Gentrax Lithium Battery –Battery was delivered very quickly and running the fridge in the back of the Ute well. No issues and will be considering a couple of the 200ah for our caravan. Great Product at a fantastic price.

No dramas here
I haven't had a chance to use it but I believe it will work as it supposed to. It got delivered quickly and looks solid. Bit bigger than the normal battery but It fits in a large battery box without any problem.
Stuart
Would purchase again
Purchased a 200 amp hour gentrax lithium battery to run a fridge and eletric trolling motor in my boat. So far very happy with it. I noticed that it held its 100% charge even after not in use for 1 month.

They work just fine. Recommended
Len K
ok so far, haven't really tested it yet
Pamela K
Seems to hold charge. I haven't had them installed
Seems to hold charge. I haven't had them installed yet so I don't really know how efficient they are or how they will age but the price was good and the weight is much better than the old AGM battery.
Jeff Cron
Good price and arrived promptly.
Arrived promptly, good communications. Have not fully tested yet but looks good.
Anthony
Great battery - works as promised! Quick delivery
Bought this to compliment an off-grid setup on a farm. Tested and it ran my kitchen fridge at home for 2 days and was still showing 13.3v - definitely worth buying.
They even followed up to make sure I was happy with the product - good work Gentrax.

Great Battery- Great Price
The Gentrax 200ah lithium batteries are a direct replacement for the original 100ah batteries in my caravan, doubling my capacity for little extra space.

Excellent value 2nd battery for 4WD camper. Speedy delivery to our front door. Too soon to speak to longevity but it is very light and seems to be good quality.
