09 bottle battery
- Thread starter friendly1uk
- Start date
It's starting to get a little bit chill in Switzerland (around freezing in the morning) and I noticed a big voltage drop with the Panasonic "09" battery.
Even only after a few km on the BBS02 500W the display shows 1 or 2 bars out of 5. If I rest the bike for a few minutes, the display goes back to 4 bars.
With child seat or heavy child trailer with 50kg of kids (total trailer over 60kg) and light hills I usually get about 30-40km per charge. Now it's down to 15km.
Is that a normal behaviour for a Panasonic cell or do I have to doubt if it's genuineness?

I'm hoping someone can help me. I opened my 09 bottle battery and found what looks like a blown capacitor.
Should I just replace it or find out what caused it I the first place?
Also, this looks like a temperature cutoff sensor. Should this be touching the fets?

What is that big hairy thing beside your caps?
Page 1 has another pic of this board. It's the 5v area.
I'm not sure about the temp sensor. I think it might be for the cells but don't reach in these circumstances. If it were for the fets I would of hoped to see it glued to them as them have made the mounting decision for us. Only real answer will be to ask bmsb who sell them. Though anything from them is still not gospel
laplaya, I would get the power on them see whats in the socket. Hopefully 5v and ground will be easy to find, leaving signal as the remaining one.

That's what the insides of those caps look like when they're not inside anymore.friendly1uk said:
Normally teh can just pops open along a prestressed area on top, and vents gas and/or fluid there. But they've glued these down and apparently covered the tops, so the only easy relief was to blow the guts out of the rubber seal on the base instead.
I can't tell from the pic, but you could try measuring from where the negative lead of the cap(s) solder to on the board, to where you *know* the battery minus connects. If there's no continuity, then try from the negative cap leads to the battery plus. If that then does have continuity, the cap(s) installed backwards, and that would be the cause of blowing up.shorza said:
Then you can feel relatively safe just replacing the caps and making sure they're installed correctly this time.

Thanks Amberwolf.
It sure did make a mess, which I have cleaned now.
The area of the board where the caps are looks like it's for the 5v USB. The small positive and negative leads coming from there go to the USB port. I haven't used it as I don't trust it.
I have since snipped the blown cap off and will see how the battery goes.
I have since noticed what looks like a blown chip.

Just guessing based on general layout and the inductor (square thing) between that blown part and hte caps, but that blown part could be a switcher chip or FET, and the cap could have been part of a filter or input to the swithcer, probably the whole area is the 5v regulator.
Dunno which part blew first or why. but if you do check where the leads had gone on the cap vs where power/ground ought to be on the board, it might tell you at least if the cap had been backwards.

Thanks for your help. I contacted bmsbattery who stated that my motor is too big for the battery and to buy a new bms.
I doubt that is what caused this. I'm hoping the damaged areas are only for the usb port.
The battery seems to be working ok so I'll pretend that there is no problem.

One of these packs has died, having done very little. It's the cheaper chinese celled version. String 2 is at zero volts. One of these packs had a slightly glowing led when switched off and I think it could of been this one. No further testing as yet.
Bugger. The customer now has my nice battery, which I have never even used. Gotta honour that warranty though.

Anyone know where I can get a controller for one of these? I don't see it on the bmsb site now, or anywhere else. They list the bms I need but not the controller and I can't get a reply from them.

Thank you.
Unfortunately there is a bit more than the $20 controller in that package. They no longer sell the controller alone though, so that has turned out to be my only option. Leaving an otherwise full kit sat doing nothing. I can't buy all that and have it bust though, it's not cost effective. I'm going to sell the kit with external controller, to someone who don't mind bits stuck all over there bike. £500 worth of pointless.
