This is a drop in replacement for your Lead-acid battery and includes a 4 amp fast charger in the package. 

It can be placed in applications where lead acid batteries are normally used -

Reviewer: Mark Sanders from Tenbury Wells   5 Stars

Bought one of these batteries a couple of years ago, and it has performed absolutely faultlessly ever since in its application (powering the avionics in a glider). It give loads more run time than the equivalent SLA battery; has a better cycle life, and comes in at about one third the weight - what's not to like!? Case compatible with NP7/12 so it's a perfect drop in replacement. Comes with a charger too.

Only gripe is they have been out of stock for well over a year now - can someone from Liberty please tell me why that should be - because you could sell loads of these to glider pilots!!?
