I’ve had 3 of these batteries break on the balance cable and register from 4s to 3s on my charger.
The batteries that have broken have all been the same GNB 1100mAh 4S
Luckily I’ve managed to “rescue” one of them but one has had to go in the bin and the other is on the bench for surgery later today.
I’m going to message Hobby RC but don’t expect much as their policy states they are only covered when dead on arrival.
Just wondered if anyone else has had the same issues?
I’ve only used the GNB 1500mAh 4S 130C version and so far touch wood I’ve not had any issues Howard. How are you securing the balance lead when the battery is on the quad? I can only assume that its getting pulled on when battery ejects in a crash or something?
That could be the issue mate, when the battery ejects it will be putting all those G forces on the leads pulling out from the straps. @DeanoG60 printed me off some balance lead clips that work a treat. You don’t need to strap them at all so no forces act on the leads when ejected. I’m at work right now but I’ll post a pic when I get home
I have quite a few of them and have yet to have a problem. All the leads are silicone’ish coated and are very flexible so they shouldn’t just crack or break.
I would check that the balance leads are not being either over-flexed, or cut by the battery’s clear shrink wrap, as that stuff is pretty stiff & sharp too sometimes. I’ll sometimes trim the clear plastic shrink wrap back a bit to allow the cables a bit more freedom to flex.
If they’re coming apart at the connector end try plugging and unplugging from the charger using the connector only, as pulling on the wires can easily pull pins out of the socket or worse pull wires out of the pins which is harder to rectify
