Re: SLA->Li upgrade options? Celllog 8S on SLA?

Thanks .. I did not realize that things like LV alarms/loggers have to be unplugged, e.g. when I part it at school. Os is that just because I may drain them so if I go for larger Ah could I just leave them in there. I gest that is One more reason to go BMS. Are the built in wires on the Lipo packs, ...

Re: SLA->Li upgrade options? Celllog 8S on SLA?

you meant that the LVC on the controller is 30V i assume. if you buy a lifepo4 battery then it will have a BMS with the LVC built into the BMS so your controller LVC is a no op. It is a "24V system". the 30V a possible max I read about somewhere when I was exploring using a 30V battery.. (cannot fi...

Re: SLA->Li upgrade options? Celllog 8S on SLA?

Thanks dogman.. Wow..i had no idea riding down to that level was so bad for it. Should I be plugging in at work (would be a real hassle but maybe doable if its needed as it gets cold). I figured I need a meter/alarm which is why I asked about the Cellog.. I know someday I'll have a Lithum pack.. so ...

Re: 18650 battery Kit development and discussion

Nice design, just they type of thing I'd want for an 18650 build. Understand that you can only make so many design. Not sure if it will matter.. but those of use stuck back at 24v.. would be interested in something 8s.. But here is my business arugment -- the others all variations seem to aimed at ...

SLA->Li upgrade options? Celllog 8S on SLA?

Background: I've been running my lashout (600w MAC +rear chain drive) on SLAs for a bit over two months. Two 12v12AH in series came with it; so I don't know their full history. I use it only uphill, my commute is +300ft and .8 to 1.5 miles depending on the route I take. A few days I run to the local...

Re: Newbie questions Lashout and BB-2590 (30v) Batteries

Well independent of the ability to use the batteries, I took the plunge and bought the lashout, I'm am e-biker Took it for a ride and had no problem getting to school, without getting my HR above 120. I pedaled at a good pace, but was able to maintain 15mph up the 8% and 10mph up the 10% grades.. Lo...

Re: Electrec battery/torque question

Realize this is an older thread but I'm curious if you ever ended up getting new gears to improve torque. I'm looking at a similar bike and have 8% and 10% grades on my way to work. If you did change which gears and how much did it cost?

Re: Newbie questions Lashout and BB-2590 (30v) Batteries

Thanks for the feedback.. Interesting I had not seen that thread. Good reading. @amberwolf I get the 28-29v for SLA, but the BB2950 can hit 33 which is my concern. No easy way to check the caps on an integrated controller and I don't really want to smoke it. Interesting to read your thread.. and the...

Newbie questions Lashout and BB-2590 (30v) Batteries

I'm a newbie on just getting into ebikes. I moved and my commute is now 1 to 2 miles (depending on path) but has some 8 and 10% grades, so while I can do it on a bike my heart is racing and I arrive at work sweating. I don't really want/need speed or really long range and want some exercise just not...
