Great company and Great product!!
Battery works as intended. And has a nice status indicator on it. But the real winner of the show is the company. After reaching out to them letting them know I didn't receive the batteries (for a wheelchair for a handicapped family member). Even though the shipping company posted a picture of my yard there was no package in the picture. Needless to say I'm sure the shipping company delivered it to the wrong address or it was stolen. This company made it more than right by shipping out a new set of batteries and even had me verify the correct battery was being shipped with the wheelchair owners manual. And went further and verified the BMS had enough watts to handle the motors load. I got the batteries and they provide very impressive response on the wheelchair all the way until the the batteries need to be recharged. Unlike the old school 40 lb each lead acid battery that just slows down as batteries get to the point of recharge. Both of the batteries is about 25 lbs or so and that's alot of weight saving! Thanks and I would definitely purchase from this company again!

Good quality but did not fully charge to 15AH for me
I open them and provided pictures and charge results. Quick Facts. - Battery only charged to 14AH out of 15AH from fully discharged. Does not charge to the rated 15AH. I used a charger with Lithium ion charging capability. - Cylinder batteries have no markings of make or model or anything. - Double wrap in plastics, seems durable and protective of the battery cells. - Voltage monitor on the battery is not reliable; more of a suggestion than anything. I provided pictures of charging test and tear down of battery.

Awesome battery for the price.
Awesome battery for the price. On sale on a regular basis. I have purchased two. I really like the voltage indicator built into the battery itself. It fits perfectly into those cheap small ammo boxes so I will use that to build a multi port power box.

Good to go, time will tell if it maintains charge.
So far so good. Ive only used it a few times but it holds a charge very well. The digital readout is bright and readable in darkness

I ordered this battery mostly for powering my tyre air compressor. Once I'd fitted a cheap adapter to the terminals for the cigar lighter connection we were up and running. Now you do need a suitable charger for this battery as the charge voltage is higher than that needed for a lead acid battery. The battery is quite small and as such not very powerful but for smaller jobs it's jus the ticket and being small it fits almost anywhere. For the price, and for something that will outlast a lead acid battery more than 10 times you can't really go wrong for the value. It will function like any other 12v battery, but will last longer.
