upgraded BBHD controler - Thanks Luna Cycle !

[brothergc]

A while back ago I attempted to program My Bafang BBSD with my Luna program box . Noticed that when I tried to change the amp setting from 25 amps to 30 , it refused . So I took a chance and bought a new controller from Luna Cycle . That did it ! came preprogrammed set to 30 Amps . I have not had a chance to try it out yet . Weather here is below freezing !
Wanted to thank Luna Cycle !
I will update the thread once I get a chance to try it out , but so far so good.
Replacing it was not too bad , except for one small connector that was covered in silicone I had to pick away at
here is the vid I used https://www.youtube.com/watch?v=rgFQK-ID8AM
here is the controller

Again Hats off to Luna cycle !

Finally got around to testing the new controller . Noticed a definite upgrade . A Lot more torque and smoother throttle response for My half twist throttle .
The PAS seems well balanced , no need to reprogram .
I have yet to test a long trip , but plan to on my vacation time coming up soon .
One a separate note considering a battery upgrade . How good are these Electrify Bike CO batteries ?

Hoping these are top shelf feedback is appreciated ! :)

I think they're good and stout batteries (I have the 21ah (18650) and 25ah (21700)), and have the latest, strongest tray available. They are UN 38.3 certified (but not U.L.)

These batteries are very heavy, so I would anchor the tray down using at least three, but preferably all four mounting holes.

The shipping originated from Utah and was relatively quick, but via ground.

Thank You for the reply... Seeing that You have experience with both batteries could I get Your feed back on both the 21ah and the 25 ah , like weight and range between the 2 . Do you think that the larger one is worth the extra cost ?
Thanks in advance . :)

I use these bigger batteries mostly for grocery errand runs, getting the perishables home fast.

I curse the weight when carrying the bike up the stairs, once back home.

We almost always want more range and/or speed - as long as the added weight penalty can be tolerated. We usually can't recharge once riding, and conditions can change, such as headwinds, route issues, etc.

As far as cost, I reduce expenses elsewhere and splurge on this hobby.

I was hoping for a more comparative details between the 2 batteries seeing you have both of them . , I am debating if I wanted to go with the 20 amp hr or the 25amp hr . Weight differences and battery life as well as sizes .

Please keep in mind that my 21Ah battery is the slightly older, 18650 cell model - not the current 20Ah 21700 cell model. It may be possible to fit the 20Ah 21700 cell arrangment into the next size down case.

So, in my situation, the 25Ah battery is 0.5 inches taller and 2.1lbs heavier than the 21Ah, and the 25Ah battery has a 50amp BMS versus 40amp for the 21Ah battery. The 10 amp BMS difference wouldn't likely matter with your current motor configuration.

I don't have enough seat-of-the-pants time (nor like, repeated ride conditions) to estimate a percentage value more range between the two.

5 amp hours could be another 10 miles ish of range so going from 40 to 50 ish, as they say your mileage may vary. Is that all in one go? Or is it a situation like you are riding to work and can't charge there? For many of us 40 miles is a long time to sit on a bike and we kinda coined the term ass hours which becomes your new range limit. But like NCM points out there are situations where you may want or need to get somewhere faster or with little or no pedaling for one reason or another which takes more power. Say you planned a 40 mile ride with your 20ah pack and that is moderate speeds and some pedaling. You suddenly need to go faster or hit a killer head wind you may run out of range but that extra 5 ah could be the reserve you need. If you can afford the space, weight, and cost I too would say go bigger. Like was said above, the only people say their pack is too big is those that have to pick it up and carry it very often.

thanks for the input. Seeing that the 25ah battery is $100 more I am thinking that a few extra amp hs are just not worth it .
