No. The poxy thing's still blocking up my wood workshop, which I can hardly get into because of stuff like that. The battery is outside in case it "does something". The cells in it aren't 18650s, they're flat (well, supposedly flat) things "in bags". |
My original lead acids were 12kgs, the lithium replacement was 7kgs, with the same capacity, but at 48V. I wouldn't choose the lead acid route
Ok, if Easy-X is correct you already have lion batteries... we have questions, which'll save loads of posts.
1. What make of tricycle.
2. Factory fitted electrics or retro/DIY.
3. Power of the motor.
4. Part Number of existing 'bags', and confirm quantity.
5. Declared voltage & mAh output, (the Chinese seem to be in a badge engineering war with fictitious capacities).
6. Photos would really help.

OK, sorry for the delay, I've just found the battery. My info inline. GettinBetter wrote: | Ok, if Easy-X is correct you already have lion batteries... we have questions, which'll save loads of posts.
1. What make of tricycle.
It's a Batribike Trike 20 with a horizontal battery box under the rear basket.
2. Factory fitted electrics or retro/DIY.
I think that the battery is the original one.
3. Power of the motor.
Motor: 250W front hub brushless
4. Part Number of existing 'bags', and confirm quantity.
As attached photo, I hope.
5. Declared voltage & mAh output, (the Chinese seem to be in a badge engineering war with fictitious capacities).
Hm, tricky. Battery Power: 36v 10Ah (from: https://www.e-bikesdirect.co.uk/brands/batribike/batribike-trike-20-electric-trike)
6. Photos would really help.
Attached.

There's a sales video here: https://www.youtube.com/watch?v=Vt7z0udPT_4
It's one of these tilting things that is safer when cornering than a rigid, although it feels very dodgy until you know what to expect. It belonged to an elderly relative who won't be using it any more, and it's been bunging up my wood shop for too long.
Can't quite make out the first couple of characters of that battery part number (looks like JD7065120PP ?)
I *think* it's that.
Ok, So 20 packs at 3.2V = 64 V
So they must be 10 in series and 2 in parallel, giving 32V.
Fully charged they would actually be around 3.4/3.5 maybe higher and hence closer to the 36V expected.
Until it's tested you can only assume the control system, and the BMS is working fine, same goes for the charger.
Have you ever used the bike/had it running? That would clear some of those issues up.
I have been on it, about 3 1/2 years ago, and it would do about a mile before phutting out, I assume with flat batteries.
If it's just batteries then replacing like for like (if still obtainable) is the easiest option.
I'd search for same:
1. Voltage.
2. Capacity (or better, but remembering anything that sounds too good to be true... ).
3. Discharge rate (Very important).
4. Charge Rate (Very important).
5. Dimensions (if you want to use the same case).
Searching will at least give you some idea of the costs involved. |
I will have a look. It seems that since I last looked, a couple of years ago, the price has risen. |

This looked interesting...
https://www.youtube.com/watch?v=aNksyf2VqKo
Might also be worth sending a generic email to a couple of Batribike dealers to see if they can supply a new one, you never know... might be reasonable, compared to all the faffing to replace the cells.
Just a thought...
Also this company seems to be highly recommended.. so no harm in asking..https://ebikebatteries.co.uk/contacts/ |

It's possible I can get a replacement. However, there are a couple of options.
1) Buy another complete battery pack & charger, e.g. Samsung one here: https://www.aliexpress.com/item/4000290976528.html?spm=a2g0o.productlist.0.0.664b1992i1hc9y&algo_pvid=3c98252a-8ab7-48f5-b070-546e0922830a&algo_expid=3c98252a-8ab7-48f5-b070-546e0922830a-2&btsid=0b0a0ac215831923706583507eff89&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ and stick it in the existing casing, easy to do, IF it's likely tpo work...
2) Re-cell, see if the charger works, PITA, no guarantee other components OK.
3) Replace the battery with 3 x lead acid e.g. 12V 15Ah = (£90-ish, trihe so pooh to weight).
4) A Batribike battery (unsure if available for "old" models) is nearly £400.
Sort of tempted by (1), but I freely admit I have not the faintest idea whatI'm firing at, or whether that would work. It looks as though it might. What do you think, please? |

Just a thought, but I still have the three 12V lead acid batteries I took out of my bike, I don't know how far away you are but you're welcome to try them to see if you bike runs ok? Hell you can even have them if you want?
They where only a year old when I acquired the bike from my brother, he was a bit miffed when I told him I'd lobbed his trusty batteries, but hey I bought it, so can do what I like.... that was a year ago I keep them charged.
On the other hand, this is no quick fix, if you want to do it properly, there are countless options available, and after days even weeks of surfing the net you'll settle on something you can live with. Also there's a ton of research if you're new to electronics. Getting familiar with the subject takes time.
I had a look for that part number, and didn't find anything. Maybe there's a cross referencing/equivalent list, out there somewhere, that'll be the next step? |
