Battery is worth the money

Purchased it for our camper. We needed to purchase a new box for it and had to redrill a few holes in the box, but the battery was worth it. We used a slow charge (trickle charge) and it took approximately three days before it was finally charged, but it works beautifully.

Love it!

I use this battery to run a CPAP while camping, it is AWESOME! 5 nights of use plus charged my phone several times and a couple other devices several times with out needing to recharge the battery! FYI you do need a charger that is rated for LiFePo batteries.
