I've added another paragraph that hopefully covers most of that (well, I nicked it from a trustworthy guide to lipo safety! Big Grin ) There might be a tad too much jargon in there for new LiPo users though! Facepalm Big Grin

Is that the 4.2v or 8.4v DAP? The 4.2v version doesn't need to be balance charged, for the reasons that Pipeman mentioned. The 8.4v DAP connects to an external balance charger: The LiPo pack is charged while it's inside the mod, but the charging happens through an insulated balance charge port, which means that there's no risk of the connector shorting out against anything.

RE: LiPo battery safety:
In the DAP the batteries are kept nice and snug in the mod with dedicated wiring to the charge ports, whether the 4.2V or the 8.4V. The battery in the 8.4V can only be removed by de-soldering the charge leads from the connector.

For many of my own personal mods I charge with the LiPo in-situ in the mod. I have either made a dock or a special charge lead for the purpose.

I guess they recommend not charging in-situ in case the LiPo catches fire whilst charging so you don't lose the mod too, but if you follow the rest of the advice (especially the balancing and 1C charge rate) and the battery is securely held in place so it can't get damaged the chances of it catching fire are very remote.

It's probably just advice designed to make charging stupid-proof. If I very stupidly set my charger to 4S and 10A when I charged my DAP, bad things could happen to both the LiPo pack and the DAP!* HeHe!

Your charger would tell you that you had the wrong voltage and beep at you. Chargers are designed with you in mind HeHe!

You might not believe it, but I'm a lot better with this stuff than I used to be. The first time I used a balance charger, I was surprised to hear that it made a strange whirring sound. I asked Poo what it was and he replied "it's going to explode! Rip the plug out of the socket NOW!" I almost shat myself and frantically ran to the charger to do as he said. It wasn't until quite a while later that he explained that it was just the fan. Facepalm HeHe!

There's no need to dispose of your battery. LiPos shouldn't be stored at full charge or 'topped up' regularly over long periods of time, but a couple of days won't hurt them. In future, just use the mod until the battery is at the storage charge level (about 3.8v per cell, so about 11.4v for a 3S LiPo) before charging it. Smiling
