the ESC doesnt light, the LED crawler lights dont come on, an it doesnt make any kind of sound when i try to actuate speed or steering. so do i gamble on buying another Lipo? i could get one for my MRC which would be an upgrade anyway. but dont really wanna piss money away chasing ghosts i dont even know anyone locally that runs electric rc, my buddies all run nitro.

Go look in the regional forums and find someone close to you. See if they'll help you out.

Check your battery for broken leads using a voltmeter. Check the voltage at the main wires and then check each cell at the balance connector (you should see the pin through a hole which is where you would place the DVM probes.

off road again · 10-16-2011, 12:32 AM

this might work if your lipo charger will work with out balance lead attached.check battery voltage if possible so you know where to start.

if you simply have a battery that is to too low of volts for your charger try charging it as a very small (3.6v lipo)than if it charges slightly try a 2cell setting than 3cell and so on till you get it back.

dieselmudder · 10-19-2011, 04:36 PM

well after reading several threads i think ive found my problem, 1 i unknowingly ran the battery to low, my igonrance of LiPo technology is to blame. i just thought it was a battery, run it till its dead an recharge it. and 2 venom is not a favored brand. so i guess i have to just bite the bullet an buy a new battery pack. i seriously considred switching to NiMh because of the maintenance associated with LiPo, but i think ill stick with it an be a little more attentive this time around. with that being said would anyone like to recommend a low voltage regulator/alarm/cutoff etc. so i dont have this issue again.
