Aikema's impossible to deal with directly unless you're ordering large quantity and you can pay in Chinese currency to their "agricultural" bank. Over a year ago I tried to buy some replacement parts so I went to the NYC branch Bank of China in person and left with no reasonable secure way to...

Rockin' tip. If you have a moment could you share the measured highest/lowest voltage that model outputs adjusted maximum? Specs show 27-54VDC so if it reaches 54.6V it could be useful solution for 48V pack charging?

Li-ion/poly 13S (48V) fully charged = 54.6V Practically empty = about 40V

Happy for you Dan! Enjoy, the new'ish digs....

Safe travels road dog… Yeah, this stuff is reaching roughly 1lb per 100Wh and fairly well protected via BMS. Good times! But I would still treat ANY battery pack with care due a large amount of stored energy. Think about where you charge? Avoid messy, flammable areas as much as...

Other than storage don't mess with 80-90% SOC on any BMS equipped pack. Most BMS will never balance unless charged 100%. In practice, the main thing to avoid is sitting full SOC for more than couple days at time. If you know you won't use a pack for a few days or longer, merely charge to...

So it's ALL still Obama's fault? Precious, just absolutely precious, ROTFLMAO.... +1 eBike GWB...

Cellphones are more dangerous to the public than eBikes... de Blasio's a bum and tool for caving to the likes of Jessica Lappin and her cronies with their misplaced irrational vendetta against eBikes.

Balance only not for protection.

SLA capacity ratings when used for EV purposes should be divided in half. In other words, 40Ah labelled SLA capacity is only about 20Ah in the real world. That's why someone mentioned going to Lithium 20Ah and it would deliver the same range as the original 40Ah SLA.

Over 2k miles each on both a BBS02 and BBSHD and never greased anything. The 02 got a new controller after getting wet but that’s been the only work I’ve done to either system. I hear some freewheel noise in BBSHD when it releases but until it becomes nastier I’m not gonna bother opening it...

My shade tree trick to determine if an AC system is undercharged is blocking some air flow from a portion of the condenser coil. If the evaporator air goes colder while some of the “capacity” has been reduced then it can probably use a little more Freon. I learned this by accident on my home...

Some people use the USB programing cable for troubleshooting display/dashboards. It connects to the display plug and jumpers power ON pins without the risk of applying B+ to the comm wires.

No harm and if you want to prevent it from powering OFF disable the "auto-off" feature under display/dash settings.

I believe hub mounted battery pack is one of the dumbest things ever attempted for eBikes. Give 'em credit for trying but seriously, what a mess when something goes wrong.
