So I decided to go for a 52v upgrade on my Sondors Thin using the Luna Cycles 52V TRIANGLE PANASONIC GA 18650 14AH HIGH POWER AND LONG RANGE battery. I carefully measured and I thought I could just barely get it in to my Sondors Thin if I took out the bumpers for the stock battery and some of the cable guides. I got the battery and even after looking it I thought it would work (see attached photos). I used a Dremel to take out the bumpers that were in there and most of the cable guides in the top right. The battery looks like it was made for the box, dimensionally it fits like a glove, but (and I knew this was going to be the tough part) the hard box on the Thin just won't quite close even after my modes. I don't think I'm close enough to quite get it there either.
I really like the look of the hard box case on the Thin, so I'm trying to figure out it:
Is there some alternative idea to getting this thing to work in the stock box. I'd thought maybe there's some way to modify the hinges... or even cutting off the outer rubber on the battery might save a few mm. Any ideas folks? That's why I'm posting on the forum. Is there another form of hard box, maybe from the non-Thin Sondors, that might fit in it? Is there something dumb I'm just not thinking of here? I guess the final option is just remove the box and put in a soft triangle bag (such as the Luna Cycles one). Does anyone have any experience putts one of those on the Thin? And once I do that I might as well get an even bigger 52v battery, right? I've also got photos of it compared to the ElctroBikeWorld LT48.
Appreciate any input anyone has. Thanks!

Sondors Red 60V 750Watts 7 Speeds
The Sondors Red fat bike 60V 17.5ah battery, 35a controller, 750Watts motor, 7 speeds bike is now built and let's just say this is one fast bike.
I ended up using the stock wheels, I may still upgrade the wheels at a later date. I may also add a suspension fork as well.
Thank you Lindsey Nguyen for the 60V battery bundle and a few bonus parts.
60 V 17.5 ah battery
750 Watts Bafang
7 Speeds 11-32
Other upgrades:, Seat, Seat post suspension, 53T crank and an upgraded throttle (no lights or power button)
Speed Test 60V 750Watts 35a Red Sondors
This weekend, I attempted 5 speed tests on a flat stretch of Lowry Blvd here in Denver. This is a straight shot flat road that if the flow of traffic is timed right, allows for a decent speed test. This is where I have tested all my Sondors from the original stock 350 with 8.8a battery to the dual 750 watts AWD bike and now the Red Sondors with Lindsey Nguyen's 60V drive train bundle.
I used Strava and the LCD to capture the ride statistics. The Strava results of the 5 speed tests are:
The highest LCD captured speed is 38.1 mph. I am not sure which is more accurate the LCD or the Strava's GPS results.
All these were with LCD C5 @10 and C14@3. These numbers were captured with full Throttle and pedaling at PAS5. With Throttle only, the bike reached 38mpg under these settings. Please keep in mind my red bike has 52T crank to go with 11-31 rear gears.
Under similar setting, my AWD dual 750Watts motor with dual 48V batteries has a top speed of 34 mph.
This bike has an amazing. Equally impressive are the interim speeds at the 5 PAS levels while on the highest LCD setting:
PAS1 19 mph
PAS2 24 mph
PAS3 29 mph
PAS4 34 mph
PAS5 38 mph, at this level I am seeing 1650 watts on the LCD.
Doing 31 mph is really easy with this set up. Keep in mind that This bike is set up with a 53T crank and 11-32 gears in the back.
I am officially calling this a 38mph test result even though I have seen 40+ mph performance. I will try again with a fully charged battery and on fresh legs. I am sure someone younger and lighter can easily exceed 40mph.
Overall I am very pleased with these numbers. Even under a tame LCD setting (c5@4 and C14@1) the bikes easily reaches 32 mph and I can pedal comfortably at 28 mph.
I will do a battery range test later. I anticipate 50 miles range on a more tame setting.
Thank you @Lindsey Nguyen for this amazing bundle. This is one fast bike.

Red Sondors 60V 750Watts project
Starting a new thread for the Sondors Red fat bike 60V 17.5ah battery, 35a controller, 750Watts motor, 7 speeds project.
Should I lace the motor to new rims? Should I use the stock rims? Should I consider a switch to 27.5 Plus rims? How about a suspension fork?
other upgrades for consideration, Brakes, Handlebar, Seat, Tires.
Wonder how fast or how far?
Stay tuned for more pictures and detailed progress reports. Appreciate your comments and input as this project gets underway.
