Cells/cell groups can be recovered depending on the voltage reading, any cell/group voltage down to 2.5v should be recoverable. The means to recover individually depends if the user has the patience to do so, this can be discussed once the voltages are known.

I have various Lion & Lipo batteries/packs 3s, 7s, 10, & 13s which sometimes don't get used for months and they remain in good condition, the storage conditions and voltages are the important factor as is the checking the voltage of them every now and then.

Fully charging and leaving them in that state isn't down to how many years they last. Any effect is measured in total charge/discharge cycles and capacity retention over its usable life, it isn't as simple as some users assume it to be. That said a battery used regularly daily /weekly will be...

Tadpole trikes as these recumbent trikes are also known as use different leg muscles and can take some time to condition your legs to ride them, different muscles are used. In the past most user's convert or buy a readily converted model, a rear hub or a BBS type drive on the front boom...

As vfr and I have indicated access the BMS ribbon connector first and disconnect it ( the connector is white and will have 10 or 11 thin sense wires attached). When you have reached this stage we can guide you to take the necessary 10 cell group voltages via the ribbon/sense wire connector. For...

For 10 miles flat riding any decent ebike will do the job. For CS and warranty repairs the favoured forum sellers are most reliable Woosh, Wisper & Juicy also Decathlon appear to good as well.

Of which just looking at the options available none are suitable at all.

It depends on the controller system some use speed control while others use current control. Systems with speed control one will invariably not notice any difference in power as max current is supplied in any assist level, though max assist speed in each level will be different. Where as...

The TS BB is an integral part of the electronics fitted so it should be covered under warranty as is the drive whether mid or hub.

C1 try 06 & 07 setting as well as 05, the three values can give slightly different PAS feel. Also C14 2 is default, 01 is weak & 03 strong signal so worth a try. Other wise one could try a 8 or 10 pole disc's which will give a slightly slower pole count signal.

The battery receiver is wired to the controller so as vfr has mentioned short either the controller +/- contacts together or with the battery removed the receivers +/- contacts. A small spark as mentioned will occur but it will do no damage. IF YOU SHORT THE BATTERY ITSELF THEN IT WILL GO BANG...

One can if it is easy to do so open the battery and take 10 voltage readings via the BMS connector this will tell us if the battery is able to be recovered or whether it needs re-celling, replacing individual cells isn't really cost affective as any new cells will be working harder to carry the...

The controller is 48v marked for 48v nominal batteries so it should work for a 48v battery which when fully charged is 54.6v. Does the LCD have a voltage setting where 36v or 48v has to be selected ?

What I have and don't have is my business and not yours.

As Dave/vfr has said you have wired the batteries up wrong. They should be wired in series so 2 x 12v wired becomes 1 x 24v. The Blue line is the series connection where one battery + must connect to the other battery --. The other Black on battery #1 is the negative discharge and Red on...

A fine smear of Vaseline is all that is needed on metal. I use Vaseline on the metal work in my beehives to help protect the metal surfaces, I sterilise using Ethonic acid 80% to kill any viruses and spores present (sans bees)at the end of season (when cleaning ready for the new season in...

Sounds good, one needs to have faith. Though not sure she knows much about e bikes :rolleyes:.

My 961 has 9 assist modes.

I did think it through again and using the batteries as targets is much more fun.

One can also buy dongles for mid drive bikes or simply find hills to go down.
