Looks like the tray the battery sits on has a longer raised lip near the bottom where the battery power connects?

How much more range/power does this battery give you compared to the standard one? Don't want to carry a second battery around if this one can do the trick.

The 48v Dolphin is a direct replacement,

Range on an e-bike is proportional to the AH rating of the battery. The Luna whale is 17.5AH, which is 52% more than the standard 11.5AH radrover. So figure 50% more range. If you got 30 miles before, now you got 45, etc. If you're a battery miser and got 40, that bigger battery promises 60.

Looking at the 13.5AH vs 11.5AH Dolphins, there's a 17% increase. Same math.

Actual mileage of course depends on average speed, wind, rider weight, and how much you pedal, but assume that doesn't change much, and you can simplify it to the AH rating of the battery.

.

Plus, your Radrover will have better acceleration, torque, and top-speed. I did this to mine the first month and the controller and motor handles the increased voltage fine. The stock system is very overbuilt for the amperage and voltage that RPB chose to run through the system.

The 52v 13.5ah looks like a more powerful battery pack AND has a cheaper price; which, doesn't make sense to pay more for less with the 48v version? I'm thinking it might be a typo on the website for the 52v version.

MrGold, 435 is for the 11.5ah the 52v 13.5ah is 465. I just ordered one last Sunday. It should be here next Tuesday.

Thanks for the clear up!

I'm hoping the battery upgrade will fit exactly like the old battery. I added a Luna Cycle cover; but, that doesn't look like it takes up too much additional space with the old battery.

I would like to hear about any performance and range boost with the new battery once you make your rounds with it. We had a wind storm move in yesterday with 25 mph head winds and 30-35 mph gust for my +6 mile ride home (and +500 feet in elevation gain). I was 100% charged at work and arrived home at 2 bars. The Radrover was between 500-740 watts the whole time. Might not of made it home if I lived +10 miles out.

A little extra range and power wouldn't hurt.
