Small and cheap but does a great job in controlling charge and is programmable as to the cut-off voltage etc, which makes it adaptable to different installations. We use it outdoors in a battery box to control a solar cell powering an electric fence. It's been brilliant and reliable, plust the USB ports are a useful bonus. Highky recommend, this is a great price.

I bought two of these and within days of using them they BOTH developed a dangerous fault. They were outputting over 15.5 Volts!! (even when set to output 13.8V !!!). One of them wrecked my leisure battery and I have had to replace it at a cost of £91. The other was used in a friends shed, which is right next to his house. The fire that could have resulted might have burnt his house down!! Overcharging batteries like this can cause them to explode, showering hot Sulphuric Acid around. A fire could easily result, and that could spread to a house, surrounding camper vans, caravans or tents and people could DIE. I ended up buying two replacements that were made in the UK. They work fine. p.s. = my multi-meter has been checked and is accurate.

I bought 2 units, 1 unit to use with a lead acid battery and a solar panel supplying several strings of conservatory led lamps which all work fine. 2nd unit is to be used to be used with a solar panel to maintain a canal boat lead acid main battery.
