Oxford OXIMISER 3X Battery Manager From  £89.99

Due to an inadvertent leaving-on of the ignition on my Africa Twin I needed to charge the Li battery. I discovered I couldn't use a std charger, nor can you jump-start or boost an Li battery equipped bike, so need a charger asap. The VisorShop had this on the shelf and I had it first thing next morning. The unit is simplicity to use: plug in, select motorcycle, and that's it. It charges, checks & maintains the battery with no other input. I used the supplied wall bracket to mount the charger to the wall. Unit seems well-made, and if it's like my other Oximiser, will last for many years. Only 2 observations I'd make: the charging lead from the unit to the bike is very short - your bike needs to be right up against the wall to reach it (a longer lead, or a 1m ext piece would be an improvement) and the mains supply lead is similarly short - I had to make up an extension for it. That aside, highly recommended.
