The battery may give off fumes if it becomes damaged or is used incorrectly. Ensure the area is well ventilated and seek medical attention should you experience any adverse effects. The fumes may irritate the respiratory system. We used to have the smaller Hailong-01 enclosure in 36V 16.5Ah (10s 5p) layouts suitable for 20-25A current setups, and the larger Hailong-03 enclosure in a 52V 16.5Ah (14s 5p) size for higher current and capacity, but we have nowswitched to only Reention Poly-DP casings for a standardized cradle, stronger casing, and more reliable connectors. For extra large capacity (>1 KWhr), we have the Reention DP-9C casings in 36V 26.5Ah and 52V 20Ah formats.We also have downtube enclosures for the larger 21700 cell format and have these available in 36V 14.5Ah, 36V 19.5Ah, 52V 14.5Ahand 72V 9.5Ah options with Panasonics NCR21700Acells (same as used on Telsa 3), and also in a 72V 7.5Ah format using the very high power capable Samsung 40T cells.

Easy to Fit, Attaches to standard water bottle cage, also comes with bullet connector plus XT60 connector Ambient temperature will affect the discharge capacity, if the ambient temperature is beyond the standard environment (25±5 ℃ ), the discharge capacity will drop! Of course, if you go really fast or are pulling an extra load, then this mileage will be worse, like 12-15 wh/km. On the other hand, if you use the motor more sparingly, then you can easily stretch it down to 6-8 wh/km. The table below summarizes the expected range for these different example batteries under light, average, and heavy usage paradigms: https://myelectricbikemotor com/electric-scooter-moped-bike-850w-48v-brushless-motor-lifep04li-ion-20ah-battery/

The tabs on the base of the case and the slider (these hold the battery to the slider) are very thin on the Hailong case (~2.7mm) and poorly supported/designed. Also, due to the Short length of the slider (due to the controller), there are only 6 tabs. Do not place the battery near flammable materials. Ensure the battery is completely dry and placed on a fireproof surface before charging. There is a risk of fire due to the heat generated during charging. Cleaning ---- Cleaning with a direct water jet is impermissible, in particular to protect the electronic components. Before cleaning the eBike, remove the battery. Occasionally clean and lightly grease the connection port.

On the Bikonit HD750 I can hit a max speed of 32mph (peddling) on flat land and get a range of 51 miles in PAS 5 and 78 in PAS 3 on the dual 15ah batteries https://myelectricbikemotor com/new-2021-crx-dirt-bike-36v-500w-kids-electric-dirt-bike-motor-bike-motocross-2/ I subsequently replaced the 15amp BPM with a 30amp BPM that prevented this issue from occurring, as the OEM batteries from Cyrusher come with a 30amp BMS. However even doing so I never got more than 20 miles out of a rated “30ah” Hailong bought on Alibaba regardless of the PAS settings but the 17ah from Cyrusher gets 48 miles using the same PAS settings and all things being equal (i.e. same path to work, same stop and go, same speed, same PAS, etc.) The Shark style case is a popular choice, due to it’s small size, for it’s relatively high capacity. It’s long, but sleek profile, means it can fit into most frames and it looks pretty good. However, it was not all good. The Hailong case that was used for most of the Shark batteries that are in circulation, suffered from several issues. The issues on the Hailong case included:When the battery is not in use, keep it away from paper clips, coins, keys, nails, screws or other small metal objects that could make a connection from one terminal to another. A short circuit between the battery terminals may cause burns or a fire. Short circuit damage which occurs in this instance voids any and all warranty claims against TrikExplor.

DMEGC do seem to have a pretty big, swanky factory, they claim making 80,000 x 18650 cells a day (among many other cell types). If Fiido alone are selling (a claimed) 400,000 e-bikes a year, taking typically 40 cells per bike, that's 16 million cells a year - which is 2/3 of DMEGC's stated lithium cell capacity. That may be why other makers don't get much of a look-in and why people like Mooch haven't come across them? I work for an Electric car manufacturer, and have access to some testing equipment and a lot of smart people that know about how all of this works, I have done some real world research as to fine tune my e-bikes for the best range and speed I can get. The all new Big whale down tube battery is perfect for Bafang BBS02 , BBSHD, Pedalease 1500W Fat bike kit and many more . Do not open the battery. There is a risk of shortcircuiting. Opening the battery voids any and all warranty claims.Mounting base ---- The Hailong I-2 mounting base with space for a 9G 11-22A 500-1000W built-in controller. The output connectors could be waterproof or non-waterproof. The conversion kit is the best quality and relative low weight, the motor is sleek making it easy to pedal even without power The conversion kit is capable of accelerating to the off road speed of 40 mph and by selecting different modes you can ride to reduced limit of 15mph . Hailong battery case has the following models: Hailong I, Hailong I-2, Hailong 2, Hailong plus, Hailong Pro, Hailong G56, Hailong G70 and Hailong G80. All these models with similar design, but different sizes for installing different number of battery cells - 18650 and 21700. Currently only the Hailong G80 available for 21700 cells - maximum 52pcs for 10S5P or 13S4P.

I subsequently replaced the 15amp BPM with a 30amp BPM that prevented this issue from occurring, as the OEM batteries from Cyrusher come with a 30amp BMS. However even doing so I never got more than 20 miles out of a rated “20ah” Hailong That i bought on Alibaba regardless of the PAS settings but the 17ah from Cyrusher gets 48 miles using the same PAS settings and all things being equal (i.e. same path to work, same stop and go, same speed, same PAS, etc.) Our Jumbo Shark comes with a high current charge plug, rated for around 8A. Our 2-wire type BMS means you can actually safely charge through the discharge leads as well. KD21C LCD can provide a lot of functions to fit the users’ need. The indicating contents are as following.hopefully this info is helpful to someone. I was bored this morning, so y’all get to read my long winded post.
