416 OFPPK 18650 solderless solution

Good news... Remember the 416 OFPPK (solderless solution) I released a few months back. I decided to open up the design file at a small cost. Those who have access to CNC & laser machine or machine shop locally can benefit from this release. You can fabricate as many pack as you like without incur ...

Re: connections without DIY welding / soldering

Thanks, this is during the pilot run stages, will be better once the quantity goes up. Do check out the latest update on the 416 OFPPK fb group. This looks promising, but IMO overly expensive cost per cell. https://danlimblog.blogspot.com/2018/10/p1-416-open-frame-power-pack-kit-its.html?zx=90926629...

Re: What battery to choose after your last one burned your house.

Consider using LTO Battery LTO66160, is one of the safest battery in used.
It has high discharge rate and capacity. Its being used by lots of Electric buses..
Thou is more expensive, the safety wise is more than the cost itself.

Re: First battery build

When building bigger pack... many consideration is needed, not just adding battery. There's three most important areas that need to be applied. Safety, Environment protection and Ventilation.

Re: PARALLEL THEN SERIES VS SERIES THEN PARALLEL BATTERY

Option 1 & 2 is the same... both will give you 3S2P. In general, add battery in series will give you more voltage, adding battery in parallel will give you capacity. This is what most of the battery pack are made off.. Unless you're going for very big battery pack that need to spit the battery separ...

Re: First battery build

Nice try.. Quite similar as my newly develop 416 Open Frame Power Pack kit. http://bit.ly/416OFPPK Soldering is fine if is for small area. When you have large area, the consistency will be affected. Another disadvantage of soldering is it fixed. Cannot change. Of course, the benefit is you have a la...

What are the dimensions of the frame fully loaded with 14s cells? I need 3 1/2" x 3 1/2"
The arrangement is 4x16... overall is about 400 x 94mm. This may not fit to your ebike.

Re: 416 Open Frame Power Pack kit

Yes.. this is cater more towards powerwall or external power pack. For ebike, unless it is a common model, the shape is the same. There's too many variation in size or shape.. is hard to justify which one to go. If space is not a issue, this maybe able to reconfigure to your need.
