3rd revision

1st battery was fine and gave 60~miles. I bought a spare and it was 3lbs~ lighter. First full charge full discharge was 38 miles ~. Yet 3rd full charge/discharge gave 60~ miles. Basically same as the larger first battery. So FYI these newer smaller batteries supply same as the first one did. I’m in Florida and flat land. 16” tire hub motor @ 300 watts. That is my experience. Very happy with both batteries. Just testing them out. Highly recommend them.

Modified version

Ronald Manzi here. Just used second battery went 38 miles. This second battery is slightly smaller than the first battery and 3.25 lbs lighter. So… range was less. I can only guess perhaps new product being refined. I was just testing it. No problems with the first battery. Happy camper.

Just got the battery. Super easy to wire up. Much more power and battery life than the original Lead batteries. Very happy with it. I have it wired to a 48V 1000w motor MotoTec mud monster go cart. I am 200 lbs and it pulls me around in grass and hills plenty of power. Lasts for hours. Don’t hesitate just buy.

So far so good

This is my second purchase as a backup battery. (Just in case, you’ll grow dependent on the extended travel ability) The first one gets me and my recumbent bike with a 300 watt motor a good 50 miles. Front hub motor on a 16” wheel. The speed I get is about 15 mph. It takes about 10 hours for full charge. I’ve charged 70 cycles so far. They recommend fully discharging and fully charging first few cycles. Very happy, and the battery does not ever get hot.

Very good, best battery ever lasts 7 hours of continuous use

This is the best battery I’ve ever bought
