Hi Everyone
I have a query, We have some low voltage (24v) led light strings that run off a 24v transformer (down from 230/240v - UK).
We wanted to run them off battery packs so we bought 2 x 12v (in series) batteries to make 24v.
When we wired up the batteries the lights were duller! So we put a volt meter on the transformer a realized the output was actually around 29v!
Am I correct in thinking this will be why the lights are duller?
If so would the following work? Can I wire up 2 x 12v and 1 x 6v batteries in series to make 30v?
Would it matter that the 6v battery would have different Ah
Would the extra 1v damage the LED lights? If so is there anyway to reduce 1v using resistors etc?
Finally how would we go about recharging the 30v battery as one unit?As we do not want to split the batteries to charge them. Could we use a 24v charger?
The other option someone suggested is to use an inverter with the 24v battery packs and run the lights using the transformers that they come with but it seems daft to run and inverter off 24v to make 230v then to bring back down to 29/30v. Do these inverters drain the batteries at the same rate as whatever is plugged into the inverter or does the inverter use battery power itself when nothing is plugged into it?
Any help would be brill.
Thanks Phill
