I have the malectrics for some years now and it just works for me. I also loan it to people, never had any complains (other than human error, like using a low amperage Lipo pack). Battery recommendations are in the FAQ on its website. However I would -maybe- go for the kweld today. Years ago...

Calculated at 1kWh the LiIon will cost you 224$ while the Lifepo4 costs 278$. Thats the 50 bucks holding you back? I'd say if you are familiar with the chemistry etc... But ok. The 48v 20Ah LiIon has the energy of like 80-100 18650. 215$ is imho cheap for this amount of Wh assembled as a pack...

Right before soldering this "100A" BMS on a new 3S-Pack I figured the placement of this resistors are slightly off. Before I try to move them (and/or destroy it by doing so :)), does anybody know if this is a problem at all? I looked at another BMS of this type (4S tho) where the placement is...

I stopped using BMSssses on my bike batteries (have 3 now, ~750Wh, ~300Wh and one with ~120Wh) because on the biggest pack the (el cheapo) BMS failed once. Glad the pack survived. So I will not fool around too much about circuits to monitor and shut off this and that. Think I'll just go the...

Hi, I am aware of 3.6v <> 4.2v. This is not the topic here. My 14s-charger died (58.8v) and I need replacement. To prolong the batteries life (by, well, just a bit) I though about this 16s LFP-charger -> https://de.aliexpress.com/item/1005003682689596.html My question: are cc/cv charging...

Hi, I am rebuilding a Pack for a friends Mower right now. The owner got two original 30S1P (nominal 120v) batteries for it (but the mower just takes one at a time), both packs died just after a couple times of using them (no wonder with Samsung 29E cells (10A)... and its a huge Mower lol). I...
