Andy to over volt means using a battery of higher voltage then your 36v so convention says 48v is better, it will give 33% more speed and torque over the 36v set up. A 30amp controller is too much for a 36V system and not necessary on a 48v system unless you have the very best cells inside the...

The only 2900mah cell from Samsung is the poor/mediocre 29E, the 2900 PF is a far superior battery for amp draw and is a proper 10a cell though in reality it appears that 2700mah is more like it's true capacity. Still a very good cell for he price.

Battery cycle life can probably be halved when using a dongle as the speed has to come from somewhere even if fooling the speedo, it doesn't appear out of thin air.

How varying were the mosfet results ? Generally all between 9 - 10 ohm reading indicates all should be well, if one is diversely worse then the other two then needs replacing. Throttles can cause issues from moisture ingress. Juddering is often a phase fault usually wrong wire sequence which...

At a guess 15.6ah suggests they may be Samsung 26F 60cells (10s 6p configuration) most likely they will struggle when drawing high amps on hills or in a higher assist level (3 or more), so you may experience cut outs as the cells struggle to deliver the power asked and voltage will sag collapse...

You won't be disappointed.

Use this web address link https://ebikebatteries.co.uk/contacts/ Jimmy has three legit tech companies we know of that operate from the same North London modern premises, each in a slightly different tech sector though all are interlinked/crossover with each other. If you phone him make sure you...

If you want to keep a TS system instead of modifying to a cadence type system then or about $158 inc p&p you can get a new TS bottom bracket kit with TS controller and lcd3 etc,etc from BMS battery for hub motors. Replace the crappy Suntour stuff with more user friendly pretty reliable Kunteng...

Jimmy arranges pick up and delivery of your battery, speak to him let him know which generation of Bosch battery you have and he will upgrade it with better cells and more wh for about half the price of a new battery. He will most likely tell which cell though don't worry as he only uses to top...

Torque should be greater as by sounds of it you are upgrading to higher spec controller, the torque will be mostly the same whether 250 or 500w. Though I doubt your 36v battery will be grateful for having to supply 30a discharge If asked to, you don't say what the battery or cell product is used...

Don't try it with any voltage in the system as you could short the controller if v+ is always live. Simply cutting through in one fair feel swoop would most likely lead to a short and controller damage if v+ is constant when power is applied. When cutting any wiring each wire should be cut...

:cool: 60a continuous bms (180a over current) on it's way , < £16 :D.

Jimmy say no more.

Give a liberal slop of grease or a good cup full. Graphite grease should be ok.

For about $158 inc p&p you can get a new TS bottom bracket kit with ts controller and lcd3 etc,etc from BMS battery for hub motors. Replace the crappy Suntour stuff with pretty reliable Kunteng KT software.

Quite a bit of rust in there B2, moisture/water as some stage has found it's way in. Noticeably there is a lack of grease, the hub will run a lot quieter and smoother if the planet gears and outer gear ring is well coated. On the lhs side you may have to undo a retaining/bearing nut for the...

If you have deeper pockets Sony/Murata vtc6a are very good cells. 30Q or Hg2 otherwise. PF is a lower capacity cell but holds on to power well. GA is 10a and good for it.

Dongling the bike will make the battery work harder then it was designed for so it's life will suffer. The faster speed will demand more power from the battery.

My old Oxydrive kit had 26F as 10s5p config, they were ok for about 20 months then lost some capacity which means range was some what reduced by some 30%. Usage was mainly pas2 or 3 so no real big amps drawn, I bit the bullet and de constructed the pack to make some 6p 15.6ah 3s booster packs...
