Hi Guys,

Just after ideas on a small issue that I have with my charger..

When I charge my lipos or life batteries on charge/balance mode, with all the right info for battery types correct, and balance board connected..It starts to charge fine, however when the charger gets close to finishing, the charger stops, and then beeps constantly, and a message on charger screen says, BALANCER VOLTAGE TOO HIGH?, this always happens when I am using the balancing mode, if I don't balance the batteries, then it will charge to peak, no problems....And to stop the beeping I just push the enter button, and then start it again, most times it will start beeping again, stating the same screen message, and after a couple of times of doing this it will eventually end the charging/balancing mode will stop..

so just wondering if anyone else has had this issue with this charger, or something similar, or I may have to look at getting it looked at, possible dry solder joint or something...cheers...

Sounds like you have a bad cell in the battery, i had a TX 3 cell that did the exact same thing. One cell would read high while charging, tried on a stand alone balancer, it'd balance out but as soon as i'd try charging it i'd get the same cell reading way high again. If you have a volt meter hook it to the negative lead then read across each cell one at a time on the balance plug, that will let you see if it's the pack or the charger.

Cheers for ur thoughts...but as I said this issue only happens when I am balancing the batteries, so I have 4x life 6.6volt/1700mah rx and 2x lipo 2100mah/14.8volt batteries, if I just charge these batteries without balancing, the beeping issue does not occur, only when I balance them is when it happens, so I am thinking it may be a charger issue, not the batteries....

I'd question whether the internal balancer went out or not. I had a Hitec X4 charger go out on one of the balance ports. It would never reach peak voltage. Sent it in and they fixed it. I'd check your battery with a good volt meter after a balance cycle to see where the voltage actually is. Most companies will test your charger free of charge, aside from you having to pay to ship to them.

yeah definitely think it`s the charger, I have one of those battery check things that you plug the balance lead in to to check the voltage per cell or individually, cheers for your thoughts...

with SJ units, they're generally pretty ok but occasionally gotta watchout for:-

1, dry joints on PCB... some go bad after bumping your charger around field/track
for a few years. Could be worth opening up case and reflowing all the joints.

2, you may have a dodgy balance tap board, if you're still using the stock original.
Could be a bad pin or wire, or solder joint has gone dry - take a close look.
(If a middle wire loses contact then its neighbour will suddenly read double voltage.)

You can buy spares but I also find it very short & stressful for the wires when
you need to pull it all the time, so i like to replace the plug-in board totally with a
custom-made cable. The plugs are common Molex connectors, i like to wire 1
for each type of battery and be long enough to reach where i want the battery to be.
