  • Makes our golf car go noticeably faster
Size: 36V 100Ah
Our golf car goes noticeably faster without any modification. We used to average 12 mpg now 15/16 mpg. It may not seem like much but you notice the difference. Easier to charge. Alot smaller than the 6 large batteries and less weight. No maintenance checking the water. Very easy to assemble. We have had it almost a year with no problems. ... show more

  • Seems like a good battery buy I'm skeptical of any real warranty
Size: 36V 100Ah
Purchased a 36V 100Ah battery and installed it in an old Club Car DS golf cart. Battery was packaged well and came with a charger that is a bit flimsy but it has a cooling fan. Took about 12 hours on the initial charge to get the green light on the charger. (think its a 5 amp charger). Battery charged up to its max voltage. No big deal wiring it up in the cart. 300 pounds lighter now and the cart wants to wheelie off the start! Better top end speed as well. There was no warranty included and if you look closely , it states on Amazon that you need to retain the proof of purchase. Kicker is if this company leaves Amazon prior to the 5 years you have 6 months on your warranty, and thats it. Factor that into your purchase decision. I chose to keep the battery and hope for the best. Don't expect much of anything regarding the operation or specs to come with the battery or charger. There is just a useless little two page thing half Chinese half English. Read up on how to care for and properly charge and discharge this type of battery with your own on-line research. Remember that you'll need a step down voltage converter to run any lighting or a radio on your cart. As a seasonal user I was going to go with AGM batteries for maintenance reasons and they were more expensive than this lithium battery .I will update this review after I've put some miles on the battery. Update: I drove the cart quite a bit on level pavement since installation of new battery. I wish I could tell you how many miles I put on it but I estimate 15 -20 miles and a lot of short trips over a 10 day period or so. Battery percentage and voltage stayed high for quite a while but when it got below 50% under load, battery percentage and voltage started to fall off very rapidly. I went from 50% battery (under load) to 0-10% / 32V in 2 miles. I was worried about making it home. Got back and no load showed 10% and 32V. I did not intended to drain the battery that much before charging. Also put on a step down converter to get 12 volts, but did not use the lights that are powered by the 12 Volts during this time. I don't know how much power the converter draws when not in use. Cant imaging much if any. ... show more

  • I can't believe I lugged around a 90 lb lead acid battery for so long
Size: 12V 100Ah-B
I have been debating moving to a lighter battery for my canoe for some time. I have used a nut-buster, 90lb marine deep cycle battery for years to power my Minn Kota 30. Lugging that monster I wonder why I never got a hernia. I did use a smaller deep cycle battery, but I ran out of power twice and had to paddle to get to the take-out. This year I decided to go light, to go Lithium. One thing I did not count on was the sticker shock. After two weeks of searching for good reviews AND a good price I settled on a LiFePO4 Battery 100Ah 12V 1280Wh Deep Cycle from SCREMOWER. I wanted at least 100Ah, with marine terminals, it came with an included 10A charger, and I would get it within five days. I received an e-mail stating item had shipped, so I started tracking FEDEX, but FEDEX showed they had not received the item yet and five days now stretched to seven days. Fortunately SCREMOWER has decent customer service and they responded to my query about delivery. They acknowledged they erred and apologized for the delay. The battery and charger arrived on Monday and I promptly charged the battery. Then I noticed the charger was only 7A. I contacted SCREMOWER and they told me the battery now ships with a 7A charger which is yields better battery life, and the charger is considered a gift. On the second day when I charged the battery, the charger started whining and making noise. The mini muffin fan was defective and was headed for failure. Another e-mail to SCREMOWER described the issue and after several e-mail exchanges SCREMOWER agreed to send me a replacement. I was informed that since the charger was a "gift" there was no warranty, but they would send me a replacement as part of "customer satisfaction". So far the battery has performed with issue. We tested it on the Saco river in Maine, taking care not to drain the battery. We need not have worried. We cruised all day, up river, down river, into a strong headwind, and still had ample power to spare. And talk about light - a mere 27lbs. What a pleasure to not have to strain just to carry the battery. I still have more testing to do now that boating season is about over. I may use the battery as a pellet stove backup supply, but that depends on what else is needed to connect to out Harman Advance Pellet Stove (converter, etc.). The battery also works well with my 2000 lb winch. ... show more
