    Radwagon Cargo...

    Posted by Eric Amundson on Feb 20th 2024

    This battery fits like a glove behind the seatpost on a Rad Power Radwagon. It nestles right into the frame nicely. Best part is the two wire RadPower/XT90 adapter wire enabling plug, and play with the Rad Power wiring harness. Another bonus was the Area13 dual battery adapter I used to connect the two Rad Power batteries I already had on the bike. If the Rad Power/ XT90 battery cradles were in stock I would have bought two to make the project 100% plug and play. I now have three batteries on my cargo bike.

    Great Battery, but I don’t like the...

    Posted by David Welch on Aug 10th 2023

    This is a great battery - 52 volts and 20 ah. I got it for my 2018 Rad Rover, that I previously upgrade with the Area 13 controller and the true 750 watt motor. After upgrading the controller and motor, I had the power I wanted, but my range was cut, so I decided to do the battery too. Since I like Area 13 products, I bought this 52 volt battery from them. It’s a great battery, but I didn’t like the fit or the look on my Rad Rover. Area 13 understood my concerns and accepted the return.

    52V 20AH Triangle Lithium Battery

    Posted by David Welch on Aug 3rd 2023

    I’m sure this is a great battery for my Rad Rover, but it is large and the Velcro bag just doesn’t look good to me when mounted on the bike. I have decided to return it and continue my search for another 52V battery. Excellent service from Area 13 as usual.

    Absolutely insane range

    Posted by Sam keeley on Feb 26th 2023

    Mine charges to 58.7 and a 35 mile ride only drops to 51 and that's in the Pennsylvania hills seems cutoff is around 41 I dont like math but the range with the upgrade in mostly 2 setting will erase range anxiety forever .

    Posted by Mark on Feb 26th 2023

    Was a great upgrade for my RadRover bike, love it so much I got a second one in parallel in-my bike trunk, now I can travel the 40 miles round-trip to go see my grandson or friends in another town without having the get stranded worries.
