Yes, most cells Yes, most cells are slightly bloated, in common with the other 20 cells I currently have... BMS cut offs 3.65 max, 2.6 min. Controller same as I use on my primary cabin not far away. Indicates 30 to 40 volts input to battery and 5.9 amps max at midday. That's the output to...

Interesting theory, a bit too Agatha Christie like to me, as these cells have been in their own box since new, about six months ago. And situated in a remote cabin in the middle of North Borneo ! But accidents do happen of course and there certainly are a lot of curious creatures here (even...

The company, Global power Co LT Store of China has agreed to send a free replacement.

You're right it does seem to have imploded inwards, according to the blue Alu film... But sits in its own plastic box (with lid !) So I can't see how anything could get to it whilst in use ... I took another (macro) photo. The transparent top covering was pierced in a thin oval shape. I have...

Just to clarify - I added another 100 watt solar panel recently and moved the array into full all day sun because it previously only charged at about 1 amp for 2 hours a day... So the SCC (MPPT) shows 30+ volts (2 panels in series) coming in and charge at 5.9 amps max. out to the battery pack...

Strange then that there has been no oxidisation on the other 27 similar batteries on similar set up (same SCC but running at 24 volts and up to 20 amps) in our main nearby cabin, which has been running solar for 3 years now...

Thanks for the info - no one else seems to have seen or heard of this...I certainly was not made aware this could happen.

Always use charge controllers. Been in this business for 20 years, before they (DIY) used SCCs !

There is a solar controller. Used in a previous set up and reliable enough I think.

your profile looks interesting (blank/not available) and you've been on here a whole year ...what an old timer !

Charging with two 100 watt panels (just moved into full sun) and giving 30 to 40 volts and a maximum of 5.9 amps at midday. Most of the cells are slightly bloated.

Very interesting and informative,thank you. But there are some signs of chemical outside...not much, but it a high humidity environment here.

But some signs of chemical powder on the nearest terminal.

No melting or signs of heat.

Actually an 80 year old and don't be so rude - we do our best.
