  • Short bolt posts, but great battery otherwise.
Style: 12V 100Ah 1 Pack
Received this battery in a timely manner. Well packed and in great condition. Seems to be holding a charge for a long time while being used in an RV. My only complaint is you have to use a bolt for the connection post, and it was extremely short. Since I'm connecting two in parallel, I need to have two connections on two of the posts. The bolt was so short, I had to buy four bolts (M8 x 16mm), eight washers (doubled all of the posts because one made the posts with only one connection extend too much), and four lock washers - all stainless steel. Ran about $12. After getting these set up, everything worked great. Didn't want to give 4 stars because this was an easy fix, and the batteries were a great value all the way around. Just wish they had actual posts to screw the nut on instead of screwing in a bolt. ... show more

  • Fast delivery and well packaged
Style: 12V 100Ah 1 Pack
I received the battery in individual boxes with foam padding all around. I read the instruction manual that came with them. It says they ship with only 50% state of charge (soc), so I connect each of them up to my 15A smart charger and set it to Lifepo4 type battery. The charger output varied between 13-14A and the voltage slowly climbed from13.13v to 14.6 when the charger shut down. The first battery took 3 hours and 46 minutes to charge which equates roughly to about 47 Ah. The second battery charged for 3 hours and 38 minutes or about 46 Ah. This gives me confidence in the 100 Ah rating. Time and usage will tell of the quality and durability, so I’ll update this post later. I plan to use these as trolling batteries in my boat. They’ll be connected in series and see a max current draw of 42A. I like to fish from sun up to sun set with intermittent trolling motor usage and duty cycle, so they will get a work out this season. The batteries look to be of high quality, the bolts are a little short (1/2”) and they give you an extra set of the same length. It would have been nice if the extra set was a 1/4” longer. Note the bolts appear to be made of stainless steel, which is a nice surprise given the trolling motor application. The AGM SLA batteries I’m replacing lasted 8 years, so I’m hoping these will last at least that long. Update 7/21/24: I've used these batteries extensively over the past couple of months. They work great. After a full day of hard use the voltage never dipped below 25V (12.5v each in series). I've drained them down as far as 75% depth of discharge (DoD) and with the 6 amp/bank on-board charger they recharge in about 12 and a half hours. I may upgrade to a 10A/bank on-board charger to reduce the charge time, but so far I'm very happy with the battery performance. Note: I try to charge the batteries fully just before use and keep them at ~50% SoC when storing them. The lower voltage during storage prolongs the life of Lithium batteries (unlike lead acid, which should be stored at full potential). ... show more

  • More power!
Style: 12V 100Ah 1 Pack
Bought 4 of these for my 48 volt Club Car. Been watching the prices and got them for $150 each on Prime Day. My 6 - 8 volt lead acids were 4.5 years old and not keeping up. Easy to replace. Lots more room in the battery compartment and a whole lot less weight. Old set was 400 lbs. and these are just short of 100 lbs. Much better acceleration and higher top speed also. Drove for 2 weekends and still at 80% charge. Hope they last the 10 years they say they will!! Thanks Again, The Allmans ... show more

  • so far, so good
Style: 12V 100Ah 1 Pack
I have been very pleased that the low temperature is working very well as I have been faced with 22° temps. They are definitely holding their charge in face of multiple nights of cold weather. I've not had them long enough to get set up to keep them warm, but I'm in the process of doing so. I have been pleased with the overall performance of the batteries. ... show more

  • Great battery and at a bargain price
Style: 12V 100Ah 1 Pack
I bought this because of a recommendation from Will Prowse (you can find him online) and he was 100% correct. The battery seems to be a good quality, and I'm looking forward to many years of service!

  • Reasonably priced and high performance
Style: 12V 100Ah 1 Pack
The switch to a lithium battery in my small camper has been a huge improvement. With the old lead acid battery, you had to always make sure the charge never went below 20% as it would very likely damage or even “kill” the battery. The lithium battery is NOT effected even if the battery drops to zero charge. Also the physical size of the battery is the same as the old one so it fits perfectly in the battery box. Other benefits are that the battery weight is 1/3 that of the lead acid batteries and cost is only slightly more. One cautionary note for cold weather campers. When the weather drops below freezing, the lithium battery will cease to charge until battery temperature gets back up to 32 degrees. This is not to say that the battery does not function, it simply won’t recharge. The only unknown is “What will be the longevity of the new battery?” The company Claims up to a 10 year life but even if it lasts half that time, it will be well worth the investment. ... show more

  • A great lightweight battery
Style: 12V 100Ah 1 Pack
I use this battery to power my dump trailer, but I disconnect it and take it inside when not in use. Since it's not made of lead, it's much easier to carry. It also has more power than the old lead battery so I can make 5 dumps instead of just 3.
