OptiMate Lithium 4s 0.8A 12V LiFePO4 Motorcycle Automatic Battery Charger Optimiser Maintainer

Seems smart, considering user input is 'on or off'. First round it detected and revived my battery, second round it charged it. Win! Expensive, but does the job and good for the environment keep a LiPo battery going where lead acid batteries would be trashed.

Nice compact unit that has eyelets built in so unit could be mounted to wall etc. Has a easy to understand light up display, indicating Mode plus battery charge status. Comes with handful of attachments as well as battery tethered charge lead, to attach "permanently" to car / bike battery etc, for remote charging at home. There are 2 versions I understand, however this is the lesser charging version, trickle charging at a lower rate (better for lithium batteries).

This recovered an almost wholly discharged Li ion battery and has kept it in good condition since. Arrived quickly and was unbelievably well wrapped. Owen Farrell could have drop kicked it all day without damaging it.

Does what it says on the tip, and apparently well. Probably overpriced for what it is wrt to other brands, but hey, brands matter

Basically this unit does exactly what is says on the box , just plug and play , shop around though the same unit is available at extra cost elsewhere on the net and possibly cheaper as well ! .

I've had an Optimate for at least 20 years and it's still working fine and has given great service over the years. I replaced the battery in my motorbike recently with a new fangled LiFePo one - which is a great upgrade! - so I needed to upgrade my Optimate too. Suffice to say this is just as easy to use as my original - just plug it in and let it do it's thing; charge, test, maintain = peace of mind and so far starting first time with no problems. Very pleased.

Excellent charger. Speaks quality from the moment you hold it in your hand. Brilliant combination of sophisticated programs yet so easy to use. You literally just plug it and forget it. It will look after your batteries for you. Highly recommended.

my Panigale V4s lithium ion battery went flat over winter from lack of use. This charger brought the battery back to life and stopped it from going flat again.

È riuscito a recuperare una batteria LiFePO4 che con il caricabatteria originale non veniva caricata affatto, i led spiegano bene in che stato è la carica. Ottimo prodotto, straconsigliato!

Loisirs, très beau produit conformae à la description, vendeur de confiance, à recommander

What a great deal on a product. Works just as anticipated. Used on a EarthX battery installed in a aircraft.

Easy to operate strong charger for lithium batteries...no complaints...charger and maintainer
