The Cheapest Battery Shop in Australia

"I have bought two LiFePo4 batteries through big wei and I have to say, they are wonderful! Both the 12v 200ah and 12v 100ah are great performers in their applications running seperate caravans on off grid solar. If you are looking for true performance LiFePo4 as advertised then that is what Big Wei is offering and at an affordable rate. Any problems and their customer support staff are right on it and champions at resolving any issues that may arise. I would recommend anyone who is thinking of going lithium to go get it through these guys. "

"Love this 200 AH battery! Bought myself a camper van so needed to sort myself with a good battery. Did alot of research on AGM(deep cycle) vs Lithium, went with Lithium as needed the less weight. I use a Epever MPPT solar charger, 200W fixed solar and just ordered a 250W portable solar so i can park in shade and still charge! There is alot of people out there scamming selling Lithium batteries, extreme batteries being one, i bought a 120 AH for $500 and ended up being only 44AH. Now Big Wei 200 AH what a dream! Did some testing, first test ran a 50 L 50 W 12v fridge for 12 hours, Battery Voltage was 13.2 and 12 hours later still at 13.2 and fridge is nice and cold!! Test 2 , Ran microwave for 30 mins, fridge on over 48 hours, LED lights about 4 hours (15W) , Fans for 1 hours (15W) , TV and Nintendo switch for 2 hours, Apple TV with inverter on to power it for 3 hours. Voltage went from 13.2 to 12.9 then settled to 13v. Both days were super cloudy and got most 40W from the sun for maybe 3 hours. Battery wasn't even charged in between test 1 and 2. Unfortunately i don't have a battery monitor (through a shunt) yet to test the remaining Amp hours, but you get a good idea with Voltage. So couldn't do accurate testing but i hope this real life test gives you an idea. Highly recommend this battery, lovely staff available over live chat anytime and always answer their phone! They mention on there website there A grade lithium cells. And are used in electric cars!! There are so many fake lithium batteries out there, buy one from here instead wont disappoint !"

"Hey, Big Wei! Thank you to the owner and staff. You guys rock! Very friendly and accommodating. I know very little about Lithium Iron LiFepo4 deep cycle batteries and without you guys I wouldn't have bought this amazing 100AH Lithium iron and saved $$$. Didn't know there is this great product out there perfect for my boat. Cheers, mate! See you next time."

"I purchased a BWB 12V 100AH Lithium Iron LiFePO4 Deep Cycle Battery, about a week ago for my 12 foot Titan kayak, very heavy. I have a 24lb watersnake trolling motor. I used the motor for about 3.5 to 4 hours almost continuously on the fastest setting and the voltage dropped from 13.2 to 13.0. I was impressed for a 10kg battery that i can pick up with one hand. Not sure how much was left but i have read the motor draws 20amps per hour."

“Helpful staff, awesome product and service! I was after a replacement battery for the Bravo BTP12 high pressure electric pump for inflatable kayak. The battery is extremely hard to source in Australia. The staff in Big Wei Battery offered great help, adapted their new 12v 7ah battery with the connectors from mine so that it works flawlessly with the pump. The battery was only $22 and they didn’t charge a cent for the service! I was so impressed and wish all the best with this terrific business!”

“Got a great deal on a battery (plus got a fair discount for trading in my old one). They took care to fit the new battery and did all the testing after fitting A great experience and will go again when I need a new battery”

“Very friendly staff and affordable pricing! 谢谢!”
