I have two 180 Varta Sealed FLA 12v batteries in my stable block Which are charged by a 240kw solar panel on the roof to provide lighting to the stables.
The batteries are in the feed room and we recently boxed them in with ply wood to prevent theft as they are obviously expensive. There is a Victron charge controller just above and the batteries are only going to be charging in daylight.
Question is about adequate ventilation- the box is surrounding the batteries and has a lockable flap down lid.
The only ventilation is down one side about 1 inch wide gap x 1ft where the cables feed out of ; is this enough ventilation ?
Having read about batteries am quite confused about needs now and do not want my horses to go up in smoke! thanks for your help.
