Battery AW17670 protected or Sanyo 16650 unprotected?

[AceAngel]

I will be receiving my Ti B 532nm soon, as I'd expecting the DHL Express courier to be in these few days.

The unit will be here without any battery.

I'm planning to purchase either AW 17670 protected or Sanyo 16650 unprotected. I had heard that those Sanyo batches was actually some old stocks, is it true?

Does anyone here experienced with both batteries before?

Thanks in advance :thanks:

For lasers, for the most part, IMO you should use unprotected batteries.

You just need to be monitor how long you have the laser on, make sure you don't kill the battery discharging it to below 3.0v.

AW and Sanyo batteries are considered good brand. You can't really go bad with either of them.

Depending on the current draw, the protection circuit could make the AW unusable. Also the protected AW will be a lot larger vs the unprotected sanyo.

Thanks, great info.

What about, if putting in 2x 16340 instead? Will it be ok?

You should be able to find a Sanyo 17670 cell.

Either cell will work fine.

I have slightly enlarged some 17670 hosts, to take a #18650 cell.

That also provides a more powerful solution.

Wow....that was hard to find even with the help of Google.
All these 17670 or 16650 were mostly supplied by Chinese companies. Most of them had stop taking in orders due to Cheese New Year preparation and shall commence business again on late February 20~25th.

I'd recommend boring the host for 18650 if possible. Otherwise, go with Aw protected or, if you are good at measuring your cells regularly and understand the hazards of Li-Ion and how to diagnose/defuse dangerous malfunctions, go with the unprotected 16650.

Generally speaking, protected batteries are the way to go for most laser users. If the protection circuit trips, chances are you have a short somewhere in your laser. AW states that the protected AW17670 trips at around 5A draw.

Boring out the TiB would be kind of tough... I've head titanium is a major pain to work with.

The reason I'm recommending the unprotected Sanyo is based on my experiences with the older model TiB lasers.

For the older, a protected AW 14500 fit fine. Unfortunately the protected batteries from other suppliers (Keeppower Orbronic) do not.

I had asked the shop dealer, he was very helpful and he told me this:

Currently 16650 was in low demand and do not expect much from its performance. If you really wants a good one, you should check Japan eBay. On the other hand, he adviced me to use the protected one for safety. Unprotected is AW 17650 while protected one is AW 17670, 2mm length difference.

AW 17670 protected cell fits into Ti B perfectly. Everything runs smooth and start lasing like Dennis the Menace. :lasergun:
