Haven’t had it long enough to say much other than it’s pretty simple so far.
Charging it now.
Love the battery. I would order other things from them. Fast delivery. I give them 5 stars.
Super smooth ordering process from Weize website and received a discount for Amazon Prime days. Price for 4 6V AGM batteries was competitive to the Flooded Lead Acid (FLA) units I wanted to replace in my 2008 Newmar Dutch Star 4304. I definitely wanted to get away from the maintenance aspect of the FLA’s so it was a no-brainer. Shipping was fast and each battery arrived in separate packaging that was done very well to protect the contents from damage. Install went well, changed my Magnum Inverter settings to AGM and all seems well. Time will tell on longevity but initially very satisfied and impressed.
Battery arrived in perfect condition and fully charged. Quick shipping and good communications with WEIZE as to when shipped and expected arrival.
Batteries, (2), are what I needed. Plug and play. Only downside was shipping stated one to three days shipping in reality took seven and the protective-colored caps for the posts are missing.
The lithium battery conversion kit is very easy to install. It took me longer to remove the 6 acid batteries and prep the battery tray than anything else in the conversion.
The cart is noticeably lighter and faster and no longer requires monthly battery maintenance. Very pleased with the product and was able to save $1800. by installing myself.
My U Force 1000 takes a very expensive "super duty" battery. I didn't even check with CF Moto because the original only lasted 2 years! Some of the replacements were over $200. Weize had the compatible battery for around $70! I bought it, it arrived several days early, worked as expected! Time will tell, but pleased so far.
Product was shipped quickly, very easy to install, and has proven to be a worthwhile investment with increased speed and hill climbing ability. I did not realize and forgot to ask about a step down inverter of which this kit did not include, so I had to configure my own set up for lights, etc. it would have been nice if it was included.
WEIZE BCI Group 31M Dual Purpose AGM Battery, 240RC 825CCA 12V 110AH Starter & Deep Cycle Sealed Marine & RV Battery
I've ordered 4 ATV batteries now from Weize. I did have a small problem with 1 battery, I contacted customer service and did receive a full refund with no questions asked. Coming up on a year for the oldest one, seem like good value for the money. I'll continue buying my ATV batteries from Weize.
Great experience. I will definitely use them again.
Great battery; seems to work fine. Can't comment on longevity. Very well packed. Would be a 5 star of review, but minus one star for having no way to bolt it down. It's a golf cart battery; should have ears on the case for bolting down.
Great package
Easy to order and fast shipping. Battery worked great until it got wet and must have shorted out.
Weize YTX20L-BS Lithium Motorcycle Battery, 12V 8AH 600A Group 20 LiFePO4 Powersport Battery
I have a 1991 Western 100 Series (EZGO Marathon), which has limited space for a full-size lithium battery without modifying the battery compartment. These batteries fit perfectly into the original battery trays designed for the lead-acid batteries, making installation simple. I connected two 36V 45Ah batteries in parallel, and they’ve performed flawlessly so far. The cart climbs hills with ease, and I’m seeing speeds of 20 mph. Even under these conditions, the system has never drawn more than 120 amps, which has been impressive. Overall, these batteries are an excellent option for anyone looking to convert to lithium, especially owners of older golf carts who want a true drop-in replacement that fits the factory battery trays without any modifications.
So far the battery is great. It has a one year warranty, most of the top brand batteries have a 6 month warranty. Quick shipping and solid packing.
Great battery! Perfect fit for my Mini Cooper. Arrived on time and in superior packaging plus it was 100% fully charged!. I will be purchasing another battery for my Volvo.
Purchased to replace eight 6 volt lead acid batteries. Installation was fairly straightforward. Battery fits in the space that three of the old battery’s occupied. Seems to work very well. Glad I upgraded.
Charging. Have yet to use them
I been with Weize for years. I first bought dual AGM Group 31 batteries for my 4runner and winch and stereo. Ran them in parallel. Mega power. good quality. Now i wanted to reduce weight so I bought dual Purpose 105ah LiFePO4 batteries. Charged each one to 99% let them rest. charged them again to match voltage within 1mv. hooked them, up in parallel with no loads and let them sit for a day and half. everything was perfectly balanced to almost 0mv which was amazin.
These LiFePO4 batteries make my stereo play SO MUCH cleaner. The difference is insane!
The difference between voltage on AGM verses LiFePO4 is very noticeable The winch operates even better too. You get voltage sag and drop with AGM even in parallel banks. With LiFePO4 you get none of that.
however, i ran into a rookie issue that you should not repeat.
DO NOT CHARGE balanced parallel batteries to 100% like i did. Everything before this was balanced when discharging and charging as long as the BMS over voltage didnt trigger at 100% which each battery charges to 100% at different times due to slight capacity variations between the 2 batteries cell packs. Its a known thing that i didnt know.
I learned in days to only charge 80% to 99%. Most winch users report charging to 80% with voltage diodes or mods that dont push 14.6. You must charge at a voltage lower than its individual rating.
I was told to charge till the batteries reach 13.8volts and youll be somewhere at 80%. An unbalance came when one battery reached 100% at 14.1 volts and the other kept going to 14.5 volts!!! Then I learned people specifically dont charge banks to 100% due to this BMS trigger. To overcome this issue you need a programmable absorption voltage charger thats dc to dc like the Victron Orion XS 50 amp charger. Program the bulk, the absorption and float to whatever voltage you want. I wish Weize made their own.
overall after learning the world of lifepo4 batteries, as long as you can afford the right charger to use like the Orion XS, its a worlds difference in power delivery.
