Re: Adaptto Mini-E/Max-E Owner's Thread

The first thing I noticed as I got this BMS is that it was balancing worse (maybe it pulls too little current to balance the higher cells) than my iCharger 1010B+ that balances up to 10S in a very accurate manner also if the cells are pretty old and degraded. It was with my older battery made with L...

Re: SURRON LB: RESEARCH & DEVELOPEMENT

It seems to me that given a volume is advantageous (greater Wh and greater V) use 18650 Samsung 30Q or Sony VTC6 instead of 21700 Samsung 40T

After market, why would surron make that kind of stuff =) With the help from Madin it looks like the next season for Light Bee will be very quiet! I will start offering these quite soon. Dont ask questions yet, full disclosure will be made once we fully test this kit out! So close now to finishing....

Re: E-S Stealth Electric Bike Owners

I ordered the black one I linked before on Aliexpress. I measured my present bar and it raise about 35mm so I will increase only 15mm with the 50mm riser bar but for €13,29 I can try it :wink: While In there I would change the left Handlebar grip that is pretty worn out but I don't find any 100mm ty...

Re: Adaptto Mini-E/Max-E Owner's Thread

You are having a strange behaviour with the firs cell always greater than the following 3.
I found out that using silicone wires on the 4S JST-XH connectors helps to relief the stress on the BMS.

Everyone has their own opinions based on their experiences, it's normal.

Subscribed!

Re: E-S Stealth Electric Bike Owners

I guess 380mm long is too much.
My battery is 370mm long and it's not very easy to fit, I need to insert the battery diagonally and upwards.

Re: E-S Stealth Electric Bike Owners

36cm ×15.5 ×11.5 is the size to fit in the bomber? Em3ev said they could fit 21 s 7p with BMS. 21S7P are 147 cells .... it seems a lot less than what we could fit there. I bet they use plastic spacers to hold the cells together. My 20S14P battery made with hot glued cells has the following measurem...

Re: Sur-Ron - New Mid drive Bike

I bet lvc on the cells are set to 3V and this will give us about 2.6Ah per cell. Thats 28.6Ah Usable. 57.6V*28.6=1647Wh and not some imaginary 2000Wh. So lets be real here. Add the bulky offroad motor tyres, belt and chain and you have a lot of drag compared to a hub motor. I will soon re-cell my p...

If you disconnect the main battery wires to the Max-E. Would the BMS still drain the battery?

You should always disconnect the BMS balance plugs before unplugging th...
