Pila IBC charger observation/question

[Kremer]

Hello,
I recently purchased a Pila IBC charger and am using it on 18650's (with the lid open). I noticed that when charging one cell that everything stays nice and cool to the touch. But when I have two cells in there the charger gets quite warm and since the cells are on top they get warm also. I have not put a thermometer on the cells but I'd estimate warm to the touch = 95F-105F or so in a 65F room.

Is this anything to even be slightly concerned about, or am I just being a little hypersensitive to heat=bad on li-ion cells ?

While I only charge Pila 300P cells in my IBC, it's completely normal for it to get slightly warm. If it's excessively hot to the touch and causes pain, then that's cause for concern; but that doesn't sound like the case.

Hello Kremer,

Mine does the same...

when I try to charge AW 18650 with this charger, the batteries plastic coating doe not allow the (-) arm to touch the (-) end of the battery. Do you think triming the plastic to make contact is ok or just find a thin spacer(copper, aluminum, plain old steel. which is best?) to make contact.

Thanks

Thanks Tom, I guess this is normal then.

Headlight: maybe try tweaking the spring tab a little or see if you could clamp something on the tab? a split lead fishing weight pops immediately into my mind, but I wouldn't use lead. A tiny solder blob would do the trick also, but it wouldn't be too reversible.

EDIT: you could also use a little conductive magnet, or a tight wad of foil, but that would become a PITA pretty quick I'd think.

I would not trim any plastic off of the batteries. The plastic in many cases holds things together. I can't picture exactly what your problem is although it sounds straight forward. Can you post a picture?

trim the plastic on the charger, get the dremmel ethel, another mod.

the(-) tab pivots from the side of the battery(when laying flat, so when the battery is inserted it pivots towards the (-) end and hits the plastic, preventing it from touching metal. I finally fixed it by clamping a cut up female spade connector on the end of the tab. Works fine now
