I managed to fix the inverter with fuses. Seems I had reversed connected the wires. I also purchased a 25w 30 ohm resistor to charge the capacitors. Even with the resistor there was still a little bit of sparks, but nevertheless I was able to connect the battery to the inverter. Connected a 61w...

The inverter is a 2000w pure sinwave inverter. No clue about its quality (their 24v inverted combined have 106 votes for 3.9 rating average). From amazon: https://www.amazon.ca/gp/product/B074C8Z1M3/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 The Chinese cells definitely might have been the...

Background: I don’t know much about electricity. I have a 14s5p battery that Id connect to my inverter (rated to handle 40-60w DC). The few times ive used the inverted it has never been an issue (always keeping battery under 58v). My battery would connect using Anderson connectors, id turn on...

Is low current an issue when charging these packs? Even if you keep voltage steady, wont a very slow amperage degrade the battery and/or components if it needs to be ran + 7 days for a charge (which during that time the amperage would probably be 0.5c to 0.1c then divide by 5 since its a 5p...

Yea this is the only other thing written on the battery. I did send the seller of these cells on alibaba a message asking if they still sell them.

Wow, thanks, don't know how you found that. That matches my charger (I had assumed they just threw me a random cheap charger.) Short history of my battery: My e-bike would die within a few minutes, so I sent in the battery for repairs (it was under warranty). I got it back, worked fine for...

Bump? Anyone got any idea where to even start looking? I figure worse case scenario I can sort of try to 'rebuild' the battery with only 12 of these in series.... Tho that would mean id need a need BMS and my current charger wouldn't work.

Measurements of the single cell: 5.5", 2.5", and 5/8" For the third time my battery from my ebike has failed me. This time I am out of warranty so I took the battery apart and saw it was 13 unknown Chinese 'cells' in series. All of them showed 4.1v, expect for one showing ~0.4v which seems...

Thanks, its a good sign, we will see if I get the same luck. I placed my order about a week ago. Not shipped yet tho, it was delayed when they saw I had no charger as part of my order (ordered the satiator from ebikes as the price is about the same + 0 chance of duties issues from a canadian...

Yea definitely interested to know once it comes in. And even how long it took from time of order to delivery.

As the title says, any Canadians order from em3ev? From my understanding batteries are category 4... So this would mean you pay 8% duties plus the GST/HST? So someone from Ontario pays 13+8 = 21% higher then listed price, or am I missing something?

Here is picture of bike and the battery with the back cover open.

Thanks for the reply. Think my latest plan is to get the 52v pack with the Satiator. Will probably setup my main profile to charge to 3.8v*14s=53.2v while also having a 3.9 and 4.0 profile for 54.6v and 56v for a few rare longer trips per year. In theory that should give me lots of power and put...

I have have 500 watt motor (says Shengyi hybrid on it) and some unknown controller. My current pack is dead after storage in the winter (was a 'free' rebuild, I opened it and it looks like they threw in 7 of some sort of polymer batteries). Want to buy a new battery, thinking of a 13S5P Samsung...

My current battery has been in the 'shop' for about 4 months in Toronto (they put in fake Chinese cells and they failed quickly). Not sure when I am getting it back and I am thinking of buying a spare/backup battery. Current bike uses Anderson connectors. I am thinking of maybe buying this...
