Recently we received a lot inquiries about the replacement battery for Shengmilo MX03. Thank you for all your kind support! Some come with 2pin discharging port, and some with 6pin discharging port, both are available. The price for 25Ah is best ever due to the sufficient Samsung cells supply...

13S or 14S 30A BMS is max regular model BMS we can find to make it fit in the Dorado 21700 case, where there is only a very slim but long room for BMS. So 40A BMS might be possible with customized suppler slim long BMS, but customized BMS MOQ200pcs. In out solutions, usually BMS is sized at...

Thanks for your support! According to a lot real testing experience, the qualified standard capacity is set as mininum 95% of 25Ah, that is 23.75Ah. But the testing result will the influenced by many factors like the environment temperature, the discharging current, the testing machine deviation.

Agree, the 48V might be better for the bike with resticted controller. It is said that the NCM Moscow of Australia version has 15amp controller, while USA/Canada Version has 18amp controller. Even though both our 48V 25Ah and 52V 20Ah have a 30amp BMS, the controller will shut off earlier than...

"I modified the bracket to make it fit on the bike properly which took a bit of time. The battery just barely fits into the bike frame after relocating the mounting holes." Another 52V 25Ah Polly was installed as Rize RX Secondary Battery. Here are some pictures of the battery installed for...

It is okay if you can easy control to charge to 80%. This is a Dorado 25Ah capacity testing , 24.5Ah tested, battery voltage is about 43.9V/44V when battery discharging 80%, 19.6Ah, with 20% left. So you can set the controller cut off at about 44V. The BMS itself cut off voltage is 35.75...

For BMS with balance function, the balance voltage is usualy set as 3.8V, corresponding about 80% capacity. For the non-balance BMS, the BMS won't balance cells. Charging to 100% won't shorten the battery lifetime. The most important to care is : Don't overdischage the battery Don't store...

Yes, and no custom tax. It is DDP term (Delivery Duty Paid) . The shipping agent will ship the parcel to Canada and pay for the tax, with UPS delivery to door.

The BMS we choose is Super Power brand non-smart 13S 30Amp, no balance function. The Samsung cells voltage consistency is very good, so the balance function is not necessary. All our ebike batteries use the Super Power BMS, basically no defective products.

Thank you for your trust! @PCeBiker

Agree, I think 52km with 2bars left, that is not bad. The battery cutoff voltage is about 39V. Also the discharging capacity is a bit less in low temperature riding. In our mass production capacity testing, the 25Ah tested capacity under 10A discharging, is about 24.5Ah in Summer, and only...
